美味猕猴桃茎的生药鉴别

Pharmacognostic Studies on the Stem of Actinidia deliciosa C.F.Liang et A.R.Ferguson

目的利用生药学研究,为美味猕猴桃茎的鉴别和开发利用提供科学依据。方法粉末制片法、石蜡切片法、紫外吸收光谱法、薄层色谱法。结果性状特征:中柱鞘有纤维与石细胞共存,韧皮部有较多分泌细胞、乳汁管和筛管散在;粉末中可见较多木纤维和韧皮纤维。理化鉴别特征:乙醇浸液在212.5 nm处有最大吸收,氯仿浸液在246.0,412.5 nm处有最大吸收。结论所得结果可作为美味猕猴桃茎的鉴别依据。

Objective To provide a scientific basis for identification and utilization of the stem of Actinidia deliciosa C. F. Liang et A.R. Ferguson. Methods Powder slide paraffin sectionslide, UV, TLC were used. Results Microscopic characteristics： in stem transverse, fibers and stone cells were found in pericycle. Secretory cells,milk vessel and sieve tube were found in phloem. There were many phloem fibers and xylem fibers in powder. UV： Ethanolic extract of stem had a absorption peak at 212.5 nm, chloroformic extract of stem had two absorption peaks at 246.0,412.5 nm. Conclusion The results can be taken as the reference for identification of the stem.
