These compounds known for their anti-inflammatory action health benefits in preventing a wide range of disorders (e.g. cancer cardiovascular diseases). However, antimicrobial properties less investigated. A series 8 stilbenoid were synthesized antifungal activi...
Three stilbene trimers (gnemonols D, E, F) were isolated from the root of Gnetum gnemon. The structures were determined by spectroscopic analysis. In addition, the antioxidant activity of the compounds on lipid peroxide inhibition and super oxide scavenging activity were also investigated.
Cyperaceae is a cosmopolitan plant family with approx. 5000 species distributed worldwide. Several members of this are used in traditional medicines for the treatment different diseases. In last few decades, constituents great chemical diversity were isolated from sedges, and wide range biological activities detected either crude extracts or pure compounds. Among compounds, phenolic derivatives...
A new stilbene, 4-[(2"E)-7"-hydroxy-3",7"-dimethyloct-2"-enyl]-2',3,4',5-tetrahydroxy-trans-stilbene (1), and the known compound chlorophorin (2) were isolated from the heartwood of Chlorophora excelsa. Both 1 and 2 showed tyrosinase inhibitory activity with IC(50) values of 96 and 1.3 microM, respectively.
