Inhibitory Effects of Saussurea involucrata. Against Melanogenesis of Mouse-Derived Melanocyte Cells

Abstract

Extracts and fractions from the aerial parts of herbal materials of Saussurea involucrata. Kar et Kir ex Maxim (Compositae) were investigated for their whitening activity against mouse-derived immortalized melanocyte cell line. The extract of wild herbs (FS2) possessed a better inhibition (28.2% growth) against melanin cells than that (46.7%) of cultivated herbs (FS1). The whole extracts and middle-polar partitioning fraction show the inhibitory effects, whereas the water-soluble parts show a poor activity in the same assay.
