葫芦科5种种子类药材的生药学研究及数字化

Studies on the pharmacognosic and digital characters of five Cucurbitaceae medicinal seeds

目的:探讨葫芦科种子类药材生药学鉴定方法,将鉴定特征数字化。方法:运用体式显微镜、光学显微镜从外观性状(整体观、顶面观、侧面观、表面特征)、内部结构(横剖面、纵剖面)及显微特征(横切面)对葫芦科5种药用植物种子进行深入的性状和显微鉴别研究,初步探讨葫芦科种子类药材的鉴别特征,并用数字化的形式对鉴别点进行表征。结果:葫芦科5种药用植物种子在性状、显微横切面上有一定共性特征,但可根据种子表面、剖面观等性状鉴别特征及种皮组织横切面等显微鉴别特征进行鉴别。结论:本研究为葫芦科5种种子类药材的品种鉴定奠定基础,为葫芦科药用植物种子的监督检验和标准修订提供参考,也为种子类药材的数字化表征提供参考。

Objective:To explore the method of pharmacognosic identification of Cucurbitaceae medicinal seeds,and to digitize the identification characteristics.Methods:The seeds of five Cucurbitaceae medicinal plants were studied by means of type microscope and light microscope,including the appearance(integral view,top view,lateral view and surface feature),internal morphology(cross profile and longitudinal profile)and the characters of micromorphology(transverse section).The characteristics of the seeds of Cucurbitaceae were summarized,and the identification points were characterized by digital method.Results:The seeds of five Cucurbitaceae medicinal plants had some common characteristics in character and microscopic cross section,but the five could be identified according to the seed surface and cross section characteristics of seed coat tissue.Conclusion:This study lays a foundation for the variety identification and provides reference for the standard formulation and quality control of five Cucurbitaceae medicinal seeds.It also provides ideas for digital characterization of seed medicinal materials.
