Description: The inhibitory effect of a 50% ethanol extract obtained from the dried leaves and the bark of Myrica rubra, was investigate in vitro on melanin biosynthesis which is closely related to hyperpigmentation. These extracts inhibited tyrosinase activity which converts dopa to dopachrome in the biosynthetic process. Furthermore, the extracts inhibited the production of melanin from dodopachrome by autoxidation and also showed superoxide dismutase (SOD)-like activity. After bioassay-guided fractionation, quercetin, myricetin and myricetin 3-O-rhamnoside were isolated from the leaves. Function: 1. Improving the microcirculation and prophylaxis of artery cirrhosis; 2. Adjusting cholesterol level; 3. Decreasing blood sugar; 4. Protecting liver; 5. Anti-inflammation and anti-infection; 6. Acting as inhibitor of matrix metalloproteinas 7. A good dyeing agent.
