cqvip:[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.
