Triterpene glycosides from astragalus angustifolius

Six new cycloartane-type (1-6) and four new oleanane-type (7-10) triterpene glycosides were isolated from Astragalus angustifolius Lam., together with five known triterpene glycosides. Their structures were established by the extensive use of 1D and 2D-NMR experiments along with ESIMS and HRMS analysis. Compounds 1-3 are glycosides of cycloastragenol, while compounds 4-6 show the C-24 epimer of cycloastragenol as aglycone, encountered for the first time in nature. All compounds were evaluated for their antiproliferative activity in Hela, H-446, HT-29, and U937 cell lines. Only compound 8 displayed a weak activity with IC50 values of 36 and 50 μM against Hela and HT-29 cell lines, respectively. Georg Thieme Verlag KG Stuttgart · New York.

Studies on isolation and structural identification of saponins from the herb Hylomecon japonica and their bioactivities

Three undescribed oleanane type triterpenoid saponins (1–3), along with one known saponin (4) were isolated from the whole herb of Hylomecon japonica. Their structures were elucidated by analysis of 1D and 2D-NMR (1H–1H COSY, HSQC, and HMBC) spectroscopic data, mass spectrometry (HR-ESI-MS) and chromatographic date (GC and LC) as 3-O-β-D-glucopyranosyl-(1 → 2)-β-D-glucuronopyranosyl gypsogenin 28-O-β-D-galactopyranosyl-(1 → 3)-[β-D-xylopyranosyl-(1 → 4)]-α-L-rhamnopyranosyl-(1 → 2)-β-L-arabinopyranosyl ester (1), 3-O-β-D-galactopyranosyl-(1 → 2)-β-D-glucuronopyranosyl gypsogenin 28-O-α-L-arabinopyranosyl-(1 → 3)-[β-D-xylopyranosyl-(1 → 4)]-α-L-rhamnopyranosyl-(1 → 2)-β-L-arabinopyranosyl ester (2), 3-O-β-D-galactopyranosyl-(1 → 2)-β-D-glucuronopyranosyl gypsogenin 28-O-β-D-galactopyranosyl-(1 → 3)-[β-D-xylopyranosyl-(1 → 4)]-α-L-rhamnopyranosyl-(1 → 2)-β-D-galactopyranosyl ester (3), 3-O-β-D-galactopyranosyl-(1 → 2)-[α-L-arabinopyranosyl-(1 → 3)]-β-D-glucuronopyranosyl gypsogenin 28-O-β-D-glucopyranosyl-(1 → 3)-[β-D-xylopyranosyl-(1 → 4)]-α-L-rhamnopyranosyl-(1 → 2)-β-D-fucopyranosyl ester (4). All saponins possess a partial sequence β-D-galactopyranosyl-(1 → 2)-β-D-glucuronopyranosyl at C-3 of the aglycon. Compound 1 has cytotoxic activity against human colon cancer cell lines HT29, 3 against human gastric cancer cell lines AGS, and 4 against human lung cancer cell lines A549, AGS and HT29. Among them, compounds 3 and 4 showed significant inhibitory effect against AGS with IC50 value of 6.01 ± 1.4 μM, 3.66 ± 1.8 μM, respectively. These results represent a contribution to the chemotaxonomy of the saponins of Hylomecon japonica and their bioactivities.
