Abstract

The potential allelopathic activity of devil's-claw [Proboscidea louisianica (Mill.) Thellung] essential oil and a few of the compounds it contains on the elongation of cotton (Gossypium hirsutum L.) and wheat (Triticum aestivum L.) radicles was studied using a Petri dish bioassay. Essential oil was collected by steam distillation using an all-glass-Teflon assembly. Ether extracts of the steam distillates from fresh devil's-claw were inhibitory to cotton and wheat radicle elongation. The following six components of devil's-claw essential oil identified by CGC-MS-DS were inhibitory to cotton and/or wheat at a concentration of 1 mM: vanillin, piperitenone, δ-cadinene,p-cymen-9-ol, α-bisabolol, and phenethyl alcohol.

摘要

采用培养皿生物测定法研究了钩状棘豆（Proboscidea louisianica (Mill.) Thellung）精油及其所含的几种化合物对棉花（Gossypium hirsutum L.）和小麦（Triticum aestivum L.）幼根伸长的潜在化感活性。精油通过全玻璃-特氟隆组件的蒸汽蒸馏收集。新鲜钩状棘豆的蒸汽馏出物的乙醚提取物对棉花和小麦幼根伸长有抑制作用。通过 CGC-MS-DS 鉴定的钩状棘豆精油的以下六种成分在 1mM 浓度下对棉花和/或小麦有抑制作用：香草醛、胡椒酮、δ-杜松烯、对伞花烃-9-醇、α- 倍半萜醇和苯乙醇。
