CHEMICAL COMPOSITION AND ANTIOXIDANT ACTIVITITES FROM ETHYL ACETATE EXTRACT OF MORINDA OFFICINALIS COLLECTED IN DAK LAK
Keywords:
Morinda officinalis, GS-MS, ethyl acetate, antioxidant activity, Dak LakAbstract
Morinda officinalis is a species of herbal plant belonging to the genus Morinda L., the coffee family (Rubiaceae), this species is widely distributed in the northern mountainous provinces, the Central Highlands and the province China's Guangxi. Currently, Morinda officinalis is propagated and grown in Dak Lak province and is used as a medicine. In this study, we determined the chemical composition of ethyl acetate root extract and evaluated the antioxidant activity of the extract obtained by DPPH method.
The results of determining the chemical composition of the ethyl acetate extract have 15 compounds, the main classes of which are: anthraquinones, triterpenes, organic acids. Evaluation of high oxidizing mineral activity of ethyl acetate extract by DPPH method showed very strong antioxidant capacity with IC50 = 3.33 mg/ml, 10.5 times stronger than ascorbic acid positive control (IC50 = 34.99 mg/ml).
