山西芮城引种白菊花中主要有效成分的比较研究

目的以白菊花内总氨基酸、总黄酮、绿原酸和挥发油等有效成分为指标,探索山西芮城白菊花质量与采收期、加工方法的关系并与原产地白菊花比较质量。方法运用水蒸气蒸馏法测定挥发油的量,采用分光光度法测定总黄酮和总氨基酸的量以及HPLC法测定绿原酸的量。结果胎菊除绿原酸外各指标显著高于各花期,可作为高等茶饮,普通茶饮品以半开菊和盛开菊适合,产量较高,指标适合。加工方法以机械加工更快、更适宜大生产。结论白菊花质量与采收期和加工方法有很大的关系。山西引种白菊花主要有效成分的量与原产地相当;挥发油量受采收期和加工方法的影响大于产地环境影响。

Comparative study on main components of Chrysanthemum morifolium introduced in Ruicheng in Shanxi Province

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.
