Advances in Triterpenoid Saponins Research 2007-2012

چکیده
Triterpenoid saponins isolated and identified from natural resources during the period April, 2007-December, 2012 are reviewed. Current techniques used in their isolation and structure determination are discussed. New triterpenoid saponins isolated along with their occurrence, selected physical data, spectroscopic methods used for their identification and the 13C NMR data of the novel aglycones of the parent saponins are compiled. The biological properties of those molecules are also included. Green corrosion inhibition effects of saponins and biosynthesis of triterpenoid saponins and production of triterpenoid saponins by tissue culture of those molecules are also discussed.

متن کاملCytotoxic triterpenoid saponins from the roots of Platycodon grandiflorum.
Bioguided fractionation of the ethanol extracts obtained from Platycodon grandiflorum roots led to isolation of two new triterpenoid saponins, characterized as 3-O-beta-D-glucopyranosyl-2beta,12alpha,16alpha,23,24-pentahydroxyoleanane-28(13)-lactone (1) and 3-O-beta-D-glucopyranosyl-(1-->3)-beta-D-glucopyranosyl-2beta,12alpha,16alpha,23alpha-tetrahydroxyoleanane-28(13)-lactone (2) by 1D- and 2D...

متن کاملAnalysis of gypsogenin saponins in homeopathic tinctures.
A relatively simple and short procedure for the quantitative determination of gypsogenin saponins was performed to evaluate homeopathic tinctures in which those compounds can be regarded as one of the active constituents. This method comprises partial hydrolysis of saponins, subsequent extraction of liberated prosaponin (gypsogenin 3-O-glucuronide) and its analysis by high performance liquid ch...
متن کاملDirect detection of triterpenoid saponins in medicinal plants.
Direct detection of saponins in medicinal plants using Fourier Transform Infrared (FTIR) spectroscopy is reported in this paper. Crude dry plant powders were mixed with potassium bromide (KBr) powder and compressed to a thin pellet for infrared examination. FTIR spectra of the test samples showed -OH, -C=O, C-H, and C=C absorptions characteristic of oleanane triterpenoid saponins. The C-O-C abs...
