| Description: |
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.

| Phytomedicine, 2014, 21(8-9):1062-1069. | | Antinociceptive activity of the HPLC- and MS-standardized hydroethanolic extract of Pterodon emarginatus Vogel leaves.[Reference: WebLink] | Several studies have demonstrated the analgesic and anti-inflammatory effects of fruit and seed extracts from Pterodon emarginatus Vogel (Fabaceae).
METHODS AND RESULTS:
The objective of this study was to evaluate the antinociceptive activity of the hydroethanolic extract of P. emarginatus leaves in mice and characterize its chemical composition using HPLC coupled to UV–vis diode array detection and mass spectrometry with electrospray ionization. Our results showed that the doses of 500 and 1000 mg/kg produced an antinociceptive effect, as observed in the hot plate test and writhing induced by acetic acid. The chromatographic profile and spectral mass data suggest the presence of di-C-glycosylflavones (e.g., vicenin-2 and schaftoside), C,O-glycosylflavones (e.g., chrysoeriol-8-C-glucosyl-2″-O-glucuronide-6-C-arabinoside) and luteolin-7-O-rutinoside as the main constituents. Lower levels of oleanane-type saponins, such as soyasaponin Bb and soyasaponin Be, and the saponin derivatives hederagenin and aglycone B, which are typical of Fabaceae family, were also found.
CONCLUSIONS:
From this study, it is suggested that the analgesic effect observed is not due to the terpenoids previously reported from fruit and seed extracts, but could be attributed to flavones and the hederagenin derivatives that were identified as main constituents of the hydroethanolic extract from the leaves. |
