Abstract

Phytochemical test and toxicity in ethanol extract, ethyl acetate fraction and residual ethanol fraction of ajeran leaves (Bidens pilosa L.) has been done. The method used to determine secondary metabolites is clualitative test and the value of Lethal Concentration (LC50) with the Brine Shrimp Lethality Test (BSLT). Phytochemical test results showed that the ethanol extract and ethyl acetate fraction contained flavonoid, steroid and phenol compound. Residual ethanol fraction contained flavonoid and phenol compound. Toxicity test showed ethanol extract had LC50 value of 862.19 ppm. Ethyl acetate fraction has LC50 value of 8.26 ppm. Residual ethanol fraction had LC50 value of 275.24 ppm. The results of the toxicity test can be concluded that the ethyl acetate fraction very toxic category, ethanol extract and residual ethanol fraction included toxic category. The results that obtained from GC-MS characterization were steroid

Abstract

The test of amylase inhibition activity of the leaves of Melicope lunu-ankenda and bark of Melicope glabra (BI.) T.G. Hartley extracts were done. The objective of this study was to determine in-vitro α-amylase inhibition activity against two samples by DNS method. The result showed that two samples of Melicope lunu-ankenda leaves and bark of Melicope glabra (BI.) TG Hartley displayed the enzyme inhibitory effect with percent inhibitions of 48.71% and 46.36%. Two sample extracts can inhibit amylase. It can be suggested that about sample were potential as antidiabetic agents.
