✦ Synopsis

Various extractdfractions of the whole plant of Convolvulus microphyllus (Convolvulaceae) were bioassayed by the leaf disc method for feeding deterrence using Spilosoma obliqw Walker as a test insect. A new compound, 29-oxodotriacontanol isolated from the chloroform fraction of this plant was proved to be a potent antifeedant constituent under laboratory evaluations, whereas another compound, tetratriacontanoic acid was reported for the first time from this plant. The azadirachtin and crude neem extracts were taken as standard. A new compound (29-oxodotriacontanoI) produced 85.74% inhibition at SO00 ppm concentration.
