Pd-C-II has anti-inflammation activity, it can inhibit TNF-α production and iNOS protein expression and inhibit COX-2 protein expression in LPS-stimulated RAW 264.7 cells. Pd-C-II inhibits anaphylactic mediator release from purified mast cells induced by concanavalin A with phosphatidylserine, the IC50 value of 79 microM.

1. Platycoside E can significantly promote the production of the sera ovalbumin (OVA)-specific IgG2a and IgG2b antibody in the OVA-immunized mice .

Pseudoaspidin is a product from Agrimonia pilosa Ledob.

1. Saponin V (300,150,75 mg·kg-1) can significantly decrease the times of cough, saponin V 300 mg/kg can remarkably increase cough latent period, saponin V 5 g/L remarkably antagonized contraction of isolated ileum, saponin V 2.5 and 1.25 g/L antagonized trachea spasm in guinea pig induced by histamine; saponin V exhibits significant antitussive, expectorant and antispasmodic effects.
2. Chikusetsu saponin V can attenuate H2O2-induced oxidative stress in human neuroblastoma SH-SY5Y cells through Sirt1/PGC-1α/Mn-SOD signaling pathways, suggests that chikusetsu saponin V exhibits neuroprotective effects.

1. Soyasaponins has chemoprevention activities, it prevent H₂O₂-induced inhibition of gap junctional intercellular communication by scavenging reactive oxygen species in rat liver cells.
2. Soyasaponins can significantly decrease blood glucose, improve atherosclerotic index, and inhibit lipid peroxidation and platelet aggregation in diabetic rats, which may be useful in prevention and control of diabetes mellitus and diabetes-associated atherosclerosis.
3. Soyasaponins abundant in soybean have anti-inflammatory activities, low-dose SSs alleviated contact hypersensitivity (CHS) symptoms by attenuating inflammation and improving the intestinal microbiota composition, suggesting that dietary SSs may have beneficial effects on allergic contact dermatitis (ACD).
4. Dietary soyasaponin has inhibitory effects on 2,4-dinitrofluorobenzene-induced contact hypersensitivity in mice.
