Abstract:Objective To study the whitening activity of ethanol extracts of several traditional Chinese medicine, and to provide experimental basis for the development of whitening products of traditional Chinese medicine. Methods Nine traditional Chinese medicine including lesser galangal rhizome, common bletilla rubber, dahurian angelica root, sappan wood, largehead atractylodes rhizome, Radix Arnebiae, argy wormwood leaf, purslane herb, and medicine terminalia fruit were extracted with 70% ethanol. Vitamin C and arbutin were used as positive control drugs. In vitro tyrosinase inhibition test was employed to compare the bioactivity of different drugs. Results The inhibition rate of traditional Chinese medicine medicine terminalia fruit was (51.43±2.52)%, was higher than (46.34±6.32)% of arbutin. Artemisiae Argyi, Herba Portulacae also have good tyrosinase inhibity, the inhibition rates were (22.88±7.99)% and (13.07±11.98)%, respectively. However, the other Chinese medicine hardly inhibited tyrosinase activity. Conclusion The ethanol extracts of medicine terminalia fruit and argy wormwood leaf have certain inhibitory activities on tyrosinase, which can be further studied as whitening tradiational Chinese medicine.
