Objective:
To research the germplasm resources and the contents of senegenin in processing products of Polygala tenuifolia.
Method:
The contents of senegenin in wild Polygala tenuifolia and cultivated samples of Polygala tenuifolia were determined by RP-HPLC, and compared.
Result:
The contents of senegenin in wild reduce gradually along Shaanxi, Shanxi, Hebei to Dongbei. The contents of senegenin in cultivated three-year samples of three year Polygala tenuifolia from five main place was similar, 0.44%-0.49%. The content of senegenin were 0.44%-0.64% in the wand and 0.03%-0.09% in the residual part of stem, and the content of senegenin in Polygala tenuifolia was more than that in processing products.
Conclusion:
There is a correlation between the content of senegenin in Polygala tenuifolia and ecology environment that show a is inverse proportion with the quality grade, and the contents in the processing products were decreased. Senegenin can be used as a characteristic marker in range. This research provides a reference for search a index for quality control of Radix polygala and its processing products.
