Abstract

The chemical composition of the essential oils from aerial parts of Pectis apodocephala and Pectis oligocephala were analyzed by GC-MS. The essential oils of these species were predominantly constituted by monoterpenes. Geranial (42.9-44.5%), neral (32.2-34.2%) and alpha-pinene (10.7-11.4%) were the main constituents in the oil of P. apodocephala, while p-cymene (50.3-70.9%) and thymol (24.4-44.7%), were the prevalent compounds in the oil of P. oligocephala. The essential oils were tested against the root knot nematode Meloidogyne incognita and Aedes aegypti larvae survival. The results obtained show that both essential oils exhibited significant activity and could be considered as potent natural namaticidal and larvicidal agents.

摘要

采用气相色谱 - 质谱联用（GC - MS）法分析了无头笔花豆（Pectis apodocephala）和少头笔花豆（Pectis oligocephala）地上部分挥发油的化学成分。这些物种的挥发油主要由单萜类化合物组成。香叶醛（42.9 - 44.5%）、橙花醛（32.2 - 34.2%）和α - 蒎烯（10.7 - 11.4%）是无头笔花豆挥发油中的主要成分，而对伞花烃（50.3 - 70.9%）和百里香酚（24.4 - 44.7%）是少头笔花豆挥发油中的主要化合物。对所得挥发油进行了抗根结线虫南方根结线虫（Meloidogyne incognita）和埃及伊蚊幼虫存活试验。结果表明，两种挥发油均表现出显著活性，可被视为有效的天然杀线虫剂和杀幼虫剂。
