Soy saponins (ssp) have shown to possess the health‐promoting properties. Finding soy varieties with high ssp content and increasing ssp content in a variety will increase their beneficial effects. The objective of this study is to find the effect of elicitors sprayed on Ozark, R95‐1705, and UA4805 on ssp content. Elicitors, salicylic acid (SA), ethyl acetate (EA), and methyl salicylate (MS), were sprayed at 10 −3 and 10 −1 M concentrations. Seeds were ground (60 mesh), defatted, and ssp was extracted. Variety had significant effect on ssp I, II, III, αg, βg, and βa of soybeans (P<0.0001). Ozark had higher total ssp content than UA4805 and R95‐1705 (4.2, 2.8, and 2.8 μmol/g soybean, respectively). Elicitor and variety had significant interaction on ssp II content of soybeans (P=0.0190). Elicitor had significant effect on total and ssp III contents (P=0.0058 and 0.035, respectively) of soybeans. Ozark had higher βg and βa contents than R95‐1705, followed by UA4805 (βg 2.70, 1.90, and 0.90; βa 0.96, 0.46, and 0.17 μmol/g soybean, respectively). The findings of this study will provide valuable data on the application of natural elicitors to increase ssp content. Higher content of ssp in soybean will improve health beneficial effects.
