Chem ical Evaluation of Germplasm Resources of Paris Polyphylla var. Yunnanensis in Yunnan and Guizhou / 中国药师

ABSTRACT

Objective:To screen fine germplasm resources and suitable cultivated place for Paris polypyh lla var.yunnanensis by determining the content of total saponins , total flavonoids and total polysaccharides collected from Yunnan and Guizhou .Methods:An Ultraviolet-visible spectrophotometry method was applied to determine the total contents of saponin , flavonoid and polysaccharide in 14 germplasm resources of Paris polyhp ylla var.yunnanensis.Results:The contents of saponins, flavonoids and polysaccharides in Paris polyphylla var.yunnanensis collected from the different habitats were obviously different .The herb with high quality was selected from Xiaguan and Dali with the highest total content of saponins and the content of the three components was 55.760 0 and 61.632 0 mg· g-1 , respectively , which was significantly higher than that from the other habitats .Conclusion: It is proved that the quality of Pa ris polyphyll a var.yunnanensis produced in Dali of Yunnan is better than that from the other regions , and the high yield culture techniques should be studied further .
