Green grass jelly (Cyclea barbata Miers.) is known for its benefit to human health especially in supporting body’s immune system and wellness. This research aimed to determine immunomodulatory and antioxidant activity of green grass jelly leaf extracts in vitro. Old leaves were collected as sample then dried and ground to powder. The extraction was done with sohxletation using three different solvents, chloroform, ethyl acetate, and ethanol. The immunomodulatory activity was evaluated by treating the crude extracts at concentrations of 50, 100, and 500 mg/mL on macrophages of rat in vitro. The

In the present study, two microbial ethyl acetate extracts from Streptomyces were tested for their antifungal properties against Thielaviopsis paradoxa, the causal organism of stem bleeding disease in coconut. The cultural filtrates of 2 strains of Streptomyces (AFL-1 and AFL-2) were extracted with Ethyl acetrate. The resulting ethyl acetate extract of AFL-1 showed complete in-vitro inhibition of fungal growth at relatively low concentrations (0.25%) while Ethyl ecetate ext
