摘要
目的为玄参叶的开发利用和质量控制提供科学依据。方法按生药学常规方法对玄参叶进行形态解剖学研究,其中组织切片采用徒手切片和石蜡切片相结合的方法,叶表面制片采用撕取表皮的方法,叶表面扫描电镜观察采用脱水、干燥、喷金后常规扫描的方法,组织、叶表面、粉末图均采用显微拍摄。结果找出了玄参叶的性状和显微鉴别特征。结论此研究可作为鉴定玄参叶的依据。
Objective To provide a scientific basis for the development and quality control of the leaves of Scrophularia ningpoensis.Methods The routine methods in pharmacognosy were used for the morphological and anatomical analyses of the leaves of Scrophularia ningpoensis.Tissue section was made by the combination of bare-handed section and paraffin section.Leaf surface slicing were used the method of tearing the epidermis.Scanning electron microscopy of leaf surface was performed by conventional scanning after dehydration,drying and spraying of gold.Microscopic photography was used for tissue,leaf surface and powder image.Results The morphological characteristics and microscopic characteristics for identification of the leaves of Scrophularia ningpoensis were summarized.Conclusion This study provides a basis for the identification of the leaves of Scrophularia ningpoensis.
