摘要
运用气相色谱对在温室栽培的Hymenaea courbaril和Copaifera officinalis及C. pubiflora幼树叶内倍半萜类化合物昼夜和季节性变化进行了分析测定。Hymenaea和Copaifera这二个属植物叶内具有基本相同的一组倍半萜类化合物,对认为具有生态意义的它的主要成分:石竹烯(caryophyllene),α,β-瑟林烯(selinene)和树脂含量进行了分析统计。在三个季节和昼夜的资料中,这二个属植物的石竹烯、α,β-瑟林烯和树脂含量昼夜变化是很小的,而在植株间(遗传型)和不同的季节里它们有明显而有意义的变化。
Leaf sesquiterpene hydrocarbons of greenhouse-grown saplings of Hymenaea courbaril, and Copaifera officinalis and C, pubiflora were analyzed by GC for seasonal and diurnal variation. Of the suite of essentially the same ses-quiterpenes in leaves of both genera, only the major compounds (caryophyllene and a , β-selinene) and total quantity (yield) were analyzed statistically as they were considered most likely to be of ecological significance. Diurnal variation was minimal in both Hymenaea and Copaifera during the three: dates sampled. Both individual tree (genotype) and seasonal variation were different at highly significant levels for caryophyllene, selinene and yield in both Hymenaea and Copaifera. This study was supported in part by U. S. National Science Foundation.
