【摘要】 目的:对蓝玉簪龙胆的形态组织学进行考察,确定其鉴别特征。方法:采用生药学常规方法,对蓝玉簪龙胆进行原植物、药材性状观察,并对其鉴别特征进行描述;采用表皮制片法及水合氯醛透化法观察蓝玉簪龙胆叶和粉末的显微特征,药材粉末图用显微描绘镜绘制,并对部分显微特征进行了显微摄影;将蓝玉簪龙胆的花粉粒、种子自然风干,粘台、镀金后通过电子扫描电镜观察花粉粒及种皮微形态特征。结果:确定了蓝玉簪龙胆在形态组织学方面的鉴别特征。结论:为蓝玉簪龙胆品种的准确鉴定及应用提供科学依据。更多还原

【Abstract】 Objective: To study the morphology and histology of Tibetan medicine Gentiana veitchiorum and determine the main identification characteristics. Method: Original plants and herbal properties were identified with pharmacognostical method. Its identification characteristics were described in this paper. The slide made with chloral hydrate and epidermis flaking methods was adopted to observe the microscopic identification of the powder and leaves. By using microscope,the graphs of herbal powders were printed,and parts of the microscopic characters were photographed. The pollen grains and seeds were naturally dried,stuck on test-bed and gold plated,then their micromorphological features were observed by scanning electron microscopy( SEM). Result: The identification characteristics of G. veitchiorum were determined in terms of morphology and histology. Conclusion:The study offers a scientific basis for accurate identification and application of Tibetan medicine G. veitchiorum.更多还原
