Ketumpangan air (Peperomia pellucida (L.) Kunth), an Indonesian wild plant, is commonly found in every Indonesian region with moist shady place. People usually consume ketumpangan air as a fresh vegetables. Empirically, ketumpangan air is consumed to treat fever, stomach disease, kidney disorders, drug abscesses, boils acne, headaches, pain in arthritic and rheumatic gout, or other external treatment. In this research, we tested the acute toxicity of ethanol extract from ketumpangan air using experimental animals mice DDY strain. We also tested the Brine Shrimp Lethality Test (BSLT) using Artemia salina Leach larva shrimp. The main aim of this reseach was to determine the LD50 and LC50 values of ethanol extract from Ketumpangan air. The results showed that the ethanol extract was categorized as ‘mild toxic’. The calculation of LD50 with Reed and Munich method showed that the LD50 value for male and female group was 15.13 g/ kg and 11.87 g/kg respectively. The BSLT result showed that the LC50 values of Ketumpangan air was 81.28 ppm.

Ethanol extract of Syzygium cumini (jamblang) leaves reveal its significant α-glucosidase inhibitory activity which perform the potential activity of this plant extract as antidiabetic agent. However, other bioactivities of this plant extract have been reported. The aim of current study was to evaluate the comparison of in vitro antidiabetic, antioxidant and cytotoxic activity of S. cumini fractions. The S. cumini leaves ethanol extract was fractionated by using column chromatography with n-hexane, ethyl acetate and methanol as eluents. Seven fractions were obtained from column chromatography (F1-7). The results showed that the best antidiabetic activity was found in F5 (93% α-glucosidase inhibitory activity), the best antioxidant activity was found in F4 (83% inhibition of DPPH free radical) and the best cytotoxic activity was found in F2 (69% growth inhibition of T47D breast cancer cell line). Therefore besides in vitro antidiabetic activity, fractions of S. cumini leaves ethanol extract also showed antioxidant and cytotoxic activities. Since the results showed that the most active fractions for antidiabetic, antioxidant and cytotoxicity were differed, it could be possible to isolate the different potential active compounds for each activity.Keywords : Syzygium cumini, α-glucosidase inhibitor, DPPH, cytotoxicity
