Cytotoxic oleanane-type saponins from Albizia inundata.
Bioassay-guided fractionation of a CH(2)Cl(2)-MeOH extract of the aerial parts of Albizia inundata resulted in the isolation of two new natural oleanane-type triterpene saponins {3-O-[α-L-arabinopyranosyl(1→6)]-2-acetamido-2-deoxy-β-D-glucopyranosyl oleanolic acid (1) and 3-O-[α-L-arabinopyranosyl(1→2)-α-L-arabinopyranosyl(1→6)]-2-acetamido-2-deoxy-β-D-glucopyranosyl acacic acid lactone (2)} al...

Five new oleanane-type triterpene saponins including steganogenin 3-O-β-D-glucopyranoside (1), steganogenin 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranoside (2), steganogenin 3-O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranoside (3), chichipegenin 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranoside (4) and chichipegenin 3-O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranoside (5), along with four known olean...
متن کاملAntimicrobial steroidal saponin and oleanane-type triterpenoid saponins from Paullinia pinnata
BACKGROUND Paullinia pinnata L. (Sapindaceae) is an African woody vine, which is widely used in traditional medicine for the treatment of human malaria, erectile dysfunction and bacterial infections. A phytochemical investigation of its methanol leaf and stem extracts led to the isolation of seven compounds which were evaluated for their antimicrobial properties. METHODS The extracts were fra...
متن کاملAntibacterial and antioxidant properties of crude extract, fractions and compounds from the stem bark of Polyscias fulva Hiern (Araliaceae)
BACKGROUND In our previous work, the dichloromethane-methanol (1:1 v/v) extract, fractions and isolated compounds from Polyscias fulva stem bark showed interesting antifungal activity. As a continuity of that work, this study aimed to bring out complementary informations about the antimicrobial properties of P. fulva stem bark that may be useful in the standardization of phytomedicine from this...
متن کاملOleanane-Type Saponins from the Roots of Ligulariopsis shichuana and Their α-Glucosidase Inhibitory Activities.
Five new oleanane-type saponins, named ligushicosides A-E, and three known oleanane-type saponins were isolated from the roots of Ligulariopsis shichuana. Their structures were established by a combination of spectroscopic techniques, including 1D and 2D NMR and high resolution electrospray ionization mass spectroscopy (HR-ESI-MS). Furthermore, all isolates were evaluated for their yeast α-gluc...
