UNLABELLED
One of the major stored product pests, Indian meal moth causes the loss on the agriculture and food industries. This study was conducted to screen the insecticidal activity of ethanolic extracts and fractions partitioned by four different solvents [(1) -hexane; (2) ether; (3) ethyl acetate; (4) water] from star anise ( Hook. f.) against larvae. Among all solvent-partitioned fractions, the strongest repellency was found for the -hexane fraction of star anise extract. Solvent-solvent partitioning and chromatographic methods were further used to isolate and identify major anti-insect compounds from star anise extract. The results showed that -anethole (94.24%) was the major active compound showing an insect-repelling activity against . Consequently, -anethole can be utilized as a main natural insect-repelling agent for controlling the infestation.

印度谷螟是主要的仓储害虫之一，会给农业和食品工业造成损失。本研究旨在筛选八角茴香（Hook. f.）乙醇提取物及其用四种不同溶剂（(1) -己烷；(2) 乙醚；(3) 乙酸乙酯；(4) 水）分配得到的馏分对印度谷螟幼虫的杀虫活性。在所有溶剂分配馏分中，八角茴香提取物的 -己烷馏分表现出最强的驱避性。进一步采用溶剂分配和色谱方法从八角茴香提取物中分离和鉴定主要的抗虫化合物。结果表明，反式茴香脑（94.24%）是对印度谷螟表现出驱避活性的主要活性化合物。因此，反式茴香脑可作为控制印度谷螟虫害的主要天然驱避剂。
