摘要
本文对巴山松、马尾松和油松的木材和针叶的挥发性萜类进行了分析比较,共鉴定出60多种单萜、倍半萜、非萜烃类和一些酯类化合物。计算了各种样品间的相关系数和距离,结果表明巴山松在分类上与油松关系较接近。巴山松不论是木材精油还是针叶精油其中都以单萜成分占优势;木材精油中主要成分是α—蒎烯(最高含量达92％),并特含有脂肪酮;针叶精油主要成分可以是α—蒎烯(最高含量35％),也可以是石竹烯(最高含量30％)。马尾松木材精油中高含量的是长叶烯(20.51％);油松特含有广藿香烯。
Describes the chemotaxonoiny of P. henryi by comparison of its volatile oil components with, those of P. massoniana and P, tabulaeformis. The essential oil from needles and wood contain more than 60 components of monoterpenes, sesquiterpenes, non-terpene hydrocarbons and some esters and ketones. The correlation coefficients showed that P. henryi is more similar to P.tabulaeformis than P,massoniana. Differences were als foundo between chemical components of essential oils from wood and from needles of these pines. In either case, the major component of essential oil from wood is cx-pinene(up to 92%),and that from needles is either α-pinene (up to 35%) or cis-caryophyllene ( up to 30%) . The chemical components of essential oil from needles of P.henryi is reported for the first time.
