摘要
目的:为了更有效地鉴定中药独活并作为该药材标准化的基础,我们对其详细的形态和显微特征进行了深入的研究。方法:从独活的道地产区收集药材样本,并采用传统的生药学鉴定手段对其形态和显微特征进行研究并与文献进行了比较。结果:发现了一种明显的但一直被忽视的粉末新特征,即具有交错纹理的纺锤形薄壁细胞,可作为一个重要的鉴定独活药材的显微特征。此外,本文对其形态及其它显微特征及文献的异同分别进行了描述和探讨。结论:这些结果为完善独活的药材鉴定提供了重要的科学依据。
Objective: In order for effective authentication of Radix Angelicae Pubescentis and to establish a basis of the herb standardization, the detailed morphological and microscopic characteristics were investigated. Methods: Samples were collected from the representative producing areas of China; the conventional pharmacognostic techniques were adopted for trait description and micro- scopic identification, which were finally compared with those reported. Results : A distinct and previously neglected new feature for the identification of the powdered crude drug, which was the spindle-shaped parenchymatous ceils with crisscross striation, was identified and shown as an important microscopic characteristic for herb authentication. In addition, other microscopic features were also described in details and their similarities and differences with those reported were discussed. Conclusion: These results would be the important scientific basis for further consideration in the herb authentication of Radix Angelicae Pubescentis.
