Abstract


This study was to determine the fruit maturity level of wild bitter gourd and the composition of water extract which is effective as antifeedant and appropriate for mortality test on armyworm larvae. Results obtained show that water extract of wild bitter gourd fruit contains phenolic compounds, flavonoids and triterpenoids. Terpenoid compounds contained in water extract of fruits at maturity level 4H, 8H and 12H were momordicoside L, momordicoside K, compound 3β, β7, 25-trihydroxycucurbita-5.23(E)-diena-19-al:R1=H, R2= H and momordicine 1.Fruit maturity level 4H 50% and 4H 60% resulted to the highest antifeedant index, ie 40.08% and 44.20%.LC50at fruit maturity level 4H observed on day 7 was 40%.
