目的:充分利用中藥鉤藤的植物資源,測定并比較大葉鉤藤UncariamacrophyllaWall.的葉和鉤莖中的表兒茶素含量。方法:利用RP-HPLC測定。結果:鉤藤鉤莖中含表兒茶素0.38%,葉中含0.82%。結論:大葉鉤藤中含有較多的表兒茶素,葉中含量大于鉤莖中含量

Epicatechin content in Uncaria macrophylla Wall. was determined by RP HPLC As a result, the epicatechin contents were 0 38% in the hook and stem, and 0 82% in the leaf Thus it seemed to be more worthwhile to produce epicatechin from the leaf rather than from the hook and stem
