ABSTRACT

Objective Taking the total amino-acid, total flavones, chlorogenic acid, and volatile oil in Chrysanthemum morifolium as index to investigate the internal quality which relates to collection periods and processing methvods in order to compare the quality of species from oringinal habitats. Methods The contents of colorogenic acid in C. morifolium was analyzed by HPLC; the content of total flavones and amino-acid in C. morifolium were measured by spectrophotometery; and the volatile oil obtained by steam distilation extraction was weighted. Results The every indexes of viviparious chrysanthemum except chlorogenic acid was the best among various flowering periods so the viviparious chrysanthemum can be used as the first-class tea. The common tea produced by half-booming and full-booming flowers with higher yield and appropriate index. The machine processing is fast and suitable for the production to a large-scale. Conclusion The quality of C. morifolium planted in Ruicheng, Shanxi Province is equal to that in Tongxiang, Zhejiang Province, which depends on the collecting periods and processing methods, so does the volatile oil rather than the evironment of the habitat.
