Abstract

Essential oils from the heartwood and leaves of specimens of Vanillosmopsis pohlii collected in two different localities were analyzed by GC-MS. The major constituent of both heartwood essential oils was the sesquiterpene alpha-bisabolol. Essential oil composition from leaves was quite different for two specimens and showed beta-pinene and E-caryophyllene as principal constituents. The essential oil of heartwood and the pure sesquiterpene alpha-bisabolol were tested against Bemisia argentifolii, the white fly fruit plague, and pronounced insecticidal effects were observed.

摘要

采用气相色谱 - 质谱联用（GC-MS）分析法，对采集于两个不同地点的波氏香荚兰（Vanillosmopsis pohlii）标本的心材和叶片中的精油进行了分析。两种心材精油的主要成分均为倍半萜α-红没药醇。两个标本叶片的精油成分差异较大，主要成分显示为β-蒎烯和反式石竹烯。对心材精油和纯倍半萜α-红没药醇针对银叶粉虱（Bemisia argentifolii）（即粉虱果瘟）进行了测试，观察到了显著的杀虫效果。
