Three new triterpenoid saponins, named isoescins VIIa (1), VIa (2), and VIIIa (3), were isolated from the seeds of Aesculus turbinata and identified by spectroscopic analysis and chemical hydrolysis. Their structures were established as 21β-O-tigloyl-28-O-acetylprotoaescigenin 3β-O-[β-d-galactopyranosyl(1 → 2)][β-d-glucopyranosyl(1 → 4)]-β-d-glucopyranosiduronic acid (Isoescin VIIa, 1), 21β-O-(2-methylbutyryl)-28-O-acetylprotoaescigenin 3β-O-[β-d-glucopyranosyl(1 → 2)] [β-d-glucopyranosyl(1 → 4)]-β-d-glucopyranosiduronic acid (Isoescin VIa, 2), and 21β-O-angeloyl-28-O-acetylbarringtogenol C 3β-O-[β-d-glucopyranosyl(1 → 2)] [β-d-glucopyranosyl(1 → 4)]-β-d-glucopyranosiduronic acid (Isoescin VIIIa, 3). 相似文献

Two new triterpenoid saponins, caraganins A and B (1 and 2), structurally characterized by a 22-oxo group, were isolated from the seeds of Caragana microphylla Lam., together with their n-butyl esters as artifacts (1a and 2a). Their structures and configurations were elucidated by detailed spectroscopic analyses on the basis of NMR, IR, and MS data. Compounds 1a and 2a exhibited potent antibacterial activity against Staphylococcus aureus and Bacillus subtilis with minimum inhibitory concentration values ranging from 3.125 to 6.25 μg/ml. 相似文献

Bioassay-guided fractionation of an active n-BuOH extract of the whole plant of Ixeris sonchifolia, using a cytotoxicity assay, resulted in the isolation of three new triterpenoid saponins, ixeris saponins A (1), B (2), and C (3). On the basis of chemical evidence and extensive spectral studies, their structures were established as echinocystic acid 3-O-beta-D-glucopyranosyl(1-->3)-beta-D-glucopyranosyl(1-->3)-alpha- L-arabinopyranoside (1), 3-O-[bis[beta-D-glucopyranosyl(1-->2 and 1-->3)-alpha-L-arabinopyranosyl]]echinocystic acid 28-O-beta-D-glucopyranosyl ester (2), and 3- O-[beta-D-glucopyranosyl(1-->3)-beta- D-glucopyranosyl(1-->3)-alpha-L-arabinopyranosyl]-16alpha, 23-dihydroxyolean-12-ene 28-O-beta-D-glucopyranosyl ester (3). Compounds 2 and 3 showed significant cytotoxicity against cancer cell lines A375, L929, and HeLa with IC50 values ranging from 8.83 microM to 15.83 microM, while compound 1 was inactive against these three cell lines. 相似文献

Three new triterpenoid saponins, impatiprins A-C (1-3), together with a known triterpenoid (4) and two known triterpenoid saponins (5, 6), were isolated from the rhizomes of Impatiens pritzellii Hook. f. var. hupehensis Hook. f. The structures of 1-3 were determined by 1D and 2D NMR, FAB-MS techniques and chemical methods. Compounds 1 and 2 showed weak cytotoxicities against S-180, HeLa and HepG2 cell lines. 相似文献

Five new oleanane-type triterpenoid saponins, oleiferasaponins D1–D5 (1–5), were isolated from the defatted seeds of Camellia oleifera Abel. Their structures were elucidated by spectroscopic and chemical methods. The cytotoxic activities of compounds 1–5 were evaluated against five human tumor cell lines (HCT-116, HepG2, BGC-823, NCI-H1650, and A2780). Compounds 1–2 exhibited cytotoxic activity against five human cancer cell lines, with IC50 values ranging from 3.31 to 10.23 μM. Compounds 3–5 showed moderate cytotoxic activities toward the tested cell lines. 相似文献
