A Comparative Study of the Chemical Composition and Skincare Activities of Red and Yellow Ginseng Berries

Abstract

This study was conducted to investigate the differences in chemical composition between red (RGBs) and yellow ginseng berries (YGBs) and their whitening and anti-aging skincare effects. The differences in the chemical composition between RGB and YGB were analyzed by ultra-high-performance liquid chromatography tandem quadrupole electrostatic field orbit trap mass spectrometry (UHPLC-Q-Exactive-MS/MS) combined with multivariate statistics. An aging model was established using UVB radiation induction, and the whitening and anti-aging effects of the two ginseng berries were verified in vitro and in vivo using cell biology (HaCaT and B16-F10 cells) and zebrafish model organisms. A total of 31 differential compounds, including saponins, flavonoids, phenolic acids, and other chemical constituents, were identified between the two groups. Superoxide dismutase (SOD) activity was more significantly increased (p < 0.05) and malondialdehyde (MDA) content was more significantly decreased (p < 0.01) in RGB more than YGB induced by UVB ultraviolet radiation. In terms of whitening effects, YGB was more effective in inhibiting the melanin content of B16-F10 cells (p < 0.01). The results of zebrafish experiments were consistent with those of in vitro experiments and cell biology experiments. The DCFH fluorescence staining results revealed that both ginseng berries were able to significantly reduce the level of reactive oxygen species (ROS) in zebrafish (p < 0.01). Comparison of chemical composition and skin care activities based on RGB and YGB can provide a theoretical basis for the deep development and utilization of ginseng berry resources.

1. Introduction

Panax ginseng C. A. Mey., one of the traditional Chinese herbs, has a variety of pharmacological actions and therapeutic effects [1]. Ginseng contains saponins, polysaccharides and active peptides, which have a variety of active effects including antioxidant, anti-aging and whitening [2,3]. The aboveground parts of ginseng include roots, stems, leaves, flowers and berries. Ginseng berry is the main production area in Jilin Province, China, and its production is abundant, which can reach more than 800 tons per year. Modern pharmacology has shown that ginseng berries can improve cognitive function, memory, hypoglycemia, anti-inflammatory, and many other pharmacological activities [4,5,6,7,8,9]. In recent years, a variety of chemical components have been isolated from ginseng berries, including ginsenosides, polysaccharides, amino acids, and inorganic elements [6,10]. The relevant literature suggests that ginseng-berry-mediated metal nanoparticles can be utilized as novel cosmetic materials for skin care [11]. Heat-treated ginseng berries were able to enhance the conversion of rare ginsenosides Rk1, Rg5, and Rg3 and inhibit melanogenesis by inducing autophagy [12]. The (+)-syringaresino in ginseng berries accelerates cell proliferation and has the potential to promote skin healing [9]. Therefore, ginseng berries have the potential to be developed as a cosmetic ingredient.

The combination of aging and UVB radiation aggravates cell metabolism, which in turn produces melanin deposits [13,14]. The pursuit of natural cosmetic ingredients has become mainstream in today’s society. Natural berries and seeds are rich in flavonoids, vitamins, carotenoids, anthocyanins, and many other antioxidants [15]. Red goji berries and black goji berries (Lycium fruits) contain high levels of polyphenols with strong antioxidant properties [16]. It has the effect of relieving oxidative stress, anti-radiation, and anti-aging [17]. The colors of mature ginseng berries are classified as red, yellow, pink, orange, etc. YGB is a new ginseng variety endemic to Jilin Province, China, and is a pure recessive mutant of the traditionally cultivated RGB [10]. Currently, there are few basic studies on the efficacy components of the germplasm resources of the new YGB cultivar. The differences in chemical composition and related activities of ginseng fruits of different colors are inconclusive.

Ultra-high performance liquid chromatography tandem quadrupole electrostatic field orbit trap mass spectrometry (UHPLC-Q-Exactive-MS) coupled with multivariate statistical analysis has been widely used in the field of pharmaceuticals and food development with a high resolution, sensitivity, rapidity, and throughput [18]. In this paper, we intend to analyze the differences in the chemical composition of two ginseng berry colors and initially elaborate the differences in anti-aging and skin-whitening activities of different berry colors to provide a scientific basis for the development and utilization of ginseng berry resources.

2. Results

2.1. Differential Compound Analysis of Ginseng Red and Yellow Berries by UHPLC-Q-Exactive-MS

As shown in Figure 1A,B, the total ion chromatogram(TIC) of the ginseng berry sample was well separated and had a high response value in the negative ion mode. The RGB and YGB have different contents and types of chemical components. The multivariate statistical analysis revealed that the PCA showed that the total variance explained of the samples was 81.6%, indicating that the model was stable. The analysis of OPLS-DA results showed that the total-variance-explained rate of the samples was 81.2%, which indicated that the reliability of the model was good and the samples could be clearly distinguished between the two groups. The OPLS-DA was further tested using a permutation test. The number of randomized tests was set to 200, and the results showed that the intercepts of R² and Q² with the Y-axis were 0.473 and −0.257, respectively, indicating that the model had good predictive ability. As shown in Figure 1F, the metabolites with significant differences (VIP > 1) were screened using S-plot diagrams. This indicated that the model was well separated and stable, and that the two fruit-colored ginseng berries had large differences in their chemical compositions. The results of cluster analysis showed that YGB and RGB could be clearly classified into 2 groups. As shown in Figure 1G, the high expression zone of differential compounds in YGB totaled 28 chemical components, mainly ginsenosides and phenolic acids. Based on the importance values of the projected variables (VIP) in the OPLS-DA model, combined with the t-test and the multiplicity of differences (FC), the differential compounds in the two berry colors were screened (VIP > 1, p < 0.05, FC > 2). Based on the m/z values of the single isotope peaks of the differential compounds, the ion fragmentation and retention time were imported into HMDB and PubChem databases for matching, and a total of 31 differential compounds were identified, as shown in

. Based on the obvious hybridization between RGB and YGB germplasm resources, there are differences in the content and nature of their chemical components, and their pharmacological activities have significant differences.

2.2. Determination of Antioxidant Capacity of Red and Yellow Ginseng Berry

For calculating the FRAP reduction ability, the following regression equation was used: Y = 3.762 x + 0.1627 (r = 0.9994). The antioxidant capacity of the samples was assayed using Fe²⁺ to generate a blue–violet complex with TPTZ under acidic conditions. As shown in Figure 2A–D, ginseng berries were found to have greater free-radical-scavenging ability with increasing drug concentration, as measured by a total of four antioxidant indicators DPPH/ABTS/OH/FRAP. The IC₅₀ is commonly used to evaluate the antioxidant activity, and the smaller the IC₅₀ value, the stronger its antioxidant property [19]. Both RGB and YGB possessed strong antioxidant activity, and the antioxidant capacity of RGB was found to be slightly stronger than that of YGB by IC₅₀.

2.3. Comparative Quantification of Chemical Composition of Ginseng Berry

For calculating the total flavonoids content, the following regression equation was used: Y = 7.12x+ 0.0500 (r = 0.9999). The Y-value is the absorbance value of SGW, while the X-value is calculated using the same formula used to obtain the total flavonoids content.

For calculating the total saponins content, the following regression equation was used: Y = 11.23x+ 0.0247 (r = 0.9998). The Y-value gives the absorbance value of SGW, and the X-value is calculated using the same formula used to obtain the total saponins content.

For calculating the total polysaccharide content, the following regression equation was used: Y = 1.6769x+ 0.1166 (r = 0.9999). The absorbance values were substituted into the standard curve as Y-values, and the X-values were calculated to obtain the total polysaccharide content.

For calculating the total polysaccharide content, the following regression equation was used: Y = 0.028x+ 0.1677 (r = 0.9997). The absorbance values were substituted into the standard curve as Y-values, and the X-values were calculated to obtain the total polyphenols content.

As shown in Figure 2E–G, the ginseng berry constituents were found to be significantly different by a total of four content determinations of total flavonoids/total saponins/total polysaccharides/total polyphenols. As shown in

Table 2. Determination of antioxidant capacity and content of red and yellow berries

		RGB	YGB
Antioxidant capacity (IC50)	DPPH	0.576 ± 1.052	0.657 ± 0.263
	ABTS	1.044 ± 0.548	1.050 ± 0.846
	OH	0.023 ± 1.320	0.049 ± 0.985
	FRAP	1.481 ± 0.895	1.646 ± 1.223
Ingredient content (%)	Total flavonoids	3.772 ± 0.078	1.879 ± 0.050
	Total saponins	17.199 ± 0.901	26.921 ± 1.352
	Total polysaccharide	22.675 ± 0.632	19.021 ± 2.044
	Total polyphenols	1.925 ± 0.079	0.999 ± 0.044

, total ginsenosides of YGB ginseng were found to be higher than RGB by chemical quantification, which is consistent with previous results. The statistical results of non-targeted metabolomics in Table 1 revealed that YGB contained a variety of rare human saponins, such as Ginsenoside Rf, Ginsenoside F3, and Ginsenoside Rc. This was correlated with the ginsenoside species and content. The variation in fruit color was mainly affected by the cumulative content of flavonoids, anthocyanosides, and carotenoids, including red, pink, and reddish-purple [20]. In addition, the total flavonoids, total polysaccharides, and total polyphenols contents were high in RGB. The reason for this may be due to the influence of fruit color.

2.4. Evaluation of Red and Yellow Ginseng Berries’ Tyrosinase Inhibition Rate

Tyrosinase is a key enzyme in melanogenesis and a major factor in the enzymatic browning of fruits and vegetables [21]. Tyrosinase converts L-tyrosine to L-3,4-dihydroxyphenylalanine (L-DOPA), which is converted to dopaquinone, and then undergoes a series of reduction and oxidation reactions to become melanin [22]. The smaller IC₅₀ value represents the stronger tyrosinase inhibition ability of the sample. As shown in Figure 3, the IC₅₀ value of RGB was 21.09 mg/mL, and the IC₅₀ value of YGB was 14.67 mg/mL. The oxidative pathway of tyrosine to produce melanin can be blocked by ginsenosides Rb1 and Rg1, thereby reducing melanin production and contributing to skin-whitening effect. YGBs are more capable of inhibiting melanogenesis than RGBs, which may be related to the high content of ginsenosides in YGBs. The results of chemical composition identification revealed that YGBs contain rare ginsenoside Rg3, ginsenoside Rg2, and ginsenoside Rb2. Through RGB transformation, green ginseng berries are enriched with ginsenoside Rg2, which is more effective in inhibiting melanin production through the NF-κB pathway [23]. Ginsenoside Rb2 was effectively isolated from ginseng berries, which can be used as a potential whitening antioxidant to inhibit melanin synthesis in vivo and in vitro to achieve whitening efficacy [24].

2.5. Determination of HaCaT and B16-F10 Cell Activity by Red and Yellow Ginseng Berries

2.5.1. Screening of Red and Yellow Ginseng Berry Concentration and UVB Radiation Dose

As shown in Figure 4, cell survival showed a decreasing trend with increasing UVB radiation dose. The survival rate was lower than 50% at 500 mJ (p < 0.001), and 400 mJ was chosen for subsequent experiments. In Figure 4B–D, the two-fruit-colored samples acted on HaCaT and B16-F10 cells, respectively, and there was no significant difference in the range of 0–400 μg/mL (p > 0.05), with low cytotoxicity. Therefore, 50 μg/mL, 200 μg/mL, and 400 μg/mL of ginseng berries were selected for subsequent experiments.

2.5.2. Determination of Antioxidant Damage Capacity of Ginseng in Different Concentrations of Red and Yellow Ginseng Berry

SOD activity, MDA content, CAT activity, and GSH-P_X activity were determined according to the kit. The results are shown in

. Compared with the blank group, SOD activity, CAT activity, and GSH-P_X activity were significantly decreased in the UVB model group (p < 0.001); MDA content was significantly increased (p < 0.001). This revealed that UVB radiation induced oxidative stress in HaCaT cells, further indicating that the model was successfully modeled with significant differences. Compared with the model group, RGB and YGB were able to increase SOD activity, CAT activity, GSH-P_X activity (p < 0.001) and decrease MDA content (p < 0.001), showing a certain quantitative effect relationship, indicating that ginseng berries were able to reduce UVB-radiation-induced oxidative stress and possessed a significant capacity to resist oxidative damage. However, 400 μg/mL RGB had more potential antioxidant and anti-aging effects than YGB, and there was a significant difference between them.

2.5.3. Evaluation of Whitening Activity of B16-F10 Cells by Red and Yellow Ginseng Berries

In Figure 4O, there was a tendency for the relative content of melanin to decrease in all groups compared with the blank group of B16-F10 cells. The relative melanin content in the arbutin group amounted to 54.8 ± 0.5% (p < 0.001) compared with the blank group. The melanin content of B16-F10 cells in the 400 μg/mL RGB administration group was significantly reduced, and the relative melanin content amounted to 90.5 ± 1.7% (p < 0.001). The relative melanin content of B16-F10 cells in the 400 μg/mL YGB administration group reached 57.6 ± 1.2% (p < 0.001). This indicated that both RGBs and YGBs could significantly inhibit melanogenesis in B16-F10 cells in the concentration range of 50–400 μg/mL, and the inhibitory effects all showed a certain dose-dependence. At the same concentration, YGB had a significant difference (p < 0.001) compared with RGB, which was able to reduce melanin synthesis and had more whitening efficacy. Compared with the blank group, arbutin group showed a highly significant tyrosinase activity of 75.056 ± 2.846 (p < 0.001), the 400 μg/mL RGBs showed a tyrosinase activity of 84.545 ± 0.783, and the 400 μg/mL YGB showed a tyrosinase activity of 84.184 ± 2.240 (p < 0.001), and it decreased with the increase in concentration.

2.6. Evaluation of Anti-UVB Radiation and Whitening Efficacy of Red and Yellow Ginseng Berries in Zebrafish

2.6.1. Determination of Inhibition of UVB-Induced ROS Oxidative Damage in Zebrafish by Red and Yellow Ginseng Berries

It was observed that zebrafish embryos developed well at concentrations of 0–400 μg/mL. In this concentration range, zebrafish embryo matter survival was 100% and not teratogenic. The most commonly used method to detect intracellular ROS levels using fluorescent staining is the DCFH-DA fluorescent probe method [25,26]. Intracellular ROS are able to oxidize non-fluorescent DCFH, and the intensity of green fluorescence is proportional to the level of ROS [27]. Zebrafish fluorescence area was calculated by Image J. After induction with 400 mJ of UVB radiation, the fluorescence intensity of zebrafish in the model group was significantly higher than that of the blank group, indicating the success of photoaging modeling (p < 0.01); after intervention with the drug, the ROS began to diminish in the zebrafish. Compared with the model group, the rate of ROS generation was significantly lower in the drug-administered group, indicating that the ginseng fruit mitigated oxidative stress damage by inhibiting ROS formation in zebrafish larvae.

2.6.2. Evaluation of B16-F10-Cell-Whitening Efficacy by Different Concentrations of Red and Yellow Ginseng Berries

The developmental viability of zebrafish embryos at ginseng berry concentrations of 2.5–400 μg/mL had no toxic effects. As shown in Figure 4Q,R, the melanin content of zebrafish embryos was higher in the blank group, and all groups had a tendency to reduce the relative melanin content in vivo compared with zebrafish in the blank group. Compared with the blank group, the relative melanin content in the positive arbutin group amounted to 66.4 ± 1.1% (p < 0.001). Zebrafish embryos treated with RGB at a concentration of 400 μg/mL showed a significant decrease in melanin content, with the relative melanin content amounting to 77.5 ± 1.6% (p < 0.001). The relative melanin content of zebrafish embryos treated with YGB at a concentration of 400 μg/mL was 77.3 ± 1.0% (p < 0.001), which indicated that ginseng berries could significantly inhibit the melanogenesis of zebrafish. In addition, both RGB and YGB were able to inhibit the tyrosinase activity of zebrafish (p < 0.01). The 400 μg/mL YGB tyrosinase activity was determined as 87.370 ± 1.744, which was a highly significant difference (p < 0.001) compared with the blank group.

4. Conclusions

In this study, UHPLC-Q-Exactive MS combined with multivariate statistical analysis was used to identify and analyze the constituents of the two fruit colors of ginseng berries and identify the corresponding 31 differential compounds. The content of total ginsenosides in YGB was higher than that in RGB. Feruloyltartaric acid, Ovalitenone, and Garcimangosone D compounds were higher in RGB than in YGB. The in vitro antioxidant capacity assay revealed that RGB had more free-radical-scavenging capacity and better antioxidant activity. On the contrary, YGB had stronger in vitro tyrosinase inhibition than RGB. Total saponins were found to be higher in YGB than RGB by quantitative determination of constituents, and total flavonoids, total polysaccharides, and total polyphenols were higher in RGB than in YGB. Both ginseng berries were able to reduce the accumulation of lipid peroxides MDA; increase SOD content, CAT activity, and GSH-P_X activity; inhibit ROS levels; and effectively alleviate UVB-induced oxidative stress. Both ginseng fruits can reduce melanin content and inhibit tyrosinase production. In addition, zebrafish biology verified that RGB was superior to YGB in anti-aging skincare and YGB was superior to RGB in whitening skincare. This not only elucidates the chemical composition and skincare efficacy of the two berry colors of ginseng but also provides a basis for the cultivation and application of ginseng in later stages.
