Analysis of Three Effective Components of Polyporus Umbellatus in Different Regions, Different Growth Periods and Different Harvest Periods
摘要
Abstract
The contents of ergosterol, ergosterone-4, 6, 8 (14) , 22-tetraen-3-one and polysaccharide of Polyporus umbellatus in different growth periods and different harvest periods were determined. The best regions, the best growth period and the best harvest period were obtained according to the difference in the content of different components. Ergosterol and ergosterone-4, 6, 8 (14) , 22-tetraen-3-one were determined by HPLC, and polysaccharides in P. umbellatus were determined by UV-vis, glucose as reference substance. The results showed that there were some differences in the contents of ergosterol, ergosterone-4, 6, 8 (14) , 22-tetraen-3-one and polysaccharides in different regions. The highest ergosterol of 1.41 mg/g is from Lincheng, Hebei. The highest ergosterone-4, 6, 8 (14) , 22-tetraen-3-one of 18.87 (g/g is from Luxi, Yunnan. The highest polysaccharides of 4.99％ is from Jilin. The contents of three components of P. umbellatus in Shaanxi are generally higher than those in other producing areas. In the same area (Lueyang, Shaanxi) , ergosterol, ergosterone-4, 6, 8 (14) , 22-tetraen-3-one and polysaccharides in P. umbellatus changed with the growth of the growth period. For the same growth period, the harvest time of P. umbellatus is appropriate in spring. This method is simple, sensitive and accurate. It provides scientific basis for finding the best place of regions, the best growth period and the best harvest period.关键词
