Fig. 6From: Comparing the antidiabetic effects and chemical profiles of raw and fermented Chinese Ge-Gen-Qin-Lian decoction by integrating untargeted metabolomics and targeted analysisProposed fermentation-induced chemical transformation mechanisms. a1 Flavone O-glucuronides; b1 alkaloids; a2 proposed biotransformed pathways of flavone O-glucuronides; b2 proposed biotransformed pathways of alkaloids. Solid arrows: prone to happen; dotted arrows: speculated/less likely to happen.
