As an attempt to search for bioactive natural products exerting antiinflammatory activity, we have isolated two saponins were isolated from the aerial portion of Pleurospermum kamtschaticum (Umbelliferae) by nitrite assay activity-directed chromatographic fractionation. They were identified as
Buddlejasaponin IV (BS-IV), a major component of Pleurospermum kamtschaticum, exerts antiinflammatory and cytotoxic effects against cancer cells. The study investigated whether BS-IV could prevent oral carcinogenesis by inhibiting the growth of immortalized human oral keratinocytes (IHOKs). BS-IV
BACKGROUND
Buddlejasaponin IV (BS-IV), a triterpene saponin isolated from Pleurospermum kamtschaticum HOFFMANN (Umbelliferae), is known to have potent anti-inflammatory activity and cytotoxicity against diverse cancer cell lines. In the present study, we attempted to verify whether BS-IV could
Three saponins, craniosaponin A (1) and buddlejasaponins Ia (2) and I (3) were isolated from the n-butanol soluble fraction of Craniotome furcata for the first time. Among them, craniosaponin A (1) was identified to be a new compound. The structure of craniosaponin A was assigned mainly by spectral
Three triterpene saponins isolated from the roots of Physospermum verticillatum and identified as saikosaponin a (1), buddlejasaponin IV (2), and songarosaponin D (3) were investigated in vitro for their cytotoxic activity against a panel of seven different cancer cell lines including ACHN, C32,
