New triterpenoid saponins from Glochidion eriocarpum and their cytotoxic activity.
Combined chromatographic methods led to the isolation of two new triterpenoid saponins, glochieriosides A and B (1, 2), from the aerial parts of Glochidion eriocarpum, along with three known triterpenes, glochidone (3), lup-20(29)-en-3beta,23-diol (4), and lup-20(29)-en-1beta,3beta-diol (5). The structures of the new saponins were determined to be 22beta-benzoyloxy-3beta,16beta,28-trihydroxyole...
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 کاملTriterpenoid saponins from the roots of Clematis argentilucida and their cytotoxic activity.
The reinvestigation of the n-BuOH extract of the roots of Clematis argentilucida led to the isolation of four new oleanane-type triterpenoid saponins, 1-4, four known saponins, 5-8, first isolated from the species, together with ten saponins, 9-18, reported in the preceding papers. The structures of saponins 1-8 were elucidated by extensive spectroscopic analysis and chemical evidences. The cyt...
متن کاملTriterpenoid saponins from the seeds of Celosia argentea and their anti-inflammatory and antitumor activities.
Three new triterpenoid saponins, named celosin E (1), celosin F (2) and celosin G (3), together with a known compound cristatain (4), were isolated from the seeds of Celosia argentea L. (Amaranthaceae). All the isolated compounds were obtained for the first time from this plant. The structures of new compounds were characterized on the basis of extensive NMR experiments and mass spectrometry da...
متن کاملNew triterpenoid saponins from Stelmatocrypton khasianum.
Four new triterpenoid saponins, designated as stelmatotriterpenosides E-H (1-4), together with three known compounds, asterbatanoside B (5), 2alpha,3beta,19alpha,23-tetrahydroxy-olean-12-en-28-oic acid-3-O-beta-D-glucopyranosyl-28-O-beta-D-glucopyranosyl ester (6) and 2alpha,3beta,19alpha,23-tetrahydroxy-urs-12-en-28-oic acid-3-O-beta-D-glucopyranosyl-28-O-beta-D-glucopyranosyl ester (7), were ...
