Stability of dioscin and diosgenin in SGF (pH 1.2).

Incubation time (min)	Dioscin (glycoside)			Diosgenin (aglycone)
	Amount of dioscin in SGF (μg/mL)	Formation of diosgenin with time (%)	% RD of dioscin depletion	Amount of diosgenin in SGF (μg/mL)	% RD of diosgenin depletion
0	45.0 ± 4.0	–	–	52.4 ± 0.9	–
30	37.5 ± 1.2	6.3	16.7	50.5 ± 0.9	3.62
60	34.4 ± 1.1	19.8	23.6	48.0 ± 1.9	8.31
120	32.3 ± 1.0	24.2	28.3	47.9 ± 1.1	8.59

Data are expressed as mean ± SD of triplicate samples from one experiment. RD = Relative difference.
