摘要
目的 基于偏振光显微镜结合大图拼接及实时景深影扩展像获取技术,对中国药典2020年版收载的2种贯众类中药绵马贯众、紫萁贯众及3种常见混伪品顶芽狗脊蕨贯众、狗脊蕨贯众、荚果蕨贯众的性状、微性状及组织横切面显微鉴别全息特征进行系统研究,为常见贯众类中药的鉴别提供参考依据.方法 性状鉴别研究采用传统性状及微性状鉴别法;组织横切面显微鉴别研究采用普通光显微镜明场与偏振光显微镜暗场对比观察法,结合实时景深扩展及大型图影像拼接拍摄技术,获取药材组织横切面全息彩色影像图和局部特征高清晰图像,显微图像采用手性对比标注法标注.结果 获取了常见贯众类中药及混伪品的性状、微性状影像数据,首次获取该类药材组织横切面普通光及偏振光显微特征全息彩色影像数据,寻找到不同品种间的药材性状及组织横切面显微鉴别差异,根据主要特征制作鉴别快速检索表和对比表.结论 可综合应用性状、微性状及组织横切面显微鉴别特征快速鉴定常见贯众类中药及混伪品,尤其是叶柄残基横切面的偏振光全息显微特征具有较高的识别度,具有显著的鉴别意义.
Abstract
Objective To study on the traits,micro-traits and microscopic identification characteristics of common cyrtomium Chinese medicines,including Dryopteridis Crassirhizomatis Rhizoma,Osmundae Rhizoma which were recorded in 2020 edition of Chinese Pharmacopoeia and their three chaotic breeds(Woodwardia unigemmata(Makino)Nakai,Woodwardia japonica(L.F.)Smith and Matteuccia struthiopteris(L.)Todaro,providing a reference for the identification and reference of cyrtomium Chinese medicine.Methods Morphological and micro-character identification methods were used in the character identification,and the normal bright field and polarized dark field contrast observation methods were used in the microscopic identification of cross-sections,combined with extended depth of field imaging and large image stitching techniques,to obtain holographic color images and local feature high definition image.The Chiral labeling methods were used to identified the images.Results The image data of the characters,micro-characters and the normal light and polarized light holographic color image data of cross-section of common cyrtomium herbs and its chaotic varieties were obtained at the first time.The main identification feature retrieval tables and correlation tables of medicinal materials,traits,micro traits and microscopic characters were made.Conclusion Common cyrtomium herbs and its three chaotic varieties can be identified by using characters,micro-characters and microscopic identification comprehensively,especially the microscopic character under polarized light of the cross-section,which has obvious identification significance.
