“…Using essential oils extracted from some medicinal herbs and food plants, Aumeeruddy-Elalfi et al [22] demonstrated a minimal anti-collagenase activity and anti-elastase activity of 52.2% inhibition at 400 µg/mL and 32.23% inhibition at 800 mg/mL, respectively. A methanolic extract of water-pepper sprout inhibited collagenase activity in a concentration-dependent manner with an IC 50 value of 156.7 µg/mL [23].…”

The phenol content of vegetable oil and its antioxidant activity are of primary interest for human health. Oilseed species are considered important sources of these compounds with medicinal effects on a large scale. Total phenol content (TPC) and antioxidant activity (AA) of safflower oil were previously studied. Nevertheless, there is no report on genotypic differences and antiaging activity of safflower oil. The aim of this study was to determine the TPC, diphenyl-picrylhydrazyl (DPPH), and antiaging activity on three respective accessions from Syria, France, and Algeria of seed oil of safflower grown under semi-arid conditions during 3 consecutive years (2015, 2016, and 2017). The results showed that phenol content as well as antioxidant and antiaging activity varied according to both genotype and years. In 2017, the mean value of TPC in oil seed was two times higher than in 2015 and 2016. Moreover, accessions presented different TPC values depending on the year. The highest antioxidant activity was observed among accessions in 2017 compared to 2015 and 2016. As expected, a positive correlation was found between TPC and antioxidant activity. The inhibition in the collagenase assay was between 47% and 72.1% compared to the positive control (83.1%), while inhibition in the elastase assay of TPC ranged from 32.2% to 70.3%, with the positive control being 75.8%. These results highlight the interest of safflower oil as a source of phenols with valuable antioxidant and antiaging activity, and uses for cosmetics.

“…In a previous study, N ‐ trans ‐caffeoyltyramine ( 8 ) was reported to exhibit 2,2‐diphenyl‐1‐picrylhydrazyl radical scavenging and low density lipoprotein oxidation suppression activities 69 . A previous report confirmed that quercetin 3′‐galactopyranoside ( 10 ) is effective toward the suppression of collagenase activity 70 . Therefore, 3 , 8 , and 10 are considered to be worth using as photoaging improvement materials.…”

To investigate the phytochemical constituents of Hibiscus hamabo, a chromatographic method was used. A new phenolic glucoside, woodorien A (1), along with 10 known compounds, rutin (2), isoquercetin (3), nicotiflorin (4), astragalin (5), trans-tiliroside (6), N-trans-feruloyltyramine (7), N-trans-caffeoyltyramine (8), woodorien (9), quercetin 3 0 -galactopyranoside (10), and cis-tiliroside (11), was isolated. The structure of 1 was identified as ethyl 3-O-β-D -glucopyranosyl-4-hydroxybenzoate. Compounds 8, 9, and 11 were isolated from genus Hibiscus, and 2-7 and 10 were isolated from H. hamabo for the first time. Their chemical structures were determined through the interpretation of spectroscopic data. The properties of the UVA photoaging induction assay of all isolated compounds were measured. Compounds 3, 8, and 10 exhibited recovery from photoaging induced by UVA in CCD-986sk. These results suggest that H. hamabo is a potential source of natural antiphotoaging ingredients and can be used in cosmetic applications.

Abstract. Pozdnyakova Y, Omarova G, Murzatayeva A, Tankibaeva N. 2022. Biodiversity of wild spice plants of the Central Kazakhstan region and their medicinal potential. Biodiversitas 23: 4609-4625. The Central Asian region stretches from the Caspian Sea in the west to the border of western China in the east. Central Kazakhstan occupies the space of steppe and semi-desert zones within the Turgay Plateau in the west and the Kazakh Uplands in the center and in the east. Due to the remoteness of the steppes of Central Kazakhstan from the oceans, the climate in the region is extremely continental and arid. Due to this, the diversity of plant species is quite small. In this work, we have studied the biodiversity of wild herbs growing in the climatic conditions of Central Asia. We also assessed the prospects of the found plant species as medicines. This study took place as part of the traditional summer practice of biology students in the period July-August 2019. The main method used in the field research was route reconnaissance. As a result of field research, 40 wild spice plant species belonging to 17 families were found. Among them, the most numerous are the families Lamiaceae - 9 species, Brassicaceae - 6 species, Apiaceae - 5 species, Asteraceae - 4 species, the families Rosaceae and Fabaceae - 2 species of herbs. All of these species are mentioned in a number of old recipes and can be revived and re-recommended for widespread use. A critical assessment of the literature on the medicinal properties of the studied spices irrefutably shows that they have enormous health potential. Based on the data obtained, it can be concluded that wild spice plants growing in the territory of Central Kazakhstan have a wide range of taste diversity and prospects for successful commercial exploitation.
