Objectives : This study is designed to clarify whitening, anti-inflammatory effect of fractions extracted from the mixture of Phaseolus radiatus L. and ethanol. Methods : In this experiment, we were intended to reveal whitening, anti-inflammatory effect of fractions extracted from the mixture of Phaseolus radiatus L. and ethanol. The whitening activity was confirmed by UV blocking activity, tyrosinase inhibiting activity, and melanin formation inhibiting activity. Anti-inflammatory activity is confirmed by measurement of cytotoxicity level by MTT assay and measurement of Cytokine expression, which is the main mediator of inflammation reaction. Results : As a results, overall activity was high in the ethyl acetate fraction. Tyrosinase inhibitory activity was less than 20% at all concentrations, but the activity to inhibit melanin self-production was higher than that of ethyl acetate fraction at $32.19{\pm}2.79%$ at $100{\mu}g/m{\ell}$. And ethyl acetate fraction had a relatively high UV blocking activity. In the anti-inflammatory test, the concentration-dependent activity was shown, and the chloroform and ethyl acetate fractions showed significant NO production inhibitory activity. Cytokine expression was superior to that of the final stage of B cell differentiation, and cell viability was over 80% except for the chloroform fraction at the concentration of $200{\mu}g/m{\ell}$. Conclusions : The results of this experiment confirmed the whitening effect and anti-inflammatory effect of Phaseolus radiatus L.'s extracts and fractions and report the possibility of application as external medicine.

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.

The demand for natural substances with anti-melanogenic activity is increasing due to the recent interest in skin whitening. Intensive investigation on the culture broth of Streptomyces sp. SCO-736, a marine bacterium from the Antarctica coast, has led to the isolation of a new natural product named antaroide (1). The chemical structure was established through the interpretation of MS, UV, and NMR spectroscopic data. Antaroide is a nine-membered macrolide with lactone and lactam moieties. To investigate its applicability in skin whitening cosmetics, its anti-melanogenic activity in B16F10 murine melanoma cells was examined. As a result, antaroide displayed strong inhibitory activities against melanin synthesis and also attenuated the dendrite formation induced by the α-melanocyte stimulating hormone (α-MSH). Antaroide suppressed the mRNA expression of the melanogenic enzymes such as tyrosinase, TRP-1 and TRP-2. This suggests that it may serve as a transcriptional regulator of melanogenesis. Collectively, the discovery of this novel natural nine-membered macrolide and its anti-melanogenic activity could give new insights for the development of skin whitening agents.

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.

In this study, we investigated whitening and anti-inflammatory constituents from a watermelon (Citrullus lanatus, C. lanatus) vines (leaves and stems). As anti-melanogenesis and anti-inflammatory activities were screened for the ethanol extract and solvent fractions, n-hexane (n-Hex) and ethyl acetate (EtOAc) fractions showed the most potent activities. Three constituents were isolated from the n-Hex and EtOAc fractions of C. lanatus; ${\alpha}-linolenic$ acid (1), sigmast-7-en-O-${\beta}$-D-glucopyranoside (2), 1-feruloyl-${\beta}$-D-glucopyrinoside (3). The chemical structures of the isolated compounds were elucidated based on the spectroscopic data including $^1H$ and $^{13}C$ NMR spectra, as well as comparison of the data to the literature values. Whitening and anti-inflammatory effects were studied for the isolated compounds. Upon the anti-melanogenesis tests using ${\alpha}-MSH$ stimulated B16F10 melanoma cells, the compounds 1 and 3 inhibited the cellular melanogenesis and intracellular tyrosinase activities effectively. For the anti-inflammation tests using lipopolysaccharide (LPS)-induced RAW 264.7 cells, the isolates 1 and 3 were determined to decrease the production of nitric oxide (NO) and pro-inflammatory cytokines ($TNF-{\alpha}$, IL-6). Based on these results, C. lanatus vines extract could be potentially applicable as whitening and anti-inflammatory ingredients in cosmetic formulations.

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.

In this study, extracts from Caryopteris incana Miq. (C. incana) were investigated to assess anti-oxidation, skin-whitening and anti-wrinkle activity. The total phenolic compounds of C. incana extracts with water and 80 % ethanol showed 7.69 and 12.50 mg/g respectively. Antioxidation activity of C. incana extracts was measured by using 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2-azinobis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS), protection factor (PF), and Thiobarbituric acid reactive substances (TBARs). At concentration of $200{\mu}g/mL$, the DPPH free radical scavenging activity of water and ethanol extracts were 84 and 92 %, respectively. ABTS radical scavenging activity of water and ethanol extracts were both at approximately 99 %. Antioxidant PF of water and ethanol extracts were 1.56 PF and 1.67 PF, respectively. The TBARs of water and ethanol extracts were 62 and 82 %, respectively. In anti-wrinkle and skin-whitening activity, 80 % ethanol extract had more outstanding effect than water extract at concentration of $200{\mu}g/mL$. The levels of elastase and collagenase inhibitory activity related with anti-wrinkle were 58 and 89 % in ethanol extract. The tyrosinase inhibitory activity related with skin-whitening was 13 % in ethanol extract. The astringent effect of ethanol extract was 50 %. Throughout the results, C. incana extracts showed an excellent effect on anti-oxidation, skin-whitening and anti-wrinkle activity. Therefore, C. incana extracts can be used as a new material for cosmetics.
