Three new phenylethanoid glycosides, incanoside C, incanoside D and incanoside E were isolated together with one known glycoside, beta-D-fructofuranosyl-alpha-D-(6-O-[E]-sinapoyl) glucopyranoside from the whole plant of Caryopteris incana (THUNB.) Miq. On the basis of chemical and spectral analyses, the structures of the new compounds were elucidated to be 1-O-(3,4-dihydroxyphenyl)ethyl-O-beta-...

Three new compounds, including a sesquiterpenoid glucoside gallate, 2 Z,4 E,1' R,2' S,4' R,6' S-dihydrophaseic acid 4'-O-(6''-O-galloyl)-β-D-glucopyranoside (1), two new phenolic glucoside gallates, 4-hydroxy-3,5-dimethoxybenzoic acid 4-O-(6'-O-galloyl)-β-D-glucopyranoside (2) and 3,4-dimethoxyphenol 1-O-(6'-O-galloyl)-β-D-glucopyranoside (3), together with eight known compounds (4-11), have be...

Three new spirostanol steroidal oligoglycosides, together with a known oligoglycoside, were obtained from the seeds of Allium tuberosum after enzymatic hydrolysis of furostanol saponin fraction by beta-glucosidase. On the basis of spectroscopic analysis, the structure of new spirostanol oligoglycosides were elucidated as (25S)-spirost-5-ene-2alpha,3beta-diol 3-O-alpha-L-rhamnopyranosyl-(1-->4)-...

Studies on the chemical constituents of roots of Urtica triangularis HAND-MASS have led to the isolation of four new compounds. The structures, including the absolute configurations, of these constituents have been elucidated through spectral studies including (1)H-NMR, (13)C-NMR, 2D-NMR experiments (heteronuclear single-quantum coherence, heteronuclear multiple bonding connectivity and nuclear...

Two new phenolic glycosides, named gnaphaffine A and B (compounds 1 and 2), were isolated from Gnaphalium affine. together with six known compounds, including caffeic acid (3), everlastoside L (4), isorhamnetin-7-O-β-D-glucopyranoside (5), quercetin- 3-O-β-D-glucopyranoside (6), scutellarein-7-O-β-D-glucoside (7) and api-genin-7-O-β-D- glucopyranoside (8). Their structures were elucidated by sp...

Two new phenylethanoid glycosides integrifoliosides A (2) and B (3), along with a known phenylethanoid glycoside alyssonoside (1) and a flavone glucoside chrysoeriol-7-O-beta-D-glucopyranoside (4) were isolated from the aerial parts of Phlomis integrifolia. The structures of the new compounds were identified as 3,4-dihydroxy-beta-phenylethoxy-O-beta-D-apiofuranosyl-(1 --> 4)-alpha-L-rhamnopyran...

The phytochemical investigation of the methanolic extract of the leaves of Salvadora persica afforded five known compounds identified as kampferol-3-O-β-glucopyranoside, Kaempferol-3,7di-O-β-glucopyranoside, quercetin-3',7-dimethylether, isobiflorin (5,7–dihydroxy-2methylchromone-8-C-β-glucopyranoside), biflorin (5,7–dihydroxy-2-methylchromone-6-C-βglucopyranoside), as well as a new cytotoxic c...

One triterpenic acid (ursolic acid), one phenolic acid (rosmarinic acid), and four flavonoids (luteolin, luteolin 7-O-(6”-feruloyl)-β-glucopyranoside, luteolin 5-O-β-glucopyranoside, and luteolin 7-O-β-glucuronide) were isolated from the aerial parts of Thymus sipyleus subsp. sipyleus var. sipyleus and identified by spectroscopic methods. In vitro lipid peroxidation inhibition effects of the co...

Five new oleanane-type triterpene saponins including steganogenin 3-O-β-D-glucopyranoside (1), steganogenin 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranoside (2), steganogenin 3-O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranoside (3), chichipegenin 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranoside (4) and chichipegenin 3-O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranoside (5), along with four known olean...

Viscum album L. has been used in the indigenous systems of medicine for treatment of headache and some inflammatory diseases. In order to evaluate this information, antinociceptive and anti-inflammatory activities of the five flavonoids (5,7-dimethoxy naringenin or 4',6'-dimethoxy chalcononaringenin) derivatives, isolated from the ethyl acetate fraction of the extract from V. album ssp. album, ...
