摘要
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.
