Skrining Fitokimia dan Uji Aktivitas Antibakteri Ekstrak Benalu Duku (Loranthus Sp)

Abstract

It had done the experiment of phytochemical screening, the antibacterial activity of ethyl acetate extracts by lanseh parasite leaf (Loranthus Sp). The powder of lanseh parasite leaf is extracted maceration using methanol to produce as much as 50 g of methanol extract, methanol extract is diluted with ethyl acetate and ethyl acetate extracts produced as much as 20 g. Based on phytochemical screening of the methanol extract contains coumponds by alkaloids, flavonoids, terpenoids and tannins, while on the ethyl acetate extract containing flavonoids. Against the ethyl acetate extract obtained antibacterial activity test performed by disc diffusion method with a concentration of 10%, 20%, 30%, 40%, and as a comparison is used DMSO. The test results ethyl acetate extracts showing activity in distinct inhibition against the growth of bacteria Escherichia coli and Staphylococcus aureus. The ethyl acetate extract with a concentration of 20%, 30%, 40% were able to inhibit the growth of Staphylococcus aureus 9.3 mm, 10.3 mm, 10.7 mm but the bacteria Escherichia coli not show any inhibition zone in bacteria.
