[Objective] The study aimed to compare the content of total polysaceharides, saponins and flavone in different parts of D. Rhombi-folia. [Method] The total polysaccharide, saponins and flavone content in different parts of A rhombifolia were determined by UV-visible spectrophotometer. [Result] The total polysaccharides content in different parts were as follows; 30.19% in fruits, 4.86% in seeds, 5.28% in stems, 28.43% in leaves and 16. 78% in roots. The total saponins contents in different parts were 4. 73% in fruits, 1. 33% in seeds, 6.64% in stems, 6.24% in leaves and 3.26% in roots. The total flavone content in different parts were 4.20 mg/g in fruits, 2.01 mg/g in seeds, 3. 60 mg/g in stems, 23.16 mg/g in leaves and 8.26 mg/g in roots. [ Conclusion] The order of total polysaccharides, saponins and flavone content in different parts were fruits > leaves > roots > stems > seeds, stems > leaves > fruits > roots > seeds and leaves > roots >fruits > stems > seeds,respectively.%[目的]比较老鸦柿不同部位总多糖、总皂苷和总黄酮的含量.[方法]采用比色法测定总多糖、总皂苷和总黄酮的含量.[结果]不同部位总多糖的含量分别为:果实30.19％、种子4.86％、茎5.28％、叶28.43％、根16.78％；不同部位总皂苷的含量:果实4.73％、种子1.33％、茎6.64％、叶6.24％、根3.26％；不同部位总黄酮的含量:果实4.20 mg/g、种子2.01 mg/g、茎3.60 mg/g、叶23.16 mg/g、根8.26 mg/g.[结论]总多糖含量为果实＞叶＞根＞茎＞种子；总皂苷含量为茎＞叶＞果实＞根＞种子；总黄酮含量为叶＞根＞果实＞茎＞种子.
