Abstract

Abstract:

Anoectochilus chapaensis Gagnep. (Orchidaceae) was named as the “king of medicine” because of its excellent efficacy for the treatment of diabetes. However, the bioactive constituents are unknown. An ethanol extract from A. chapaensis showed significant stimulating effect on glucose consumption in HepG2 cells. The chemical composition was investigated by UPLC-MS/MS in negative electrospray ionization (ESI) mode, and 63 compounds including flavonoids, triterpenoids, and aliphatic acids were tentatively identified by accurate mass and characteristic fragments. Moreover, the method of hypoglycemic screening with insulinresistant HepG2 cells and UPLC-MS/MS might be potentially useful in rapid and efficient characterization and primary prediction of natural products prior to traditional isolation.

Key words: UPLC-MS/MS, Hypoglycemic, HepG2 cells, Anoectochilus chapaensis
