Abstract:

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

Objective: This study was aimed to assess the phytoconstituents, cytotoxic, and antioxidant efficacy of ethyl extract of Cleome gynandra leaves.Methods: Qualitative phytochemical analysis with different solvent extracts was performed. Quantitative and gas chromatography-mass spectrometry (GC-MS) analysis of the extract was performed with ethyl acetate extract. The cytotoxic effect of the ethyl acetate extract was determined by 3-[4,5-dimethylthiazol-2-yl]2,5-diphenyltetrazolium bromide (MTT) assay on Michigan Cancer Foundation-7 (MCF-7) cells using taxol as standard and free radical scavenging
