摘要(Abstract):

目的 :研究我国野生延胡索种质资源的现状及其质量。方法 :调查野生延胡索种质资源的分布状况 ,并用HPLC法测定其中主要 6种生物碱含量以评价其质量。结果 :野生延胡索主要分布于长江中下游两岸的丘陵地区 ,其分布区在不断地缩小、消失 ,不同居群之间生物碱含量差异较大。结论 :野生延胡索种质在生物碱含量上表现出较高的生物多样性 ,有些种质的主要生物碱含量很高 ,是延胡索良种选育的材料 ;它们具有较强的繁殖能力 ,但处在自然淘汰的进程中 ,必须加以的保护。
Objective: To study the resource and the quality of wild Corydalis yanhusuo distributed in China. Method: Distribution was observed and samples of wild C. yanhusuo were collected and qualities were evaluated by determining six main alkaloids contained in the samples. Result: The main distribution of wild Corydalis yanhusuo was in the hills around middle and lower reaches of Yangtze River. Its distributive areas were continuously decreasing. The alkaloids contents in the samples varied among different populations. Conclusion: The alkaloids contents in wild populations of C. yanhusuo are diverse. The main kinds of alkaloids in some wild populations are higher than cultivated ones, which are valuable for breeding. The wild C. yanhusuo propagate well, however they are endangered due to environment problem, and should be protected.
