Pharmacognosy Identification of Yi Medicinal Material Campanula colorata

[Objectives] To study the original plant,traits and microscopic identification for Yi medicinal material Campanula colorata,and provide experimental data for its identification and medicinal use. [Methods] Plant identification,trait identification,powder identification and paraffin slice identification were adopted in the study. [Results]It was found that the original plant of Campanula colorata was characterized by stiff hairs,slightly thicker root than stem,serrated leaf margin,tubular bell-shaped corolla and blue-purple color; traits were featured by odorlessness,and bitter taste after slight sweetness; the microscopic identification characteristics were that the laticifer was sporadic,containing reddish brown or yellow brown materials,and the oil droplets and nonglandular hairs were common. [Conclusions] The original plant,trait and microscopic identification characteristics were obvious for Yi medicinal material Campanula colorata,which could provide a reference for developing quality standards and identifying the original plant of Campanula colorata,and provide the basis for further research and development.

西南风铃草挥发油的化学成分分析

西南风铃草（Campanula colorata Wall.）,又名岩兰花、土桔梗、土沙参,为桔梗科（Campanulaceae）风铃草属（Campanula Linn.）多年生草本植物,产于中国云南、贵州、四川和西藏,阿富汗和老挝等也有分布[1]。民间常以该种的根入药,主要用于治疗风湿、瘫痪、破伤风和虚痨咳血等[2]。有关风铃草属种类的研究多集中于生物学特性方面[3-4],对该属种类化学成分的研究报道尚不多见。
