摘要

In the continuing study of antifeedant compounds in Protium javanicum Burm. f. against Coptotermes formosanus Shiraki, 6-desacetylnimbin (1), quercitrin (2) and myricitrin (3) were isolated from P. javanicum extract. All compounds were characterised by NMR and MS. Furthermore, the structure of 6-desacetylnimbin was confirmed by X-ray crystallography. The antifeedant activity was evaluated with no-choice feeding tests. At a dose of 0.5 mg, 6-desacetylnimbin exhibited the highest antifeedant activity among the isolates.
