摘要(Abstract):

该研究利用HPLC对不同产地黄芪4种异黄酮成分(毛蕊异黄酮葡萄糖苷、芒柄花苷、毛蕊异黄酮、芒柄花素)含量进行测定,并通过灰色关联度分析和通径分析探究气候因子对黄芪异黄酮成分含量的影响。结果表明,不同产地黄芪异黄酮类成分含量差异具有统计学意义(P<0.05);灰色关联分析显示,7月最高温度、1月最低气温和日均温对黄酮苷类成分含量影响较大,降水量和相对湿度对黄酮苷元类成分是较为重要的影响因子;通经分析显示,1月份最低气温和海拔对黄芪中4种异黄酮类成分含量的直接正效应较大;高海拔和极端温度条件可能更不利于黄芪异黄酮类成分的积累,因此,"高异黄酮型"黄芪生产应选择1月最低气温较高的低海拔区域。该研究为黄芪药材质量评价提供参考依据,同时为黄芪适宜生境选择、种植标准建设以及精准药材定向培育等提供基础研究资料。
In this study, HPLC was used to determine the content of the four isoflavones of Astragalus membranceus var. mongholicus from different regions(calycosin-7-glucoside, ononin, calycosin and formononetin), and gray correlation analysis and path analysis were used to explore the influence of climate factors on the content of isoflavone components in A. membranceus var. mongholicus. The results showed that there were significant differences in the content of the four isoflavones in different areas(P<0.05); grey correlation analysis showed that the highest temperature in July, the lowest temperature in January and the daily average temperature had a greater impact on the content of flavonoid glycosides, meanwhile precipitation and relative humidity were the more important factors for the accumulation of flavonoid aglycones. According to the general analysis, the direct positive effects of the lowest temperature in January and altitude on the contents of four isoflavones in A. membranceus var. mongholicus were significant. High altitude and extreme temperature conditions might be more adverse to the formation and accumulation of isoflavone components. Therefore, the religions of A. membranceus var. mongholicus with high contents of isoflavones should be chosen the low altitude region with higher minimum temperature in January. This study provides a reference basis for the quality evaluation of A. membranceus var. mongholicus, and basic data for the selection of suitable habitat, construction of planting standards and directional cultivation of medicinal materials in A. membranceus var. mongholicus.
