Abstract

One type of Bajakah that is believed by local people especially in the area of Muara Badak, KutaiKertanegara Regency, has the efficacy of anticancer drugs, is Uncaria nervosa Elmer. The purposes of this studywere to determine the content of secondary metabolites and the toxicity of the extracts of the bark and root of thewood of Bajakah (U. nervosa). From the results of phytochemical tests showed that both bark and root woodcontain secondary metabolites of alkaloids, flavonoids, terpenoids, and phenolics. Moreover, based on the result ofthe mortality test for Artemia salina shrimp larvae, it showed that both the bark and wood of the roots are verytoxic with LC50 values of 1.76 and 2.66 ppm, respectively. Both of these extracts are potentially cytotoxic to cancercells.

Abstract

Phytochemical test and antibacterial activity of Macaranga lamellata Whitmore have been done. This research aims to find out the secondary metabolites using Thin Layer Chromatography (TLC) and to determine antibacterial activity by paper disc method from methanol extract on Macaranga lamellata Whitmore leaf. Based on the results obtained from phytochemical tests, it was known that methanol extract contains alkaloid, flavonoid, polyphenol and terpenoid/steroid compounds. Antibacterial activity obtained Minimum Inhibitory Concentration values from methanol extract for Streptococcus sobrinus KCCM 11898 and Salmonella typhi ATCC 422 at 0-0.5%.
