Bioactive Compounds of Mansoa alliacea Leaf Extract has Potential as Botanical Pesticides to Control Colletotrichum acutatum against Anthracnose Disease on Chili Pepper

Bioactive compounds of Mansoa alliacea leaf extract has potential as botanical pesticides to control Colletotrichum acutatum against anthracnose disease on chili pepper was be done. Base on in vitro test on PDA with inhibition zone diameter of 28 mm, but it is not certain bioactive compounds. For these problem, the aim is research is conducted to determine the content of bioactive compounds of Mansoa alliacea leaf extract to potentially as botanical pesticides . The method used for analysis of bioactive compaounds as column chromatography and thin layer, and GCMS. Base on phytochemicals test the extract of Mansoa alliacea containing 4 secondary metabolites are terpenoids, alkaloids, flavonoids, and phenols. Result analysis using GCMS there are 4 active compound namely pentan-1,3-dioldiisobutyrate, 2,2,4-trimetyl; tributyl acetylcitrate; terephthalic acid, di(2-ethylhecyl) ester and 2,6,10,14,18,22-tetracosahexaene, 2,6,10,15,19,23-hexamethyl. Based on the existing references, of 4 compounds and 3 of them have been known as antifungal compounds. Those are pentan-1,3-dioldiisobutyrate, 2,2,4-trimetyl; tributyl acetylcitrate; terephthalic acid, di(2-ethylhecyl) ester.
