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 the contents of four kinds of polysaccharide in Rhizoma Polygonatum from different regions in Yunnan Province. Methods: The samples of Rhizoma Paridis planted in walnut forests in different areas of Yangbi of Yunnan were collected and determined according to the methods contained in the Chinese Pharmacopoeia 2015 edition. Results: There were significant differences in the contents of four kinds of polysaccharide from the reed of Reichenza officinalis in different regions of Yunnan. The samples were all downloaded from Imitation Wild Plantation, but the length of cultivation was different. Among them, the contents of four kinds of Apatosychus fortunei in Rhizoma Paridis grown from 4 to 5 years old were significantly higher than that of 3-year-old Rhizoma Paridis. CONCLUSION: There are significant differences among the four samples of Saponin content related to the ecological environment, growth period and the genetic background among different populations of the same species.
