Inhibitory effect of Elephantopus mollis H.B. and K. extract on melanogenesis in B16 murine melanoma cells by downregulating microphthalmia-associated transcription factor expression.

In this study, the inhibitory effect of Elephantopus mollis H.B. and K.

A novel melanin inhibitor: hydroperoxy traxastane-type triterpene from flowers of Arnica montana.

We isolated a novel inhibitor of melanin biosynthesis from the flowers of Arnica montana L. (Compositae), and identified it as a traxastane-type triterpene (3beta,16beta-dihydroxy-21alpha-hydroperoxy-20(30)-taraxastene) [1] by means of 1D or 2D-NMR and liquid chromatography/high-resolution mass spectrometry (LC-HR-MS). Compound [1] at the concentration of 0.
