紫斑风铃草的鉴定

Identification for Spotted Bellflower

目的:对紫斑风铃草进行鉴定和质量评价。方法:对紫斑风铃草进行包括原植物、药材性状、显微鉴定及质量检查(总灰分、酸不溶性灰分、水分测定)等的鉴定。结果:紫斑风铃草为桔梗科风铃草属植物,其组织及粉末中含有乳汁管、菊糖等桔梗科共性特征,还有方晶、气孔、导管、花粉粒、腺毛、非腺毛等一般组织。测得总灰分9.870%,酸不溶性灰分3.141%,水分含量7.981%。纸色谱中得到深蓝褐色斑点的Rf值为0.5。结论:初步建立了紫斑风铃草的鉴别方法,为进一步建立该药材的质量标准及开发利用奠定了基础。

Objective： To provide identification and quality evaluation for spotted bellflower （campanula punctata）. Method： Original plant, property, microscope and quality （total ash, acid-insoluble ash, water content） of spotted bellflower were identified. Result： Spotted bellflower was of campanulaceae plants and contained the common features of campanulaceae including： laticiferous tube, synanthrin and others in tissue and powder, also normal tissues： prismatic crystal, stoma, vessels, pollen grains, glandular hairs, non-glandular hairs and others. The results showed that total ash accounted for 9.870%, acid-insoluble ash 3.141% and water content 7.981%. Rf value of deep blue brown spot was 0.5 obtained in paper chromatography. Conclusion：Establishing identification method of spotted bellflower initially could lay foundation for quality standard, development and utilization of the drug.
