Antioxidant properties of butein isolated from Dalbergia odorifera

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1998
The antioxidant properties of butein, isolated from Dalbergia odorifera T. Chen, were investigated in this study. Butein inhibited iron-induced lipid peroxidation in rat brain homogenate in a concentration-dependent manner with an IC50, 3.3+/-0.4 microM. It was as potent as alpha-tocopherol in reducing the stable free radical diphenyl-2-picrylhydrazyl (

Melanogenic mechanism of ethanolic extract of Dalbergia odorifera

Molecular & Cellular Toxicology, 2017
Vitiligo and hair graying are acquired chronic hypopigmentary disorders of the skin. This study was carried out to investigate the effect of ethanolic extract of D. odorifera (DOE) on melanogenesis and determine its mechanism of action in B16F10 mouse melanoma cells and human epidermal melanocytes. DOE increased melanin content levels. It also enhanced
