酢浆草显微鉴别的专属性研究

Specificity Research on Microscopic Identification of Oxalis corniculata

目的:探索酢浆草显微鉴别的专属性,为其进一步研究提供鉴别依据。方法:以红花酢浆草为对照,用常规的显微技术观察不同产地、不同海拔的酢浆草的组织构造和显微特征。结果:不同产地、不同海拔的鲜品酢浆草的横切面显微特征很相似,但与鲜品红花酢浆草的横切面显微特征差异较为明显;不同产地、不同海拔的酢浆草粉末显微特征无明显差异,与红花酢浆草的差异也不明显。结论:鲜品酢浆草的横切面显微鉴别特征专属性较强,可以作为鲜品酢浆草的显微鉴别依据,但将酢浆草粉末显微特征作为鉴别依据值得商榷。

Objective： Explore the microscopic identification of Oxalis corniculata specificity for the further research and to provide evidence for identification. Method： With safflower O. corymboas as control, using conventional microscopy techniques to observe the organizational structure and microscopic characteristics of the O. corniculata from different origins and different elevations. Result： The fresh O. corniculata cross-sections microscopic characteristics from different origins and different elevations are similar, but O. corymboas cross- sections microscopic characteristics with fresh safflower is obvious different; microscopic characteristics of O. corniculata powder from different origins and different elevations had no obvious difference, and with safflower O. corymboas differences are also not obvious. Conclusion： The microscopic features of cross-section of fresh O. corniculata have strong specificity, which can be used as microscopic identification basis for fresh O. corniculata, but microscopic characteristics of O. corniculata powder as a basis for identification will be questionable.
