苦玄参苷类成分的积累动态研究
Study on dynamic accumulation of glycosides in Picria f elterrae
摘要
Abstract
The content of glycosides of P. felterrae in different growth period were detected with HPLC to reveal its dynamic accumulation. The correlation analysis of glycosides and the growth situation was conducted throught comparing the chromatograms and peak areas of different growth period. The results showed that the variation trend of content of glycosides, picfeltarraenin IA and Ptarraenin IB was nearly consistent. The content of picfeltarraenin IA and Ptarraenin IB both reached to the maximum when the plant grew up to 75 days, then subsequently decreased slowly,but increased again in early fruit stage(namely 120d)when the biomass reached to the maximum. Therefore, it was suggested that the best collection stage for P. felterrae was the early fruit stage(120 d).关键词
