Comparative study on botanical characters and main chemical components between HebeiXiangju and Chrysanthemum morifolium Ramat

The botanical characters and main chemical components were studied by comparing HebeiXiangju with other Chrysanthemum morifolium.Results showed that there were significant differences in botanical characters in the inflorescence bud scale,the diameter of head inflorescence and the layers of ray florets between HebeiXiangju and other cultivars of C.morifolium.Compared with other C.morifolium,the amount of volatile oil was 2.61-11.36 times higher;that of total flavonoid,1.36-3.17 times;that of chorogenic acid,1.79-2.53 times higher respectively,suggesting that HebeiXiangju has higher medicinal values.
