Abstract

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.

摘要

在对榄香脂属植物对抗台湾乳白蚁的拒食化合物的持续研究中，从榄香脂属植物提取物中分离得到了 6-去乙酰宁比林（1）、槲皮素（2）和杨梅素（3）。所有化合物均通过 NMR 和 MS 进行了表征。此外，通过 X 射线晶体学确定了 6-去乙酰宁比林的结构。通过非选择性摄食试验评估了拒食活性。在 0.5mg 剂量下，6-去乙酰宁比林在分离出的化合物中表现出最高的拒食活性。
