Analysis on Fingerprint Chromatogram of the Volatile Oils Obtained from Asarum Heterotropoides with Different Methods

Zeng Hong-yan

Abstract

The paper analyzed the GC-MS fingerprint chromatograms of the volatile oils obtained with supercritical CO_2 , microwave and stream distillation from Asarum heteroroupoides. The compounds from the volatile oils extracted with supercritical CO_2 and microwave are resemble. The oil by stream distillation is different from the two formers. Methyl eugenol is a characteristic constituent of the oil gained, its content is higher in the oils with the three methods. The volatile oil obtained with supercritical CO_2 is natural. Supercritical CO_2 extraction is ideal for extracting the volatile oils.
