HPLC法测定采光方式对穿龙薯蓣薯蓣皂苷、原薯蓣皂苷含量的影响

目的:探讨穿龙薯蓣无支架、树枝支架、木杆支架和网状支架等不同采光结构对药材质量的影响,从而确定适宜栽培方法。方法:HPLC法测药材中薯蓣皂苷、原薯蓣皂苷含量。结果:薯蓣皂苷、原薯蓣皂苷总含量分别是3.04%、3.95%、5.33%和4.86%,而野生穿龙薯蓣含量为4.04%。质量提高与光照强度增加有关。结论:网状支架提高穿龙薯蓣的质量,为其他藤本类药材栽培提供良好借鉴。

This study aimed to explore the effect of lighting frameworks such as non--shelf,branch--shelf, stick--shelf and network-- shelf on quality of Chinese medicine from Dioscorea nipponica,a perennial twisted herbal liana. Methods：Determine the contents of the dioscin and protodioscin by HPLC. Results：The total contents of the dioscin and protodioscin were 3.04%,3.95%,5.33% and 4.86% respectively, but content from the wild was 4.04%,indicating that the drug quality on the light intensity.Conclusion：The increase of quality through network--shelf can offer good use for reference for other twining vine cultivation.
