西洋参的植物化学研究概况。从安大略、魁北克、缅因州、佛蒙特州和威斯康星州的野生种群收集的北美人参（North American ginseng）进行。反相高效液相色谱法被用来确定的水平的自然变化的三七皂苷Rg 1，Re，Rf，Rb 1，Rc，Rb 2，和Rd和他们的总叶，茎，根的真实野生生长的材料。根中的总含量为1 - 16%，最大数量的个体样品具有4-5%的总皂苷。在真正的野生种群的根中缺乏的CITR-Rf证实了其作为区分美国人参和亚洲人参的植物化学标记的地位。收集了10个地理上孤立的野生种群，其中几个种群的主要皂苷水平存在显着差异。在4年生时，野生和栽培的五叶参根的平均总黄酮含量没有统计学差异，表明野生工艺没有植物化学理由。本文报告的野生西洋参总黄酮含量的基线数据为质量保证计划提供了参考水平。
A survey of the phytochemistry of Panax quinquefolius L. (North American ginseng) collected from wild populations in Ontario, Quebec, Maine, Vermont, and Wisconsin was undertaken. Reverse-phase HPLC was used to determine the natural variation of levels of ginsenosides Rg1, Re, Rf, Rb1, Rc, Rb2, and Rd and their total in leaf, stem, and root of authentic wild-grown material. The totals in roots varied from 1 to 16%, with the greatest number of individual samples having 4-5% total ginsenosides. The lack of ginsenoside Rf in roots of authentic wild populations confirmed its status as a phytochemical marker differentiating American and Asian ginseng. Ten geographically isolated wild populations were collected, and several showed significant variation in the levels of major ginsenosides. There was no statistical difference in mean ginsenoside content between wild and cultivated P. quinquefolius roots at 4 years of age, suggesting there is no phytochemical justification for wild crafting. Baseline data on total ginsenoside levels for authentic wild P. quinquefolius reported here provide reference levels for quality assurance programs.
