STANDARDIZATION OF SPECIFIC PARAMETERS OF CITREH (Cymbopogon citratus) ETHANOL EXTRACT AS A NATURAL ANTIOXIDANT

Antioxidants can prevent damage caused by excessive exposure to free radicals, such as ultraviolet light and air pollution. Lemongrass is known to contain flavonoids, saponins, phenols, alkaloids, and steroids, which are compounds that have antioxidant activity. The antioxidant content of lemongrass allows to be developed into cosmetic, herbal, insect repellent, and essential oil products. Standardization of components of secondary metabolic compounds is very important; this will be used as a guide or parameter in determining compounds and raw materials later in product development. In order to obtain a standardized product. The development of cymbopogon citratus extract has started in recent years, one of which is product development, namely insect repellent and essential oil. Parameters for determining standardized citronella raw materials will produce standard compounds in relation to being active ingredients in a product. Standardization of extract parameters will play an important role in determining the final result or influencing the antioxidant activity of the product to be produced. The specific parameters that will be carried out later will focus more on the phytochemical test for levels of secondary metabolites from the kitchen lemongrass and will increase the selling value of the cymbopogon citratus. The IC50 value of the ethanol extract of cymbopogon citratus is 71.96 ppm, or it has a strong category. Phytochemical test results extract of cymbopogon citratus contains alkaloids, flavonoids, phenolics, tannins, and saponins.
