Study on the Appropriate Collection Period of Polygonatum sibiricum in Guizhou

SHAO Hong-yan et al(Institute for Drug Control of Southwest Guizhou Province,Xingyi,Guizhou 562400)  
[Objective]The research aimed to study the the appropriate collection period of Polygonatum sibiricum in Guizhou.[Method] Taken the rootstalk of P.sibiricum from GAP experiment demonstration base of P.sibiricum in Fenggang County of Guizhou Province for materials to make crude drug and processed product.And then the polysaccharide contents were determined.[Result]The results showed that,the appropriate collection period of P.sibiricum in Zunyi was December to the next January.And four-year-old seed reproduction P.sibiricum was the appropriate harvest period,with polysaccharide content of 39.54%and the drying rate of 36.64%.[Conclusion]The appropriate collection period of P.sibiricum had been determined,and it was meaningful to provide safe,stable and effective medicinal materials of P.sibiricum according to GAP principle.
