Triterpenoid Saponins from Stem Bark of Pentaclethra macroloba
Duas novas e duas conhecidas saponinas triterpênicas foram isoladas da casca do caule de Pentaclethra macroloba. As estruturas foram determinadas usando uma combinação de técnicas de RMN homo(1D: RMNH, RMNC-{H}, RMNC-DEPT135; 2D: H-H-COSY, H-HTOCSY, H-H-NOESY) and heteronuclear 2D (HMQC and HMBC), espectros de massas obtidos com ionização por pulverização eletrônica (ESIMS) e métodos químicos. ...
متن کاملSix new triterpenoid saponins from the root and stem bark of Cephalanthus occidentalis.
From the root and stem bark of Cephalanthus occidentalis L., a common American wetland species, six new triterpenoid saponins (1 - 6), together with 29 known compounds were isolated and identified. On the basis of spectroscopic analysis and chemical degradation, the structures of new compounds were elucidated as 3-O-beta-glucopyranosylcincholic acid (1), cincholic acid 28-O-beta-glucopyranosyl ...
متن کاملAntiproliferative triterpenoid saponins from the stem of Psychotria sp.
Six new triterpenoid saponins, psychotrianosides A-F (1-6), and two known triterpenoid saponins, psychotrianoside G (7) and ardisianoside D (8), were isolated from Psychotria sp. Their structures were determined mainly by spectroscopic methods. The cytotoxic activities of 1-8 against five human cancer cell lines (MDA-MB-231, MCF-7, MCF-7/ADM, HepG2, and HepG2/ADM) are reported for the first tim...

متن کاملTriterpenoid saponins from Stauntonia chinensis.
A new triterpenoid saponin, named stauntoside A (1) along with four known saponins (2,3,4,5) was isolated from Stauntonia chinensis DC., (Lardizabalaceae). Their structures were elucidated by spectroscopic analysis and chemical methods as 3-O-alpha-L-arabinopyranosyl-30-norhederagenin -28-O-beta-D-glucopyranosyl-(1 --> 6)-beta-D-glucopyranosyl ester (1), 3-O-alpha-L-arabinopyranosyl-30- norhede...
