[Comparative study on four major active compounds of Sanvitalia procumbens and Chrysanthemum morifolium cv 'Hangju' and 'Gongju'].

The contents of chlorogenic acid, 3,5-O-caffeoylquinic acid, galuteolin and quercitrin in Sanvitalia procumbens and Chrysanthemum morifolium cv. 'Hangju' and 'Gongju' were determined by RP-HPLC. The main active ingredient of S. procumbens was similar to C. morifolium cv. 'Hangju' and 'Gongju'. The content varied significantly. The contents of chlorogenic acid, quercitrin and galuteolin in S. procumbens were 7.46, 46.58, 26.01 mg x g(-1), respectively, and they were the highest among the samples. The content of 3,5-O-caffeoylquinic acid in C. morifolium cv. 'Hangju' was 14.70 mg x g(-1), it was the highest among the samples. The data of the study provide a basis for further research and development of S. procumbens.
