[Influence of different cultivation measures on chemical quality of Codonopsis Radix].

ABSTRACT

To observe the influence of different cultivation measures on the chemical constituents of Codonopsis Radix and provide reference for its reasonable cultivation, Codonopsis Radix samples cultivated by different cultivation measures were collected from the planting base in Min county,and their quality were evaluated by establishing HPLC fingerprint and determining the content of lobetyolin and Codonopsis Radix polysaccharide. The results show that different cultivation measures have an effect on the quality of Codonopsis Radix and the contents of lobetyolin and Codonopsis Radix polysaccharide are obviously different. According to the content of lobetyolin, not using Zhuanggenling>using Zhuanggenling. While, not pinching, shelving>not pinching, not shelving>pinching, shelving>pinching, not shelving. According to the content of Codonopsis Radix polysaccharide, not using Zhuanggenling>using Zhuanggenling. While, not pinching, shelving>not pinching, not shelving>pinching, not shelving>pinching, shelving. Based on the chemical quality evaluation results, the appropriate cultivation measure of Codonopsis Radix is not using Zhuanggenling, not pinching and shelving.
