千斤拔的品种调查与质量研究

A Survey on the Varieties of Flemingia (Flemingia) and Comparison of Their Respective Quality

对千斤拔的品种调查表明，蔓性千斤拔、大叶千斤拔和宽叶千斤拔是当前的主流品种。经对３种千斤拔的药材性状，组织结构，化学成分预试，ＴＬＣ、ＵＶ比较，以及浸出物、总黄酮含量测定，急性毒性与药效学试验，结果表明３者所含成分大致相似，药理作用无明显差异。

Result of the survey showed that Flemingia philippinesis Merr. et Rolfe, F. macrophylla (Willd ) Prain and F. latifolia Benth. were the main varieties under current usage. Results from the comparative studies on their pharmacognostic characteristics, tissue structure, preliminary chemical compositions tests, TLC and UV spectra of crude drugs, quantitative analysis of total flavones in water extracts, acute toxicity and pharmacodynamics showed that their compositions and pharmacologic effects are essentially similar without obvious differences. Therefore, they may have the same value in medical practice.
