【摘要】 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。更多还原

【Abstract】 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.更多还原
