Multi-model Evaluation of Anti-glycation Effects of Sophora japonica Flowers Aqueous Extract and Its Active Components Analysis

Objective: To investigate and analyze anti-glycation effects of the aqueous extract of Sophora japonica flower (SJF) by using different models, as well as its active constitutes identification. Methods: BSA/reducing sugar reaction system, glycosylated fibroblast induced by methylglyoxal and AGEs-increased zebrafish model triggered by glucose solution were simultaneously established to comprehensively evaluate the anti-glycation effects of SJF aqueous extract from biochemical, cellular and zebrafish aspects, respectively. Identification of major components was performed by ultra-high performance liquid chromatography-high resolution mass spectrometry technique (UPLC-Triple TOF/MS). Biochemical system was subsequently adopted to further analyze anti-glycation effects of these primary components. Results: In the BSA/reducing sugar system, IC50 of AGEs inhibition of SJF aqueous extract was 53.93 μg/mL. 10 and 40 μg/mL of SJF aqueous extracts dramatically inhibited CML expressions in fibroblast model (P
