Abstract
|
|
|
Background: The inhibitory effect of Rodgersia podophylla root extract on melanin production has been reported, however, the study on the optimal extraction conditions that increase melanin inhibitory activity has not yet been performed.
Methods and Results: In this study, we compared the melanin inhibitory activity of R. podophylla root extract obtained through different preprocessing and extraction methods. The melanin inhibitory activity was examined using Melan-A melanocytes. The results indicated that the inhibitory activity of R. podophylla roots collected in August was higher than that of the roots collected in May and November. Additionally, non-dried R. podophylla roots exhibited higher activity than dried roots, and the stirring extract was more active than the ultrasonic extract.
Conclusions: Collection of R. podophylla root when the temperature is high, without drying, and stirring extraction are considered to be the optimal extraction conditions for increased melanin inhibitory effect.
