51 Additionally, protodioscin undergoes deglycosylation to form pseudoprotodioscin, which is subsequently deglycosylated to form secondary saponins, leading to a decreasing trend in the former and a rise-then-fall trend in the latter. 52 The dynamic process of glycosidic bond cleavage is exemplified by the thermal degradation of dioscin ( Fig. 2 ), which illustrates the generation of its aglycone and monosaccharides.
