摘要: 生物活性筛选试验表明,菊科植物猪毛蒿(Artemisia scoparia Waldst. Et Kitag)全草精油具杀虫活性。采用GC-MS方法分析了猪毛蒿精油的化学成分。共检出92个成分,鉴定了其中46个成分。通过柱层析分离出主成分,经各种波谱分析鉴定为1-苯基-2,4-己二炔。活性跟踪结果表明,l-苯基-2,4-己二炔为猪毛蒿精油中的主要杀虫成分。

关键词: 猪毛蒿, 精油, 杀虫活性, 1-苯基—2, 4-已二炔

Abstract: The insecticidal activity of the essential oil from Artcmisia scoparia (Asteraceae)against Sitophilus zeamais was determined. By means of GC-MS analysis, 92 constituents were separated from the essential oil and 46 of them were identified. The predominant component of the essential oil was isolated and identified to be l-phenyl-2,4-hexadiyne which was found to be responsible for the insecticidal activity of the essential oil.

Key words: Arternisia scoparia——essential oil——insecticidal activity——l- phenyl-2, 4-hexadiyne
