RESUMO
OBJECTIVE: To study the dynamic accumulation of flavonoids in Chrysanthemum morifolium in order to chose the optimal harvest time. METHOD: The flavonoid content was determined in various C. morifolium and in different periods. RESULT AND CONCLUSION: The accumulation of flavonoid in various Chrysanthemum reached a high level when lingulate flowers were in 50% blossom and tube ones in 30% or lingulate flowers were in 70% blossom and tube ones in 50%. Only few of C. morifolium reached a high level of flavonoid, when 1 both ingulate and tube flowers blossomed fully.

OBJECTIVE: To study on dynamic accumulation of various flavone in Chrysanthemum morifolium, in order to appraise the quality of flavone. METHOD: The extract was hydrolyzed and the flavonoid components were determined by RP-HPLC. RESULT AND CONCLUSION: In the samples from Tongxiang, Tezhongboju showed the highest flavonoids content with the total flavone 9.81%, quercetin 4.17 per thousand and apigenin 17.02 per thousand. In the samples from Sheyang, Hongxinju showed the highest content of luteolin with 6.84 per thousand. In the samples from Jiangning, Tezhongboju showed the highest content of total flavone with 7.59%, Yizhongdabaiju showed the highest content of quercetin with 2.78 per thousand, Sheyangxiaobaiju showed the highest content of luteolin with 4.27 per thousand, Sheyanghongxinju showed the highest content of apigenin with 11.20 per thousand. There were differences in the content of flavonoids among the different cultivars, and the same cultivars showed also different when planted in different areas.

OBJECTIVE: To study the quality and the chemical components of Chrysanthemum morifolium from Tongxiang city. METHOD: Chemical constituents of nine cultivars were compared in three types of index: chlorogenic acid, flavonoid and volatile oil. RESULT AND CONCLUSION: The content varied significantly. The content of chlorogenic acid in Jinjuerhao was 6.66%, the highest among the samples. Yizhongdabaiju showed the highest flavonoid and volatile oil with 9.49% and 3.30 mL x kg(-1) respectively.
