syringa pinnatifolia/neoplasms

One new norlignan, noralashinol B (1), and one new natural product, proposed noralashinol C (2), were isolated in a continuous phytochemical investigation on the stem barks of Syringa pinnatifolia. Their structures were elucidated based on the analysis of spectroscopic data, including mass

Phytochemical investigation of the twigs of Syringa oblata var. diatata led to the isolation of two new secoiridoid glucosides, dilatioside A-B (1-2), along with thirteen known ones (3-15). The structures were determined by spectroscopic methods including one and two dimensional (1- and 2D-) NMR

The aim of the present study was to examine the effects of verbascoside (VB) in rats subjected to experimental colitis. Colitis was induced in rats by intracolonic instillation of 2,4 dinitrobenzene sulfonic acid (DNBS; 25 mg/rat). VB was administered daily per os (0.2 and 2 mg/kg) 4 days after DNBS

Cytotoxic compounds, oleuropein (1) and a phenylethanoid glycoside (2) were isolated from the stem bark of Syringa velutina KOM. along with coniferylaldehyde 4-O-glucoside, syringin, ligstroside, (+)-syringaresinol 4-O-glucoside, (+)-medioresinol 4"-O-glucoside and (-)-olivil 4"-O-glucoside.
