Objective:
To study the effects of 21 kinds of traditional Chinese medicines on tyrosinase.
Methods:
The catalytic reactive velocity of tyrosinase was determined by vision spectrophotometry so as to evaluate the upregulation of traditional Chinese medicines extracts.
Results:
21 time-curves of catalytic reaction of tyrosinase were obtained.
Conclusion:
13 kinds of traditional Chinese medicines extracts in vitro showed a upregulation to tyrosinase activity (P < 0.01). Scutellaria baicalensis and Cremastra appendiculata showed a better upregulation to tyrosinase activity.
