Abstract

In Dak Lak, there is a bitter eggplant currently used as food. In Vietnam, there are presently very few studies on this eggplant species compounds and biological effects. The research aims to isolate several of compounds according to their antioxidant effects using the DPPH method. Based on the initial research results, five compounds were isolated from the ethyl acetate extract and their antioxidant activity was determined using the DPPH assay: propyl gallate (IC₅₀= 13,57 µg/mL), protocatechuic acid (IC₅₀ = 15 µg/mL), caffeic acid (IC₅₀ = 17,63 µg/mL), astragalin (IC₅₀ = 256,51 µg/mL), 5-O-caffeoylquinic acid (IC₅₀ = 20,97 µg/mL) (IC₅₀= 13.57 µg/mL). For the first time, the compounds of the Bitter Solanum plant (Solanum incanum L.) have been determined. The above research results have added more information, improving the valuable use and direction of further research on this species in Vietnam.
