Two additional novel minor diterpene glycosides were isolated from the commercial extract of the leaves of Stevia rebaudiana Bertoni. The structures of the new compounds were identified as 13-{β-D-glucopyranosyl-(1?2)-O- [β-D-glucopyranosyl- (1?3)-β-D-glu

As part of our continuing study of apoptosis-inducing saponins from Cameroonian Albizia genus, one new triterpenoid saponin, named adianthifolioside J (1), together with the known gummiferaoside E (2), were isolated from Albizia adianthifolia stems. The s

Six undescribed oleanane-type saponins, named as Hylomeconosides L-Q, were isolated from the whole herb of Hylomecon Japonica, their structures were determined by analysis of 1D and 2D-NMR (1H–1H COSY, HSQC, and HMBC) spectroscopic data, mass spectrometry (HRESI-MS) and chromatographic data (GC and LC). Their structures were identified as 3-O-β-D-galactopyranosyl-(1 → 2)-β-D-glucuronopyranosyl gypsogenin 28-O-β-D-galactopyranosyl-(1 → 3)-α-L-rhamnopyranosyl-(1 → 2)-β-L-arabinopyranoside; 3-O-β-D-galactopyranosyl-(1 → 2)-β-D-glucuronopyranosyl gypsogenin 28-O-β-D-xylopyranosyl-(1 → 4)-α-L-rhamnopyranosyl-(1 → 2)-β-D-quinovopyranoside; 3-O-β-D-glucuronopyranosyl gypsogenin 28-O-β-D-xylopyranosyl-(1 → 3)-β-D-xylopyranosyl-(1 → 4)-α-L-rhamnopyranosyl-(1 → 2)-β-D-quinovopyranoside; 3-O-β-D-xylopyranosyl-(1 → 3)-β-D-glucuronopyranosyl gypsogenin 28-O-β-D-xylopyranosyl-(1 → 4)-α-L-rhamnopyranosyl-(1 → 2)-β-D-quinovopyranoside; 3-O-β-D-galactopyranosyl-(1 → 2)-[α-L-rhamnopyranosyl-(1 → 3)]-β-D-glucuronopyranosyl quillaic acid 28-O-β-D-xylopyranosyl-(1 → 3)-β-D-xylopyranosyl-(1 → 4)-α-L-rhamnopyranosyl-(1 → 2)-β-D-quinovopyranoside; 3-O-β-D-galactopyranosyl-(1 → 2)-[α-L-rhamnopyranosyl-(1 → 3)]-β-D-glucuronopyranosyl quillaic acid 28-O-β-D-xylopyranosyl-(1 → 3)-β-D-xylopyranosyl-(1 → 4)-α-L-rhamnopyranosyl-(1 → 2)-β-D-galactopyranoside. Hylomeconosides L-Q showed selective cytotoxicities against human cancer cell lines A549, AGS, HeLa, Huh 7, HT29 and K562. These results represent a contribution to the chemotaxonomy of the saponins of Hylomecon Japonica and their bioactivities.

A new compound, named arillatanoside E, which was elucidated as 3-O-β-D-glucopyranosyl presenegenin 28-O-β-D-xylopyranosyl-(1 - 3)-β-D-xylopyranosyl-(1 - 4)-α-L-rhamnopyranosyl-(1 - 2)-(4-O-acetyl)-β-D-fucopyranosyl ester, along with 11 known compounds was isolated from the ethanolic extract of the roots of Polygala arillata. The 11 known compounds were identified as oleanolic acid (2), 3′-E-3,4,5-trimethoxy cinnamoyl-6-benzoyl sucrose (3), trans-ferulic acid (4), trans-feruloyl-glucoside (5), feruloyl-glucoside (6), 2,4,6-trimethoxy-1-O-β-D-glycoside (7), 3-methoxy-4-hydroxybenzoic acid (8), monopentadecanoin (9), sinapic acid (10), p-hydroxybenzaldehyde (11), and palmitic acid (12). Among them, seven isolated compounds 1, 2, 4, 5, 7, 8, and 10 exhibited little cytotoxic activity on macrophage RAW 264.7 cells. Then, the inhibitory effects of 7 isolates on nitric oxide (NO) production in lipopolysaccharide-activated macrophages were evaluated. As a result, 3 compounds have significant anti-inflammatory activity, and they were arillatanoside E (1), oleanolic acid (2), and 2,4,6-trimethoxy-1-O-β-D-glycoside (7).
