Abstract:
Cordyceps gunnii (Berk.) Berk. is one of the important species of Cordyceps spp, which has similar constituents and pharmacological activities to the traditional Chinese medicine Cordyceps sinensis. In the paper, the extraction and separation of vitamin E from Cordyceps gunnii (Berk.) Berk. were studied using 30%, 50%, 80% ethanol solution and ethyl acetate. The content of the crude vitamin E was analyzed with thin layer chromatography (TLC) and UV spectrophotometer methods. The results showed that the higher the organic solvent content in the extracting solution, the higher the content of vitamin E and the lower the purity of the vitamin E. Besides, ethyl acetate was shown to be the best organic solvent for the extraction of vitamin E from Cordyceps gunnii.
