ABSTRACT
To study the dynamic change law of bioactive constituents from Polygonum multiflorum, and to explore the optimal harvest period of P. multiflorum. Determination of stilhene glucoside, anthraquinones and catechin from P. multiflorum in different harvest times by MEKC-DAD, and principal component analysis (PCA) was used to comprehensive evaluation for bioactive constituents. There are obvious differences among the contents of active ingredients in various collecting periods samples, the content of stilbene glucoside was the highest in November, the total content of combined anthraquinone was the highest in November and December, the content of catechin was the highest in September. The comprehensive evaluation index obtained with principal component analysis showed that the sample collected in November is significantly higher than those with other samples. The optimal harvest period of P. multiflorum is November.
