云南漾濞不同地区核桃林下种植重楼的重楼皂苷含量比较

Comparison of Polyphyllins Content in Paris Polyphylla Planted under Walnut Forest in Different Areas of Yunnan Yangbi

目的：对云南漾濞不同地区核桃林下栽种重楼中的4种重楼皂苷含量进行比较。方法：采集云南漾濞不同地区核桃林下栽种的重楼样品，按中国药典2015年版收载的方法进行含量测定。结果：云南漾濞不同地区栽种重楼中4种重楼皂苷含量各样品间存在显著差异。样品均为仿野生林下载培，但载培时间长短不一，其中生长年限4-5年的重楼药材中4种重楼皂苷含量明显高于3年生重楼。结论：4种重楼皂苷含量各样品间存在显著差异与重楼生长的生态环境、生长年限和同一物种不同居群间遗传背景等不同有关。

Objective： To compare 4 polyphyllins contents in Paris polyphylla planted under walnut forest in different areas of Yun- nan Yangbi. Methods： Paris polyphylla samples planted under walnut forest were collected in different areas of Yunnan Yangbi, and according to the methods described in Chinese Pharmacopoeia （2015 edition）, the contents were determined. Results： Yunnan Yangbi different planted in Paris polyphylla four polyphyllins content of each sample there were significant differences between samples were cultivated in imitation of the wild forest, but the cultivation of varying lengths of time, the growth period of 4 to 5 years in Paris polyphylla four polyphyllins content was significantly higher than that of 3 born in Paris polyphylla. Conclusion： Four kinds of Paris polyphylla saponin content of the samples have significant differences with the Paris polyphylla growth of ecological environment, growth period and the same species living on different populations, the genetic background.
