In order to obtain the basic data fer the processing adaptability of Korean figs(Ficus carica L.), physicochemical analyses were carried out with Korean common type figs in the different ripening stages. Moisture contents decreased, but the contents of protein, fat carbohydrate and soluble solids increased according to the ripening of fruits. K was detected as the most abundant one of all the minerals and Ca, Mg, Na, Fe, Mn, Zn and Cu were the next in order. The mineral contents decreased slightly with ripening. Especially, Ca, Mg, U, Fe and Zn were higher in the unripened H stage figs. The antioxidative activity was assayed with water and methanol extracts from ripened figs by the DPPH radical scavenging ability. The antioxidative activities of Korean figs were relatively high and increased in a dose dependent manner. The methanol extract showed the higher antioxidative activity than the water one. Therefore, the methanol was the better solvent than water for the antioxidative compounds. These results suggested that Korean figs are relatively the good sources of minerals, especially the Ca and the antioxidative compounds.

Whitening is inhibitory activity of the melanin synthesis of melanocytes. Recently, whitening materials have been developed on natural materials because of its side effects on skin. Figs (Ficus Carica L.) is a fruit belonging to the Moraceae family and whitening activity was reported in focusing on the fig's stem and leaf components, but whitening activity of the figs fruit was not known. Thus, in this study, we tried to observe its anti-melanogenesis as well as antioxidant and anti-inflammation. The radical scavenging activity of figs fruits extract (FFE) was observed as the level of 34.52±1.98%/60.71±1.26% compared to the control in the its maximum concentration in the DPPH/ABTS assay. Cytotoxicity of FFE was observed at 10% concentration by CCK8 assay, so the maximum concentration was set at 5% and applied to all experiments. FFE concentration dependently decreased NO production associated with inducible nitric oxide synthase, cyclooxygenase-2, interleukin-6 and tumor necrosis factor-α gene expression, these strongly suggesting anti-inflammatory activity. In melanin contents assay, FFE significantly down-regulated melanin production in α-MSH-stimulated B16F10 cell as well as tyrosinase inhibition in vitro. In addition, FFE decreased the Microphthalmia-associated transcription factor (MITF) mRNA expression about 94.34% compared to the α-MSH treatment group in RT-PCR. Finally, FFE significantly reduced the MITF, cAMP response element-binding protein and tyrosinase protein expression in the α-MSH stimulated B16F10 cell. Through these results, we found that FFE can not only directly inhibit tyrosinase enzyme activity but also suppress melanogenesis through regulation of MITF gene expression in α-MSH signal transduction.

The antibacterial activities of methanol extract and systematic solvent fractions( -hexane, chloroform, ethyl acetate, and butanol) from Korean common type figs at different ripening stages were tested by the broth dilution method against 8 representative food-poisoning bacteria- : L. monocytogenes, S. aureus, S. enteritidis, E. coli O157:H7, E. coli, Y. enterocolitica, V. parahaemolyticus, and S. typhimurium. The methanol extracts of unripened I and II showed stronger activity than that of the ripened figs especially against L. monocytogenes, S. enteritidis, E. coli O157:H7, Y. parahaemolyticus and S. typhimurium in 10 mg/mL. The systematic solvent fractions showed stronger antibacterial activities than the methanol extract, even al the lower concentrations. The hexane fraction of ripened figs showed higher growth inhibition than those of unripened I and II against L. monocytogenes, E. coli O157:H7, Y. enterocolitica and V. parahaemolyticus. The chloroform fraction showed strong antibacterial activity in all ripening stages against E. coli O157:H7 and V. parahaemolyticus. The butanol fraction showed better inhibition activity in unripened I and II than in the ripened figs. The hexane and chloroform fractions showed inhibition activity of more than $75\%$ against E. coli O157:H7, V. parahaemolyticus in 0.5 mg/mL. Each fraction showed a little different antibacterial activity according to the ripening stages of the fruits and the tested strains. Especially, figs in the unripened II stage revealed superior activity relatively and the hexane and chloroform fractions revealed the strongest activity, followed by the butanol fraction, while the ethylacetate and water fractions hardly showed any activity.

Figs has known to have antioxidant, whitening, anti-inflammatory, and antibacterial effects in their leaves, roots, stems, latex, and fruits. In order to develop cosmetic materials based on natural products, we have studied on the skin activity of the ficin in latex as well as the whitening function of the fruit extract with 70% ethanol, and used it as a raw material for released cosmetic product. However, there is little research on the demand for the development of new eutectic solvent extraction methods and its ability to control skin inflammation and psoriasis regulation. Thus, in this study, we evaluated the effectiveness of fig fruit extracts and fractions using eutectic solvent extraction for skin inflammation control and psoriasis. First, fig fruits were extracted under optimal eutectic solvent conditions and fractionated with n-hexane, dichloromethane, ethyl acetate, and butanol. First, the antioxidant activity and inhibition of nitric oxide (NO) production were confirmed in mouse macrophage RAW264.7 cells. In addition, as a result of observing the mRNA expression through RT-PCR, pro-inflammatory cytokines such as TNF-α, IL1α, and IL-1β were suppressed significantly in the hexane, dichloromethane, and ethyl acetate fractions. In addition, it was confirmed in TNF-α stimulated HaCaT keratinocyte model. Finally, chemokine CC motif ligand 20 (CCL20), marker gene of human psoriasis skin disease, was significantly suppressed in the hexane, dichloromethane, and ethyl acetate fractions. These results suggested its anti-inflammatory and skin soothing effect and the possibility of development as an excellent skin soothing natural cosmetic material in the future through future clinical trials.
