Analysis of Volatile Constituents of Chinese Medicinal Herbs by Flash Distillation--Capillary Gas Chromatography-Mass Spectrometry (Ⅱ)

In present work, the volatile constituents of Chinese medicinal herbs, therhizomes of Alpinia officinarum Hance, the peel of the fruit of Orange havebeen analyzed by means of flash distillation/capillary gas chromatography/massspectrometry. The results obatined were similar to that of ordinary methodsof steam distillation-extraction. The conditions of flash distillation have beenstudied. These experimental results proved that such a method was a promis-sing tool for analysis of volatile constituents of natural products. Its main fea-tures were quick performance, simple manipulation and micro quantity of bio-logical sample used.
