目的 对蒙药地梢瓜(蒙语名“特莫-呼呼”)(以下简称地梢瓜)进行性状和显微鉴定研究,为地梢瓜与其易混品及代用品的深入研究奠定实验基础。方法 运用数码相机、体视显微镜及其数码成像技术,系统对地梢瓜外部性状进行观察和表征;运用光学显微镜及其数码成像技术对其内部构造(横切面、粉末)进行观察和表征。结果 通过研究进一步明确了地梢瓜的性状及显微鉴定特征。性状鉴定主要从形状、大小、颜色、表面构造等方面进行鉴定,并建议地梢瓜表面特征描述修订为“呈扁平的卵圆形,边缘薄,渐狭呈翼状。一面微凹,中间有一深色种脊,约占全长的2/3”;显微鉴定主要从种皮表皮细胞、色素层细胞等方面进行鉴定,并建议横切特征描述修订为“外壁大多向外突起呈乳突状或延伸似非腺毛,棕黄色”“内种皮细胞为色素层,内含草酸钙结晶”及“子叶组织散有原生维管束”。结论 通过生药学研究与数字化表征可以为地梢瓜标准中性状和显微鉴别相关术语及其描述的修订提供参考,也为民族药品种的数字化平台建设提供示范基础。
Abstract
OBJECTIVE To study the macroscopic and microscopic identification of mongolian medicine Semen Cynanchi (“Temo-huhu”), and to lay an experimental foundation for the identification of Semen Cynanchi and its adulterants. METHODS Digetal camera, stereomicroscope combined with digital imaging technology were used to observe and characterize the surface characters of Semen Cynanchi systematically. Microscope with digital imaging technology was used to observe and characterize the endocarp features(transverse section and powder). And input the obtained data into the digital specimen platform. RESULTS The macroscopic and microscopic characteristics of Semen Cynanchi were identified through this study. The shape, size, color and especiall surface were the main macroscopic characters for the identification. The description of the surface was revised as “it is flat oval, with thin edge and gradually narrow wing shape. One side is slightly concave, a dark ridge in the middle, accounting for about 2/3 of the total length”.The epidermal cells and pigment layer cells were the main microscopic identification characters. The description of the surface was revised as “most of the outer walls protrude outward like mastoid or extended like nonglandular hair, claybank”, “The endotesta cells are pigment layer containing calcium oxalate crystals” and remove the description of mesophyll. The research results differ from those described in current legal standard. CONCLUSION Through pharmacognosy study and digitization, it can provide reference for the revision of relevant terms and descriptions of macroscopic and microscopic identification of Semen Cynanchi, and also lay a foundation for the construction of digital platform for ethnic medicine.
