Title : Antifeedant activity of some pentacyclic triterpene acids and their fatty acid ester analogues.
Year : 2003
Volume : 51
Issue : 7
First Page : 1952
Last Page : 1955
Authors : Mallavadhani UV, Mahapatra A, Raja SS, Manjula C.
Abstract : The 3-O-fatty acid ester derivatives (C(12)-C(18)) of two pentacyclic triterpenic acids, ursolic acid and oleanolic acid, were synthesized under mild esterification conditions in excellent yields (80-85%) and screened for their antifeedant activity, together with the parent acids, against the agricultural pest tobacco caterpillar larvae (Spodoptera litura F) in a no-choice laboratory study. The Urs-12-ene-28-carboxy-3beta-octadecanoate and olean-12-ene-28-carboxy-3beta-hexadecanoate were found to exhibit exceptionally potent antifeedant activities at 50 microg/cm(2) concentration, even after 48 h.
Antifeedant activity against fourth-instar larval stage of Spodoptera litura reared on castor leaves assessed as decrease in food consumption at 150 ug/cm2 after 48 hr by no-choice leaf disk assay relative to untreated control
