Antioxidant, Anti-wrinkle and Whitening Effect of Fermented Extracts of Hwangryunhaedoktang

Hwangryunhaedoktang (HHT) has been traditionally used as a preventive and therapeutic medicine to treat enervation and diverse chronic diseases. This study was designed to compare the antioxidant, anti-wrinkle and whitening effects of HHT extract and its fermented extract by Leuconostoc mesenteroides (FHHT). FHHT was prepared by inoculation of L. mesenteroides after the extraction procedure with 70% ethanol. HHT and FHHT was investigated via high-performance liquid chromatography (HPLC). Simultaneous qualitative analysis of two bioacitive components, berberine and palmatine. was achieved by comparing their retention times (tR) and UV spectra with those of the standard components. Cell viability test results indicated that both HHT and FHHT were non-toxic. In DPPH radical scavenging ability, SC50 values of the FHHT was 68.85 ㎍/mL, which is more effective than HHT. Moreover, FHHT showed higher expression in production of procollagen type I than HHT. In nontoxic concentration range, FHHT showed strong melanin production inhibitory effect in α-melanocyte stimulating hormone (α-MSH)-stimulated B16F10 cell (IC50 = 9.82 μg/mL). These results suggested that fermented extracts of hwangryunhaedoktang had considerable potential as a cosmetics ingredient with an antioxidant and anti-wrinkle and whitening effects.
