This study aimed to evaluate the antioxidant potential and fatty acid profile of gabiroba (Campomanesia xanthocarpa Berg) seeds. In order to obtain the extract, the seeds were dried, crushed, and subjected to sequential extraction by maceration and percolation in a modified soxhlet extractor using solvent polarity gradient composed of hexane, chloroform, ethyl acetate, and alcohol, respectively. The extraction time was six hours. The ethanol extract showed the highest antioxidant potential, given by the EC50 value and the amount of total phenolic compounds. High amounts of unsaturated fatty acids were found in the oil studied, especially the oleic acid.

Family Lamiaceae (labia) includes a large number of cosmopolitan speciesincluding Thymus alpestris (Thyme) characterized by the presence of essential oilsand phenolic compounds. It represents a perennial semi-shrubby plant. Theantioxidant potential of thyme is due to the presence of polyphenolic acids andflavonoids. The topic of this paper is the extraction of thyme (Thymus alpestris)with 40% ethanol and 50% ethanol, using Soxhlet method (circulatoryextraction), after which, the content of phenolics and flavonoids was determinedin order to confirm the antioxidant potential of this plant species. The resultsshow that 40% ethanol extract has the highest content of phenolics andflavonoids and the highest antioxidant potential, resultingly.

The present study aimed to study the anti-oxidant potential of isolated flavonoids from the ethanol extract (70%v/v) of Cassia tora leaves. Three flavonoids were isolated viz Luteolin-7-O-β-glucopyranoside (I), quercetin-3-O-β-d-glucuronide (II) and Formononetin-7-O-β-D-Glucoside (III) from the ethanol extract (70%v/v) of Cassia tora leaves in the previous study. A comprehensive study on the phytochemical contents - total phenolic content and flavonoid content was accessed using Folin-Denis and AlCl3 method respectively. The antioxidant potential of the samples was evaluated using inhibition of hydroxyl radical, 2,2-diphenyl-1-picrylhydrazyl (DPPH), and nitric oxide scavenging methods. The total phenolic content and flavonoid content was found to be 18.60 % w/w and 9.5% w/w respectively. The IC50 values of ethanol extract against hydroxyl, DPPH and nitric oxide radical were found to be 270 µg/mL, 190 µg/mL and 130 µg/mL respectively. The radical scavenging activity of the isolated flavonoids decreased in the following order: quercetin (IC50 values 15, 14, 18 µg/mL) >formononetin (IC50 values 19, 21, 14 µg/mL) > luteolin (IC50 values 20, 23, 18 µg/mL) respectively.

Agar Dilution

Plants have been used for centuries to treat various diseases. In this study, Marrubium globosum Montbret & Aucher ex Benth. plant was used as a material. The extract of the plant was extracted with the help of soxhlet device using ethanol, which is a good polar solvent, and Rel Assay kits were used to determine the oxidant and antioxidant levels in the plant extract. Antifungal and antibacterial activities of M. globossum were tested against standard bacteria and fungus strains by agar dilution method. As a result of the analysis, TAS value of plant extract was determined as 7.677±0.231, TOS value as 12.387±0.083 and OSI value as 0.162±0.004. In this context, it has been observed that the plant has an important antioxidant potential. In addition, the plant extract was found to be effective against test microorganisms at 50-200 μg/mL extract concentrations. As a result, it has been determined that M. globossum can be a natural antioxidant and antimicrobial source.

Skin Moisture

Green mustard plants can be formulater into peel-off masks to moisturize the skin, because based on previous research green mustard leaves cointain flavonoids as antioxidants which can moisturize the skin. The purpose of this study was to find out green mustard leaves can be formulated into peel-off mask preparations and to find out the preparation and to find out the preparation off peel off mask with etanol extract of green mustard leaves can moisturize the skin. This study uses an experimental method. Green mustard leaves are extracted by maceration. In this study, a skin analyzer was usee as a mesure of skin moisture level after using peel off mask from a variety of dosage formulations which were divided into 5 preparations, blank (without mask, 3%,4%,5%), postive control (using peel off masks on the market). The Anova test results show a sig value of 0,000 or p<0,005 so it is concluded that the variabel has a difference. The conclusion of this study proves that the ethanol extract of green mustard leaves can be used as a peel-off mask for skin moisturizer, where the higher the concentration of mustard leaf extract, the higher the moisture vlue of the skin.
