摘　　要：对不同产地大血藤的不同营养器官的总鞣质、总生物碱、皂苷、木质素、绿原酸、总黄酮共6种次生代谢产物的含量进行测定与比较。结果显示:6种次生代谢产物在不同营养器官中的含量具有一定的差异,总含量以叶最高,老茎次之,幼茎最小。6种次生代谢产物除木质素茎含量较高外,其余5种均以叶片的含量最高,差异具有显著性。不同产地大血藤的6种次生代谢产物的含量具有显著性差异。通过逐步回归分析和通径分析,得知大血藤叶片次生代谢产物与土壤生态因子的关系密切。聚类分析显示庆元百山祖及天台的大雷山和天台山的大血藤叶片的次生代谢产物含量较高。The contents of 6 secondary metabolism such as tannin, alkaloid, saponin, lignin, chlorogenic acid and flavonoids in different organs of Sargentodoxa cuneata from different producing areas were determined and compared. The results showed that there were certain differences among the contents of 6 secondary metabolism in different organs of S, cuneata. The total content of 6 secondary metabolism was the highest in the leafblades, and that in stem was the second while that in root was the lowest. The content of lignin in stem and root was relatively higher than that in leafblades, while the contents of other 5 secondary metabolism in the leafblades were the highest （the difference is significant）. There were also significant differences among the contents of 6 secondary metabolism in S. cuneata from different producing areas. Stepwise regression analysis and path analysis indicated that the contents of 6 secondary me- tabolism were nearly correlated with the soil ecological factors. Through systematic cluster, it was concluded that the contents of secondary metabolism were higher in the leaves from Baishanzu Mountain in Qinyuan County, Daleishan and Tiantaishan in Tiantai County.
