Steroidal Saponins from the Roots and Rhizomes of Tupistra chinensis.
Two new furostanol saponins 1-2 and a new spirostanol saponin 3 were isolated together with two known furostanol saponins 4-5 from the roots and rhizomes of Tupistra chinensis. Their structures were characterized as 1β,2β,3β,4β,5β,26-hexahydroxyfurost-20(22), 25(27)-dien-5,26-O-β-d-glucopyranoside (1), 1β,2β,3β,4β,5β,6β,7α,23ξ,26-nona-hydroxyfurost- 20(22),25(27)-dien-26-O-β-d-glucopyranoside (...
متن کاملFour new furostanol saponins from the rhizomes and roots of Smilax scobinicaulis and their cytotoxicity.
Four new furostanol saponins 1-4, along with two known furostanol saponins 5 and 6 and one known spirostanol saponin 7 were isolated from the rhizomes and roots of Smilax scobinicaulis. The structures of the new saponins were elucidated as 26-O-β-D-glucopyranoside-3β,26-dihydroxy-(25R)-5α-furostan-22-methoxyl-6-one-3-O-α-L-arabinopyranosyl-(1→6)-β-D-glucopyranoside (1), 26-O-β-D-glucopyranoside...
متن کاملCharacterization of phenolic compounds and antioxidant properties of Glycyrrhiza glabra L. rhizomes and roots
The present work aims to characterize and quantify the phenolic composition and to evaluate the antioxidant activity of Glycyrrhiza glabra L. (commonly known as licorice) rhizomes and roots. The antioxidant potential of its methanol/water extract could be related to flavones (mainly apigenin derivatives), flavanones (mainly liquiritin derivatives), a methylated isoflavone and a chalcone, identi...
متن کاملCompounds from the roots and rhizomes of Valeriana amurensis protect against neurotoxicity in PC12 cells.
Three new germacrane-type sesquiterpenoids, heishuixiecaoline A-C (compounds 1-3), were isolated along with ten known compounds 4-13 from fraction of Valeriana amurensis roots and rhizomes effective against Alzheimer's disease (AD). The structures of 1-3 were elucidated on the basis of their spectroscopic data. We also investigated the protective effect of compounds 1-13 on the neurotoxicity of...
متن کاملEvaluation of CNS activities of ethanol extract of roots and rhizomes of Cyperus rotundus in mice.
The ethanol extract of Cyperus rotundus (EECR) was tested for possible pharmacological effects on experimental animals. EECR significantly potentiated the sleeping time of mice induced by standard hypnotics, viz. pentobarbitone sodium, diazepam, and meprobamate in a dose dependent manner. EECR showed significant analgesic properties as evidenced by the significant reduction in the number of wri...
