- Abstract
- Mulberroside A was isolated from the ethanol extract of Mons alba roots. The enzymatic hydrolysis of mulberroside A with Pectinex (R) produced oxyresveratrol and oxyresveratrol-3-O-glucoside. We tested oxyresveratrol, oxyresveratrol-3-O-glucoside, and mulberroside A to determine whether they could inhibit ultraviolet B (UVB) irradiation-induced melanogenesis in brown guinea pig skin. Topical application of mulberroside A, oxyresveratrol, and oxyresveratrol-3-O-glucoside reduced the pigmentation in guinea pig skin. These compounds suppressed the expression of melanogenic enzymes tyrosinase, tyrosinase-related protein-1, and microphthalmia transcription factor. The anti-melanogenesis effect was highest with oxyresveratrol, intermediate with oxyresveratrol-3-O-glucoside, and lowest with mulberroside A. Mulberroside A is a glycosylated stilbene of oxyresveratrol; thus, the deglycosylation of mulberroside A resulted in enhanced inhibition of melanogenesis. Histological analysis with Fontana-Masson staining confirmed that these compounds significantly reduced the melanin content in the epidermis of UVB-irradiated guinea pig skin compared to the vehicle control. Thus, these compounds effectively reduced pigmentation and may be suitable cosmetic agents for skin whitening. (C) 2011 Elsevier Ltd. All rights reserved.
