HPLC analysis chromatogram (a) and the structures (b) of constituent chemicals for Aster glehni ethyl acetate extract. The main phytochemicals identified from Aster glehni are caffeoylquinic acids of seven kinds: (1) 5-CQA: 5-caffeoylquinic acid, (2) 3,4-DCQA: 3,4-dicaffeoylquinic acid, (3) 3,5-epi-DCQA: 3,5-epi-dicaffeoylquinic acid, (4) 3,5-DCQA: 3,5-dicaffeoylquinic acid, (5) 4,5-DCQA: 4,5-dicaffeoylquinic acid, (6) 3,5-DCQA-Me: methyl 3,4-dicaffeoylquinic acid, and (7) 4,5-DCQA-Me: methyl 4,5-dicaffeoylquinic acid.
