Biological Activities
Compounds
Conditions
Willughbeia coriacea, specifically the bark part of its aerial root, demonstrates significant DPPH radical-scavenging activity of more than 70% at 100 microg/ml. This plant also exhibits tyrosinase inhibitory activity exceeding 40% when using both L-tyrosine and L-DOPA as substrates at 500 microg/ml. Furthermore, the extract of W. coriacea strongly inhibits the melanin production of B16 melanoma cells at a concentration of 200 microg/ml. These specific biological activities suggest that the plant possesses potent antimelanogenic properties. Such multifaceted effects highlight its potential utility in preventing melanin formation and managing oxidative stress.
Preparations
Parts used
Willughbeia coriacea has been identified as a promising candidate for developing new skin-whitening cosmetic ingredients. Research conducted in Central Kalimantan utilized the bark part of its aerial root to test for various medicinal properties. This specific plant part demonstrated significant DPPH radical-scavenging activity when screened against oxidative stress. Furthermore, the extract showed notable tyrosinase inhibitory activity using both L-tyrosine and L-DOPA as substrates. Most importantly, the aerial root extract effectively inhibited melanin production in B16 melanoma cells without exhibiting significant cytotoxicity.
