Objectives : The present study was designed to investigate effects of mixed extract from korean medicinal herbs (MIX) on oxidation/reduction reaction-related and aging-related enzyme in vitro. Methods : We performed MTT assay, collagenase inhibition assay, elastase inhibition assay, tyrosinase inhibition assay, DPPH free radical scavenging assay, SOD-like activity and xanthine oxidase inhibition assay. Results : Recently, many studies have reported that elastin is also involved in inhibiting or repairing wrinkle formation, although collagen is a major factor in the skin wrinkle formation. The MIX showed 97% inhibition of collagenase activity, and 64% inhibition of elastase activity at 1 mg/ml concentration of MIX, next only to positive control, which indicate good efficacy for anti-wrinkle ingredient. Also it's treatment showed 34% inhibition of tyrosinase activity, to relate whitening effect, at the same dose of MIX. Antioxidant activities were determined by DPPH radical scavenging, xanthine oxidase (XO) inhibiting activity and SOD-like activity. Also these scavenging, XO-inhibiting and SOD-like activities were measured in 91%, 80%, and 63% inhibition, respectively, at a treated dose of 1 mg/ml, compare to control. Conclusions : These results suggest that possibility of mixed korean medicinal herbs as a functional ingredient for anti-wrinkle and whitening, anti-oxidation and anti-aging cosmetic formula.

Gryllus bimaculatus extract (GbE) have reported that anti-inflammatory activity by suppression of pro-inflammatory cytokines. However, the effects of fermented Gryllus bimaculatus extract (FGbE) have not yet been investigated. In this study, we evaluated the anti-inflammatory and anti-wrinkle effect of the fermented Gryllus bimaculatus extracts using Bacillus subtilis (JB PMB-18) in RAW264.7 cells. Both GbE and FGbE exerted no cytotoxic effects until 1000 ㎍/mL concentration. FGbE decreased NO production and decreased iNOS and COX-2 mRNA levels in a concentration-dependent manner. In addition, the protein production of inflammatory cytokines TNF-α, IL-1β and IL-6 was effectively reduced compared to the GbE. Inhibitory activities of elastase and collagenase associated with skin wrinkle improvement were measured to be 45% and 69%, respectively, at a concentration of 500 ㎍/mL in FGbE. From these results, FGbE can be used as a health functional food and skin functional cosmetic materials for preventing inflammatory diseases because it has excellent anti-inflammatory and anti-wrinkle effects.

In this study, the antioxidant, anti-xanthine oxidase, anti-melanogenic and anti-wrinkle effects of methanol (ME) and hot water (HE) extracts from the fruiting bodies of Phellinus vaninii were investigated. The 1,1-diphenyl-2-picryl-hydrazyl free radical scavenging activity of 2.0 mg/mL HE (95.38%) was comparable to that of butylated hydroxytoluene (96.97%), the reference standard. The hydroxyl radical scavenging activities of ME (98.19%) and HE (97.55%) were higher than that of butylated hydroxytoluene (92.66%) at 2.0 mg/mL. Neither ME nor HE was cytotoxic to murine melanoma B16-F10 cells at 25-750 ㎍/mL. Although the xanthine oxidase (XO) inhibitory effects of ME and HE were significantly lower than that of allopurinol, the values were higher than 84 percent. The in vitro tyrosinase inhibitory activities of ME and HE were comparable to kojic acid at 2.0 mg/mL. The cellular tyrosinase and melanin synthetic activities of ME and HE on B16-F10 melanoma cells at 500 ㎍/mL were higher than arbutin, indicating that the inhibitory effects of arbutin on the tyrosinase and melanin synthesis were higher than those of ME and HE. The collagenase inhibitory activity of HE was comparable to EGCG at 2.0 mg/mL, however, the elastase inhibitory activity of ME and HE was lower than EGCG at the concentration tested. The study results demonstrated that the fruiting bodies of Ph. vaninii possessed good antioxidant, anti-xanthine oxidase, cell-free anti-tyrosinase, cellular anti-tyrosinase, anti-collagenase, and moderate anti-elastase activities, which might be used for the development of novel anti-gout, skin-whitening, and skin anti-wrinkle agents.
