  • Platycodon grandiflorum (balloon flower) root (Platycodi radix, PR) is used as a health supplement owing to its beneficial bioactive properties. In the present study, the anti-inflammatory, antioxidant, and whitening effects of deglycosylated platycosides (saponins) from PR biotransformed by pectinase from Aspergillus aculeatus were investigated. The bioactivities of the platycosides improved when the number of sugar moieties attached to the aglycone platycosides was decreased. The deglycosylated saponins exhibited higher lipoxygenase inhibitory activities (anti-inflammatory activities) than the precursor platycosides and the anti-inflammatory compound baicalein. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity of the pectinasetreated PR extract was higher than that of the non-treated PR extract. The trolox-equivalent antioxidant capacity (TEAC) assay showed improved values as the saponins were hydrolyzed. The tyrosinase inhibitory activities (whitening effects) of deglycosylated platycosides were higher than those of the precursor platycosides. Furthermore, 3-O-β-ᴅ-glucopyranosyl platycosides showed higher anti-inflammatory, antioxidant, and whitening activities than their precursor glycosylated platycosides. Therefore, 3-O-β-ᴅ-glucopyranosyl platycosides may improve the beneficial effects of nutritional supplements and cosmetic products.

  • This study was performed to improve antioxidant activities and skin-whitening effects of Rubus coreanus Miquel extracts by nano-encapsulation. R. coreanus was extracted at $60^{\circ}C$ and encapsulated by lecithin and gelagine. Nano-encapsulated extracts showed highest free radical scavengering effect as 97.62% in adding sample ($500\;{\mu}g/m{\ell}$), compared to the extracts from conventional processes. It was showed strong inhibition effect on melanin production test by Clone M-3 cells as 55.23%. High inhibitory potency on tyrosinase was also measured as 155.8% by adding nano-sample of 1 $mg/m{\ell}$. The improvement of biological activity was demonstrated by real time confocal microscope. We could consider that the water soluble extracts of R. coreanus could be definitely enhanced by nano-encapsulated as a potent natural resources for antioxidant and skin-whitening agent.

  • Background: The purpose of this study was to investigate whether Sibseonsan (SSS) is an effective antiinflammatory, anti-wrinkling, and whitening agent. Methods: To determine whether SSS had an anti-inflammatory effect, a murine macrophage cell line was used (RAW 264.7) and production of DPPH, NO, TNF-α, and PGE2 were measured. To ascertain potential anti-wrinkle effects of SSS in these cells, collagenase and elastase production were measured. To verify whether SSS had a whitening effect, tyrosinase activity and DOPA staining were performed using a melanoma cell line (B16/F10). Results: There was no significant reduction in survival of SSS-treated RAW 264.7 cells, up to 400 ㎍/mL. Free radical scavenging (23.96 ± 1.85%) was observed in RAW 264.7 cells treated with SSS at a concentration of 400 ㎍/mL. The SSS treatment group (400 ㎍/mL) significantly inhibited NO production compared with the LPS stimulated treatment group. The SSS treatment of macrophage cells appeared to reduce production of TNF-α in a concentration dependent manner. There was a significant reduction in the concentration of PGE2 by about 25% in the SSS treatment (400 ㎍/mL) group (p = 0.05). Compared with the control, the production of collagenase and elastase in B16/F10 cells treated with SSS (400 ㎍/mL) was greater by 26.37% and 45.71%, respectively. The SSS treatment (400 ㎍/mL) group showed a significant reduction by about 17% in tyrosinase production in B16/F10 cells. The SSS treatment group showed little change in DOPA staining. Conclusion: SSS extract may be useful for the treatment and prevention of inflammatory diseases and may have anti-wrinkle and whitening effects. These results may support the use of SSS in clinical practice.

  • Dendrobium moniliforme (DM) is a valuable and versatile herbal medicine with the anecdotal claims of antioxidant and anti-inflammation. In the present study, we investigated the whitening and anti-wrinkling effects of DM under various conditions with B16F10 melanoma cells and human dermal fibroblasts. The DM extract inhibited melanin contents and tyrosinase activity in a dose-dependent manner, compared with untreated group. Treatment of the DM extract effectively suppressed the ${\alpha}$-MSH-stimulated melanin formation, tyrosinase activity and dendrite outgrowth. Moreover, the ${\alpha}$-MSH-induced mRNA expressions of tyrosinase-related protein-1 (TRP-1) and tyrosinase-related protein-2 (TRP-2) and protein expression of tyrosinase were significantly attenuated by DM treatment. We also investigated the DM increased the production of type I procollagen and inhibited TNF-${\alpha}$-induced mRNA expressions of MMP-1, -3 in the human dermal fibroblast. These results indicate that DM may be a great cosmeceutical ingredient for its whitening and anti-wrinkle effects.

  • 여성의 얼굴에 과색소침착이 발생하는 것은 불안감, 특히 미적인 요소에 있어서 많은 고민을 유발한다. 피부의 흑화는 자외선(UV)에 대하여 이를 방어하기 위한 기작으로 멜라닌의 양과 밀접한 관계가 있다. 이러한 피부의 구성성분을 관찰하기 위해, confocal scanning laser microscope (CSLM)은 피부에 직접 현미경 검사를 실시하여 어떠한 조직의 변화 없이 피부를 실시간으로 관찰할 수 있는 비침습적 이미지 장치이다. 본 연구에서는 자외선 조사를 통해 유도된 하박 내측 피부의 과색소침착을 유도하여, 다른 피부색을 평가하는 측정기기와 상관성을 분석하여, CSLM을 이용한 새로운 미백 평가방법을 제시하였다. CSLM을 활용한 미백 효능 평가법은 소비자가 보다 이해하기 쉽도록 미백 제품을 평가하는데 유용할 것으로 생각된다.
