Morphological Characteristics and Quality Comparison of Clerodendranthus spicatus with Purple Corollas and White Corollas
摘要
Abstract
Objective:To compare the differences of morphological characteristics and quality between Clerodendranthus spicatus with purple corollas and white corollas,so as to provide a theoretical basis for the the quality standard establishment and comprehensive utilization of resources.Methods:The morphological characteristics of the two species were observed and compared by means of original plant identification,character identification and microscopic identification.Colorimetric method was used to determine the contents of to-tal phenolic acid and total flavonoids.The contents of caffeic acid,rosmarinic acid and xeranthine were determined by HPLC.Results:Compared with Clerodendranthus spicatus with white corollas,Clerodendranthus spicatus with purple corollas had shorter plants and smal-ler leaves.The length and width of calyx were obviously larger than that of Clerodendranthus spicatus with white corollas.There were also differences in the microscopic features of non-glandular hairs,pollen grains and leaf epidermal stomata.The contents of total phenolic acid,total flavone,caffeic acid,rosmarinic acid and xeranthine in Clerodendranthus spicatus with purple corollas were higher than those in Clerodendranthus spicatus with white corollas.Conclusion:It is suggested that Clerodendranthus spicatus with purple corollas and white corollas should be listed separately in the formulation of the standard of medicinal materials in order to ensure the scientific and rational development and utilization of its medicinal resources.关键词
