Abstract

OBJECTIVE

To provide anatomical evidences for the morphological and histological identification of 20 medicinal species in Hypericum.

METHOD

Morphological and anatomical study on the organs of 20 medicinal species in Hypericum using tissue clearing, paraffin sectioning and thin sectioning.

RESULT

According to their anatomical characteristics, the secretory structures can be divided into nodules, secretory cavities (canals) and tiny secretory tubes of 20 medicinal species in Hypericum. Hypericin was produced and stored in the nodules, while the volatile oil was produced and stored in the secretory cavities (canals) and tiny secretory tubes. The types differed markedly from each other in location, diameter and distributional density of leaf, and the anatomical structures differed from each other of stem, calyx, petal, anther and fruit among the 20 species in Hypericum.

CONCLUSION

The secretory structures may be as anatomical evidences for the morphological and histological identification of 20 medicinal species in Hypericum.

摘要

目的

为金丝桃属20种药用植物的形态和组织学鉴定提供解剖学依据。

方法

采用组织透明法、石蜡切片法和薄切片法对金丝桃属20种药用植物的器官进行形态和解剖学研究。

结果

根据解剖学特征，金丝桃属20种药用植物的分泌结构可分为分泌细胞团、分泌腔（道）和微小分泌管。金丝桃素在分泌细胞团中产生和储存，而挥发油在分泌腔（道）和微小分泌管中产生和储存。在叶的位置、直径和分布密度方面，这些类型彼此差异显著，在金丝桃属20种植物中，茎、花萼、花瓣、花药和果实的解剖结构也各不相同。
