  • 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.

  • In this study, the antioxidative effect, cellular protective effect and inhibitory effect on tyrosinase of Cosmos bipinnatus extracts were investigated. The ethyl acetate fraction of Cosmos bipinnatus flower extract ($11.48\;{\mu}g$/mL) showed more excellent free radical (1,1-diphenyl-2-picrylhydrazyl radical, DPPH) scavenging activity (FSC50) than those of leaf and stem extracts ($17.45\;{\mu}g$/mL). Reactive oxygen species (ROS) scavenging activity (OSC50) of Cosmos bipinnatus extracts on ROS generated in $Fe^{3+}$-EDTA/H2O2 system were investigated using the luminol-dependent chemiluminescence assay. The ethyl acetate fraction of Cosmos bipinnatus flower extract ($0.56\;{\mu}g$/mL) showed 3 times more excellent ROS scavenging activity than L-ascorbic acid ($1.50\;{\mu}g$/mL). The protective effects of the ethyl acetate fractions of extracts from different parts of Cosmos bipinnatus on the rose-bengal sensitized photohemolysis of human erythrocytes were investigated. The ethyl acetate fractions of leaf and stem extract and flower extracts suppressed photohemolysis in a concentration dependent manner ($10\sim50\;{\mu}g$/mL). The inhibitory effect of ethyl acetate fraction of Cosmos bipinnatus flower extract ($62.75\;{\mu}g$/mL) on tyrosinase was investigated to assess the whitening efficacy. The ethyl acetate fraction of Cosmos bipinnatus flower extract showed 3.5 times higher tyrosinase inhibitory effect than arbutin ($226.88\;{\mu}g$/mL) known as an effective whitening agent. These results indicate that fractions of Cosmos bipinnatus extracts can function as antioxidants in biological systems, particularly skin exposed to UV radiation by scavenging $^1O2$ and other ROS, and protect cellular membranes against ROS. Fractions of Cosmos bipinnatus extracts can be applicable to new functional cosmetics for antioxidant and whitening.

  • In this study, the whitening and antioxidant effects of the extracts from Hydrangea petiolaris (H. petiolaris) leaves was confirmed, and the chemical structure was identified by separating the active ingredients. In the whitening tests using α-MSH stimulated B16F10 melanoma cells, the n-hexane (Hex) fraction inhibited the cellular melanogenesis and intracellular tyrosinase activities without causing cell toxicity. In addition, the Hex fraction reduced expression of tyrosinase and TRP-2 protein. Upon the anti-oxidative studies by DPPH and ABTS+ radicals, potent radical scavenging activities were observed in the ethyl acetate (EtOAc) fraction. Also, for the cellular protective effects on HaCat keratinocytes damaged by H2O2, the EtOAc fraction indicated protective effects against oxidative stress. Eight phytochemicals were isolated from the extract of H. petiolaris leaves; ethyl linoleate (1), ethyl linolenate (2), 1-linoleoyl glycerol (3), 1-linolenoyl glycerol (4), epi-catechin (5), afzelin (6), quercitrin (7), hyperin (8). Among the isolates, the compounds 5 - 8 showed DPPH and ABTS+ radical scavenging activities. The contents of quercitirin, a major isolated in this extract, determined by HPLC analysis were confirmed to be about 31.3 mg/g for the 70% ethanol extract and 169.8 mg/g for the EtOAc fraction. Based on these results, it was suggested that the extract from H. petiolaris leaves could be potentially applicable as whitening and anti-oxidative ingredients in cosmetic formulations.

  • The purpose of this study was to investigate the applicability of the Psidium guajava leaf extract as a whitening functional cosmetic material. We measured DPPH radical scavenging activity, intracellular ROS, cytotoxicity in B16F10 melanoma cells and cytoprotective effect on ultraviolet A, in vitro tyrosinase inhibitory effect and melanin biosynthesis inhibitory effect. The antioxidative effect was confirmed through high DPPH radical scavenging activity and intracellular ROS activity inhibition measurement of the Psidium guajava leaf extract. The survival rate of B16F10 melanoma cells was more than 98% at all concentrations, and the cytoprotective effect from ultraviolet ray A was found to increase in a concentration-dependent manner. In addition, in vitro tyrosinase activity inhibitory effect of 10% and melanin biosynthesis inhibitory effect of 20% were observed. Through less toxicity for B16F10 melanoma cell, high antioxidant activity, inhibition of tyrosinase activity and melanin biosynthesis inhibitory effect, we confirmed the possibility of developing the Psidium guajava leaf extract as a whitening functional cosmetic material with a safe and excellent whitening effect.

  • Hyperpigmentation on face is a highly anxiety-producing symptom, especially for women from the aspect of beauty. Pigmentation of the skin is related to the amount of melanin that provides protection against UV radiation. In vivo reflectance confocal microscopy is a non-invasive imaging tool allowing visualization of the skin without tissue alteration, by placing a microscopy directly on the living skin. The aim of this study was to develop the new evaluation method of whitening effects using in vivo reflectance confocal microscopy and to validate other instruments for measuring skin colors, and UV-induced hyperpigmentation was elicited on the inside skin of the forearm. It suggested that the new method for whitening effects using the confocal microscopy was useful to evaluate the de-pigmentation products and to easy for understanding to customers.

  • To develop a new whitening agent for cosmetics, we investigated the inhibitory effects of biochanin A on melanogenesis. The biochanoin A is an active component in the extracts of Dalbergia odorifera T. Chen. It reduced melanin contents of B16F1 melanoma cells in a dose-dependent manner and decreased to about 48% at a concentration 10 ${\mu}g/mL$. It also inhibited the expression in microphthalmia associated transcription factor (MITF), Tyrosinase, Tyrosinase related protein 1 (Trp-1), and Tyrosinase related protein 2 (Trp-2) in melanocytes. The results suggested that biochanin A has considerable potential as a cosmetics ingredient with a whitening effect.

  • To investigate the natural cosmetic ingredients of Benincasa hispida seed extract on skin care, we measured anti-oxidant and anti-inflammatory, and whitening effect. DPPH free radical scavenging activity was increased in a dose-dependent manner. The total phenolic content was higher in methanol extract (22.42±0.002 mgGAE/g) than water extract (9.77±0.002 mgGAE/g). MTT assay was demonstrated that the seed extract did not have a cytotoxic effect in RAW264.7 and B16F10 cell lines. We also examined to find out the inhibitory activity on NO production and secretion of TNF-α cytokine in LPS-induced RAW264.7 cells. In B16F10 melanoma cells, the seed extract significantly suppressed α-MSH induced melanin synthesis. Furthermore, westernblot analysis revealed that methanol extract dramatically downregulated the expression level of MITF, TRP-1 and TRP-2. Taken together, the B. hispida seed extract posses anti-oxidant, anti-inflammatory and skin whitening activities, which might provided its functional efficacy in cosmetic materials.

  • Arbutin is a glycosylated hydroquinone found at high concentration in certain plants capable of surviving extreme and sustained dehydration. It has been reported to have an inhibitory effect of melanogenesis and to be hydrolyzed easily to yield glucose and hydroquinone by ${\beta}-glucosidase.$ While hydroquinone also has an anti-melanogenic effect, however, is carefully used as a topical whitening agent because of side effects. The present study was undertaken to examine the inhibitory effect of an whitening agent containing arbutin and ${\beta}-glucosidase$ on UV radiation induced pigmentation in human skin. Experimental subjects were UVB-irradiated on the back. UVB-irradiated areas were assigned to three groups: arbutin and ${\beta}-glucosidase$ treated group, vehicle control, and no-application control. Arbutin and ${\beta}-glucosidase$ treatment inhibited pigmentation by 50.17 percent, compared with the controls (N : 10: P<0.05). These results suggest that the whitening agent containing arbutin and ${\beta}-glucosidase$may be used as an agent to inhibit melanin formation induced by UV radiation.
