We isolated several stilbene compounds including rhaponticin (3',5-dihydroxy-4'-methoxystilbene 3- O-beta- D-glucopyranoside) from extracts of rhubarb rhizomes. These compounds showed significant hypoglycemic effects in streptozotocin (STZ)-induced type 1 diabetic rats and mice. In this study, we investigated the effect of rhaponticin

Rhaponticin (RHA) possesses a variety of pharmacological activities including potent antitumor, antitumor-promoting, antithrombotic, antioxidant and vasorelaxant effects. In the solvation effect, RHA exhibited bathochromic shift in emission spectra with the increasing solvent polarity. The binding between RHA and HSA was

Rhaponticin (RH) possesses a variety of pharmacological activities including potent antitumor, antitumor-promoting, antithrombotic, antioxidant and vasorelaxant effects. The fundamental photophysics of RH is not well understood. In this work, solvent effect on the photoluminescence behavior of RH was studied by

The official rhubarb species have frequently been investigated for their hydroxyanthraquinone components and associated pharmacological properties. However, other unofficial rhubarb species were rarely studied until polyhydroxystilbenes (PHS), which commonly occur in the unofficial rhubarb, revealed a range of potential bioactivities.

Rhapontigenin, an aglycone of rhapontin, was produced by biotransformation and we investigated its antifungal activity against Candida albicans, one of the most important opportunistic fungal pathogens. Rhapontigenin is found to have, in vitro, inhibitory activity with a minimal inhibitory concentration
