Special Issue Information

Dear Colleagues,

Plant extracts, for the most part, are compound extracts of the polyphenol group, most widely represented by flavonoids. Laboratories worldwide have developed many modern types of extraction methods, one of the most gentle and green methods of plant and food matrix extraction at present being supercritical CO2 extraction.

Flavonoids are secondary metabolites, mainly consisting of a benzopyrone ring bearing phenolic or polyphenolic groups at different positions. They are most commonly found in fruits, herbs, stems, cereals, nuts, vegetables, flowers and seeds. The presence of bioactive phytochemical constituents in these different plants grants them medicinal value and biological activity.

Flavonoids have been used in natural dyes, cosmetics, skin care products and antiwrinkle skin agents, with the most pronounced application of these polyphenols, however, being in the field of medicine. Flavonoids have been used extensively as anticancer, antimicrobial, antiviral, antiangiogenic, antioxidant, neuroprotective, antitumor and antiproliferative agents, also capable of preventing cardiometabolic disorders and displaying a better preservation of cognitive performance with aging.

Blue honeysuckle (Lonicera caerulea L.) bears dietary fruits that are rich in bioactive compounds. However, information on the metabolome profiles of honeysuckle varieties grown in Russia is limited. In this study, we employed tandem mass spectrometry to study the metabolome profiles of four L. caerulea varieties (Volhova, Tomichka, Goluboe vereteno, and Amfora) grown in two geographical locations in Russia, i.e., the Russian Far East and St. Petersburg. We observed that the metabolome profiles of the four varieties grown in two locations differ significantly, particularly in the polyphenol’s other compound classes. We were able to identify 122 bioactive compounds in extracts from honeysuckle berries, 75 compounds from the polyphenol group and 47 compounds from other chemical groups. Thirty chemical constituents from the polyphenol group (flavones jaceosidin, cirsiliol, sophoraisoflavone A, chrysoeriol-O-hexoside, flavonols dimethylquercetin-3-O-dehexoside, rhamnocitrin, rhamnetin II, stilbenes pinosylvin, resveratrol, dihydroresveratrol, etc.) and twenty-seven from other chemical groups were identified. The largest number of unique polyphenols is characteristic of the variety Tomichka, the selection of the regional state unitary enterprise “Bakcharskoye”, from the free pollination of L. caerulea, originating in the Primorsky Territory of Russia (L. caerulea subspecies Turczaninow). This genotype has the highest number of similar unique polyphenols, regardless of where it was grown. Blue honeysuckle genotypes originating from Primorsky Krai in Russia can be used in various breeding programs in order to improve and enrich the biochemical composition of fruits. It should also be noted that, regardless of the place of cultivation, the total amount of unique polyphenols remains quite large. Attention should be paid to the Volhova honeysuckle variety, obtained through gamma irradiation of the Pavlovskaya variety (Kamchatka ecotype). This sample is characterized by a stable composition of biologically active substances, regardless of the growing area. These data could support future research on the production of a variety of pharmaceutical products containing ultrapure extracts of L. caerulea. Full article

In the current study, the ethanolic extract of the stem bark of Ceiba speciosa, the silk floss tree (SFSB), was evaluated against various phytopathogenic microorganisms, including Ralstonia solanacearum, Dickeya solani, Pectobacterium atrosepticum, P. carotovorum, Fusarium oxysporum, and Rhizoctonia solani. At 300 µg/mL concentration, the SFSB extract exhibited the highest inhibition percentages of 83.33 and 86.67 for R. solani and F. oxysporum, respectively. In addition to its antimicrobial activity, SFSB extract exhibited strong antioxidant activity (IC50 value of 140.88 g/mL). HPLC analysis of the extract revealed the presence of various phenolic acids and flavonoids. Among these compounds, naringenin (18,698.83 µg/g), chlorogenic acid (2727.49 µg/g), ferulic acid (1276.18 µg/g), syringic acid (946.26 µg/g), gallic acid (812.34 µg/g), and methyl gallate (651.73 µg/g) were found to be the most abundant constituents. GCMS analysis showed that there were antimicrobial compounds like terpenoids, benzoic acid derivatives, phthalate esters, and different fatty acids. Isopropyl myristate was the most common compound, with a relative abundance of 55.61%. To our knowledge, this is the first investigation on the phytochemical composition and antimicrobial properties of SFSB extract. Consequently, utilizing SFSB extract could hold significant potential as a sustainable and natural approach for controlling and mitigating plant diseases. Full article
