本文研究了泽漆根茎挥发油对小鼠的触杀和驱避活性。史密斯（菊科）对香烟甲虫（Lasiserricorne）进行了评价。水蒸气蒸馏法提取的挥发油经GC-FID和GC-MS分析，其主要成分为泽漆酮（40.2%）、α-香芹烯（8.6%）、环氧蛇麻烯II（7.3%）、异香烯（5.9%）和小茴香烯（4.7%）。莪术酮及其类似物占挥发油总量的60.3%。结果表明，挥发油对L. serricorne成虫，LD 50值为48.3 µg/成虫。α-香紫苏烯（LD_（50）= 13.1 μg/成虫）对L. serricorne高于氧化蛇麻烯（LD 50 = 31.2 µg/成人）、β-香芹烯（LD 50 = 35.5 µg/成人）和zerumbone（LD 50 = 42.4 µg/成人）。α-香芹烯处理2 h和4 h后，其驱避活性分别为78.63 nL/cm ~ 2和V级。结果表明，玉米酮及其类似物有可能开发成为防治烟草甲的天然杀虫剂或驱避剂，但其生物活性受其结构的影响。
The contact toxicity and repellent activities of the essential oil extracted from the rhizomes of Zingiber zerumbet (L.) Smith (Zingiberaceae) was evaluated against cigarette beetles (Lasioderma serricorne). The essential oil obtained by hydrodistillation was investigated by GC-FID and GC-MS. The main constituents of the essential oil were zerumbone (40.2%), α-caryophyllene (8.6%), humulene epoxide II (7.3%), camphene (5.9%) and fenchene (4.7%). Zerumbone and its analogues totally are accounting for 60.3% of the essential oil. It was found that the essential oil possessed contact toxicity against L. serricorne adults with a LD50 value of 48.3 µg/adult. α-Caryophyllene (LD50 = 13.1 µg/adult) exhibited stronger contact toxicity against L. serricorne than humulene oxide (LD50 = 31.2 µg/adult), β-caryophyllene (LD50 = 35.5 µg/adult) and zerumbone (LD50 = 42.4 µg/adult). Moreover, α-caryophyllene possessed strong repellent activity (Class IV and V, respectively) against the beetles at 78.63 nL/cm2, after 2 and 4 h treatment. The results indicate that zerumbone and its analogues might be developed into natural insecticides or repellents for control of cigarette beetles, but their bioactivities are affected by their structures.
