摘要
目的研究茯苓的挥发性成分。方法利用有机溶剂-水蒸气蒸馏提取茯苓挥发性成分,用GC-MS进行分离测定,结合计算机检索技术对分离化合物进行结构鉴定,应用色谱峰面积归一化法计算各成分的相对百分含量。结果茯苓超微粉中分离出131个成分,鉴定出67个化学成分,占挥发油总量的51.145%,其中相对百分含量大于2%的分别确定为壬醛Nonanal 2.058%;樟脑Camphor 2.401%;2,3-二甲基萘烷2,3-dimethyl Decalin 3.819%;反橙花叔醇trans-Nerolidol 2.266%;金合欢醇Farnesol 3.322%;α-柏木醇α-Cedrol 7.936%。结论首次报道利用简便的有机溶剂-水蒸气蒸馏法提取茯苓超微粉挥发性成分。
Objective To study the chemical constituents of the volatile oil from Poria cocos. Methods The chemical compositions of the volatile oil obtained by organic - team distillation with hexane were analyzed by GC - MS. The constituents were identified by their mass spectra. The relative percentage of the oil constituents was calculated from the GC peak areas. Results One hundred and thirty - one kinds of chemical constituents in micro - milling of Poria Cocos were separated ; of which sixty - seven compounds representing 51. 145% of the oil were characterized. Relative contents that were more than 2% were determined as Nonanal 2. 058% , Camphor 2. 401% ,2,3 - dimethyl Decalin 3. 819%, trans - Nerolidol 2. 266% , Farnesol 3. 322% , α - Cedrol 7. 936%. Conclusion This paper reports, for the first time, the composition of volatile oils of micro - milling of Poria Cocos obtained by organic - teams distillation with hexane.
