Abstract

The essential oils from leaves and inflorescences of Hyptis martiusii Benth were analyzed by GC-MS. Twenty-six compounds representing 93.2% of the essential oil of leaves were characterized; Delta-3-carene (22.5%), 1,8-cineole (24.27%), beta-caryophyllene (6.15%), and bicyclogermacrene (6.32%) were found as the major components. In the essential oil of inflorescences 27 compounds representing 87.7% of the oil were identified. The major components were Delta-3-carene (13.5%), alpha-pinene (5.78%), beta-caryophyllene (6.59%), viridiflorene (8.25%), and germacrene B (5.21%). The essential oil of leaves and 1,8-cineole showed pronounced insecticidal effect against Aedes aegypti larvae and Bemisia argentifolii, the vectors of dengue fever and white fly fruit plague, respectively.

摘要

采用气相色谱-质谱联用（GC-MS）技术对马蒂氏香科叶草（Hyptis martiusii Benth）叶片和花序的精油进行了分析。鉴定出了占叶片精油93.2%的26种化合物；发现主要成分有Δ-3-蒈烯（22.5%）、1,8-桉叶素（24.27%）、β-石竹烯（6.15%）和双环吉马烯（6.32%）。在花序精油中，鉴定出了占该精油87.7%的27种化合物。主要成分有Δ-3-蒈烯（13.5%）、α-蒎烯（5.78%）、β-石竹烯（6.59%）、绿叶烯（8.25%）和吉马烯B（5.21%）。叶片精油和1,8-桉叶素分别对埃及伊蚊幼虫和银叶粉虱（登革热和粉虱果瘟的传播媒介）显示出显著的杀虫效果。
