Garcinia cowa Roxb is a plant used as traditional medicine containing antioxidant activity. Plant extracts with antioxidant activity are often used as bioactive ingredients in anti-aging cosmetics. Studies on bioactive compounds and the use of this plant in cosmeceuticals have yet to be widely reported. This study aims to determine and analyze the levels of flavonoids, vitamins C, and vitamin A in G. cowa fruit flesh extract. These three compounds are bioactive ingredients that are beneficial in reducing the symptoms of photoaging on the skin. The G. cowa used in this study was obtained from Tampunik Kambang, Pesisir Selatan Regency, and was extracted by maceration method using 96% ethanol. The testing of vitamin C levels in the extract of G. cowa fruit flesh was carried out through High-Performance Liquid Chromatography (HPLC) method using a UV detector with a wavelength of 264 nm. Quantitative HPLC analysis was carried out based on the resulting peak area data from the chromatogram. Vitamin A and flavonoid levels were measured using ultraviolet-visible spectrophotometry (UV-VIS) at maximum wavelengths of 286 and 429 nm. The results show that the levels of vitamin C and vitamin A in G. cowa was 151.4 mg/100g extract and 1.23 g 100g extract, while the flavonoid level was 69.5 mg/100g extract. The level of vitamins C, vitamin A, and flavonoids in G. cowa can contribute to natural bioactive substances and can be developed further into anti-aging cosmeceutical products.
Acne vulgaris is a skin disease caused by inflammation of the polysebaceous follicles (skin oil glands). Acne, if left untreated, can lead to depression and a crisis of confidence for the sufferer. Acne vulgaris can occur at any age due to several factors, one of which is food. This study aimed to analyze the level of acne vulgaris, determine the consumption pattern of fast food, and the relationship between fast food and the incidence of acne (acne vulgaris) in students. This type of research is analytic with a cross-sectional approach. The research sample was 52 people using a consecutive sampling method. Data analysis used univariate analysis and bivariate analysis with a chi-square test. The results showed that the highest acne vulgaris was in the moderate category, namely 23 people (44.2%). Fast food consumption patterns were in a bad category, namely 22 people (42.3%), so there was a relationship with a significance value of 0.018 < 0 0.05 between fast food consumption behavior and the incidence of acne (acne vulgaris) in students. It was concluded that the highest incidence of acne (acne vulgaris) was in the moderate category, and the highest consumption pattern of fast food was in the bad category. There was a positive and significant relationship between fast food consumption behavior and the incidence of acne (acne vulgaris) in college students.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
