目的利用GC-MS分析技术鉴定雪峰虫草中的挥发性成分。方法采用Rxi-5MS（30 m×0.25 mm,0.25μm）弹性石英毛细管柱;以高纯He气（纯度99.999%）为载气,进行程序升温;质谱定性以EI电离方式采集数据;根据NIST质谱数据库推测雪峰虫草的物质成分。结果分别从雪峰虫草的石油醚部位中鉴定了44个化合物;从雪峰虫草的乙酸乙酯部位中鉴定了28个化合物。两部位的主要化合物类型为酸类、酯类以及甾醇类,石油醚和乙酸乙酯部位的相对含量分别占78.5%和77.36%。结论首次采用GC-MS方法对雪峰虫草两部位的挥发性成分进行对比分析,以期为雪峰虫草的物质基础研究提供参考。

Objective To identify the volatile constituents from Ophiocordyceps xuefengensis by GC-MS. Methods The separation was performed on a Rxi-5MS (30 m×0.25 mm, 0.25 μm) with high purity He gas (purity 99.999%) by temperature programmed chromatograph. Electron Ionization EI source was applied. The structure of material composition was speculated by the Mass spectrometry database (NIST). Results 44 compounds were elucidated from the petroleum ether portion of Ophiocordy-ceps xuefengensis, 28 compounds were elucidated from the ethyl acetate portion ...
