Objective The study aimedto investigate the effects and metabolic mechanisms of Gegen Qinlian Decoction （GQD） containing serum on hypoxia?induced glucose metabolism in L02 cells. Methods The effects of five hypoxia durations （6， 12， 18， 24， and 48 hours） on glucose consumption and cell viability of L02 cells were examined under hypoxic conditions to determine the optimal hypoxia time. Normal hepatocytes served as the normal control group. L02 cells with hypoxia?induced reduction in glucose consumption were divided into several groups： hypoxia group， metformin 2 mmol/L group， and 25 g/kg GQD groups treated with 5%， 10%， and 15% GQD containing serum. Glucose consumption was used as an indicator of drug efficacy. High?resolution liquid chromatography tandem quadrupole time?of?flight mass spectrometry （UPLC?Q?TOF?MS） was employed to collect metabolite signals from each group. Data were analyzed by using Progenesis QI software， and potential biomarkers were identified through online databases such as HMDB. Finally， metabolic pathways of potential biomarkers were analyzed via the Metabo Analyst 5.0 website. Results An 18 hour hypoxia period was identified as the optimal duration for the replication of the hypoxia?induced L02 cell model. GQD containing serums at 5% and 10% significantly increased glucose consumption in hypoxia?induced L02 cells after 18 hours. 14 biomarkers of hypoxia?induced L02 cells were identified， with the levels of 13 biomarkers significantly increased and 1 biomarker significantly decreased. GQD containing serum notably regulated the levels of 3 biomarkers. Conclusion GQD containing serum might improve hypoxia?induced abnormal glucose metabolism in L02 cells and enhance glucose consumption by modulating glycerophospholipid metabolism， glycosylphosphatidylinositol biosynthesis， and sphingolipid metabolism.
