目的:比较杭白菊6个品种的主要化学成分分布规律,为探索菊花综合开发利用提供依据。方法:采用HPLC法测定6个不同品种杭白菊根、茎、叶、花序中绿原酸、木犀草苷、3,5-O-二咖啡酰基奎宁酸的含量;用紫外分光光度法测定总黄酮的含量。结果:杭白菊不同部位间绿原酸、3,5-O-二咖啡酰基奎宁酸、总黄酮含量均有显著差异,木犀草苷含量花序中最高,根、茎、叶中木犀草苷含量差异不明显;6个品种杭白菊间绿原酸、3,5-O-二咖啡酰基奎宁酸、总黄酮含量均有明显的差异,木犀草苷含量差异不明显。结论:6个品种杭白菊根、茎、叶中均有较高含量的绿原酸、3,5-O-二咖啡酰基奎宁酸、总黄酮,只有木犀草苷主要分布于花序中,可进一步开发利用菊花的茎、叶、根。
Objective: To compare the distribution of the main chemical components of 6 varieties of Chrysanthemum, providing a basis for exploring the comprehensive development and utilization of chrysanthemum. Methods: The contents of chlorogenic acid, luteolin and 3,5-O-dis Caffeoylquinic acid in roots, stems, leaves, and inflorescences of 6 different varieties were determined by HPLC. Flavonoids content. Results: The contents of chlorogenic acid, 3,5-O-dis Caffeoylquinic acid and total flavonoids in different parts of Chrysanthemum morifolium were significantly different. The contents of luteolin in the inflorescences were the highest. The contents of luteolin in roots, stems and leaves The difference was not obvious. The content of chlorogenic acid, 3,5-O-discaffeoylquinic acid and total flavonoids in 6 varieties of Chrysanthemum morifolium had obvious difference, and the content of luteolin was not obvious. CONCLUSION: Chlorogenic acid, 3,5-O-discaffeoylquinic acid and total flavonoids are present in roots, stems and leaves of 6 varieties of Chrysanthemum, and only luteolin is mainly distributed in the inflorescences. Further development and utilization of chrysanthemum stems, leaves, roots.
