Effects of 200 µM MJ, 2 mg/mL YS, and their combinations [MY1 (50 µM MJ and 0.5 mg/mL YS), MY2 (100 µM MJ and 1.0 mg/mL YS), and MY3 (200 µM MJ and 2 mg/mL YS)] on (a) the accumulation of MuA and (b) OXY and RES. The dry root for each treatment was subjected to stilbene extraction using methanol, the content of which was then determined using HPLC and icELISA. The experiment was performed in triplicate (n = 3), and the data are presented as the mean and SD indicated with an error bar. The significance of the mean difference between the precursor treatment and control (CON) was analyzed using a one-way ANOVA followed by the least significant difference at p < 0.01, indicated by *
