3'-Methoxydaidzein has antioxidant activity, it and geraldol have antiplatelet aggregation activity and appear to be specific against collagen induce platelet aggregation with a IC50 values of12.3 and 61.5 μM, respectively.

The eight components were identified by chemical and spectroscopic methods as 2?2,3?2,7-trihydroxy-4?2-methoxyisoflavanone (2), 3'-Methoxydaidzein (3), 4?2,5,7-trihydroxy-3-methoxyflavone (4), vestitol (5), medicarpin (6), hexanoic acid, 2-propenylester (7), hexadecanoic acid, ethyl ester (8) and 3,8,-nonadien-2-one (9). Their antioxidant activities were investigated and compared with butylated hydroxyluene (BHT) and α±-tocopherol. The results showed that components 1, 3, 5 and 6 had antioxidant activity and components 2 and 4 had strong antioxidant activity at 0.02 and 0.04% levels. When the individual components (0.02%) were mixed with 0.02% BHT, or 0.02% α±-tocopherol, their protection factor was increased, but there was no synergistic effect. When the individual component had 4 ppm added Fe3+, components 1, 2, 3 and 4 had antioxidant activity. Their antioxidant activities were tested by an oxidative stability instrument (OSI) at 100°C.
