Abstract
In our continuing programme of screening Sri Lankan plants for
insecticidal activity. plant extracts are screened at Peradeniya and at Basle,
Switzerland and where activity is observed, bioactivity directed fractionation is
undertaken to isolate the active Compound.
Our work on Ag/aia apiocarpa, a Meliaceae growing in the Knuckles
range led to the isolation of a cyclopentanotetrahydrobenzofuran rocaglamide which
showed high insecticidal and herbicidal activity. Studies on a more common species
of Ag/aia, A.e/aeagnidea showed it to contain roclagamide as well as four other
related compounds of high activity. These compounds have shown activity against a
wide range of insect> at low concentration and represent the best results of our
screening programme so far.
Extracts from this plant could be used for pest control by Sri Lankan
farmers and the activity of the compounds themselves indicate that they have the
potential for commercial exploitation by the plant protection industry.
