| 中文摘要： | 目的：分析济源地区野生品系冬凌草中的挥发性成分。方法：采用顶空固相微萃取（HS-SPME）法对河南省济源地区43种野生冬凌草地上部分中的挥发性成分进行提取，采用气相色谱-质谱联用（GC-MS）法检测成分，采用面积归一化法计算各成分的相对含量。结果：43种野生冬凌草挥发性成分的种类和相对含量具有明显差异，种类在0～11种之间，相对含量在0～84.03％之间；石竹烯、石竹烯氧化物、二氢猕猴桃内酯、植酮和百秋李醇在多种不同品系野生冬凌草的挥发性成分中存在，是其主要成分；其挥发性成分的主要结构类型由萜烯类、酮类、醇类和酯类组成，此外在个别品系冬凌草中还含有少量的脂肪酸类，如棕榈酸、油酸和亚油酸。结论：济源地区不同品系野生冬凌草内在质量存在一定差异。 |
| 英文摘要： | OBJECTIVE：To analysis the volatile components in wild strains of Rabdosia rubescensin in Jiyuan area. METHODS： Headspace solid phase microextraction （HS-SPME） was conducted to extract the volatile components in 43 wild species of R. rubescens， GC-MS was conducted to identify the components， and peak area normalization method was conducted to calculate the relative content of the components. RESULTS：The variety and relative contents of the volatility components in 43 wild species had obvious differences and the ranges of species number and relative content was from 0 to 11 and from 0 to 84.03％ respectively. Caryophyllene， caryophyllene oxide， dihydroactinidiolide， phytone and patchouli alcohol were main components which existed in a variety of different strains of volatile components of R. rubescens，and were mainly composed of terpenes， ketones， alcohols and esters. In addition，fatty acids such as palmitic acid， oleic acid and linoleic acid were contained in a few individual varieties. CONCLUSIONS：The internal quality in 43 wild species of R. rubescens has certain differences. |
