Abstract
Free radical scavenging and tyrosinase inhibition activity of thirteen aromatic oils from Thai medicinal plants were investigated.
A stable free radical DPPH (1, 1-diphenyl-2-picryhydrazyl) was used in the free radical scavenging assay and mushroom tyrosinase enzyme was used in the tyrosinase inhibition test.
The two assays were performed in 96-well plates and the absorbance measured by a well reader.
Betel vine and holy basil oils gave the highest free radical scavenging activity with percent residual rate of absorbance (%RRA) of
15%, which is comparable to vitamin E and vitamin C, widely used in antiwrinkle cosmetics.
Kaffir lime leaf and fruit peel oils showed the highest tyrosinase inhibition activity of 86.8 and 100%, respectively, which is similar in potency to kojic acid, a popular ingredient in whitening cosmetics.
This study demonstrated the potential use of aromatic volatile oils extracted from Thai medicinal plants in commercial cosmetics.
