Abstract:
The present research aimed to establish an associated two-dimensional fingerprint of Huanglian between characteristic chemical composition and antioxidant activity, which was applied to on-line screen the active constituents. In this study, the HPLC-ABTS-DAD-Q-TOF/MS method, which can simultaneously identify individual components and rapidly screen for antioxidant compounds, was used to screen and identify antioxidant components in Huanglian. Fourteen compositions were discovered, and eight of them displayed antioxidant activity. The antioxidant activity of different ingredients was evaluated by antioxidant efficiency. The data showed that 2, 3, 4-trihydroxy phenylpropionic acid, chlorogenic acid, ferulic acid, cularine, 3-O-feruloylquinic acid and feruloyltyramine showed stronger antioxidant activity than that of alkaloids. These experimental data can provide data support for the basic research of the antioxidant ingredients of Huanglian.
