Computational Analysis of Gynura bicolor Bioactive Compounds as Dipeptidyl Peptidase-IV Inhibitor

Figure 2

Chromatograms of G. bicolor leaf samples using HPLC. Five major peaks were observed based on different elution time with peak A identified as 5-O-caffeoylquinic acid, B trans-5-p-coumaroylquinic acid, C cis-5-p-coumaroylquinic acid, D 3,4-dicaffeoylquinic acid, and E 3-caffeoylquinic acid.
