This study assessed the whitening and anti-aging effects of the Cistanche deserticola extract, to develop a cosmetic substance. The cell viability of the Cistanche deserticola extract was evaluated in B16F10 melanoma cells by the MTT (3-(4,5-dimethylthaiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay. The cell viability of the extract was determined to be 90% at 4mg/ml concentration. Furthermore, the tyrosinase, collagenase, and elastase mRNA expression level were measured by RT-PCR, using the Cistanche deserticola extract treated B16F10 melanoma cells. At 4 mg/ml concentration, mRNA expression level of tyrosinase, collagenase, and elastase was dramatically decreased to 80.9%, 37.6%, and 70.9%, respectively. The antioxidant activity of the Cistanche deserticola extract was determined by DPPH free radical scavenging. The DPPH free radical scavenging capacities ranged from 70.6% to 82.6%, when evaluated from 2 mg/ml to 10mg/ml concentrations. The effects of whitening and anti-aging of the Cistanche deserticola extracts were examined at 2, 4, 6, 8, and 10 mg/ml concentration. Tyrosinase activities were inhibited from 66.8% to 78.5%, elastase activities were inhibited from 67.6% to 79.3%, collagenase activities were inhibited from 72.3% to 83.6%, and hyaluronidase activities were inhibited from 65.8% to 69.2%, respectively. These data suggest that the Cistanche deserticola extract is effective in whitening and anti-aging; therefore, it is considered to be a functional cosmetic material in cosmetic products.

Recently, consumer demand for functional cosmetics containing natural ingredients has been greatly expanded. To develop the natural cosmetic materials, we selected 3 plants, Chrysanthemum zawadskii Herbich (CZ), Perilla frutescens (L.) Britton var. acuta Kudo (PF), and Rosa multiflora Thunberg (RM) which showed high total flavonoid contents (TFC), total polyphenol contents (TPC), and strong DPPH radical scavenging effect. We determined astragalin, chlorogenic acid, and rosmarinic acid as a marker compound for quantitative analysis of the content of each material and standardization of the quality standards and manufacturing standards through LC/MS analysis. HPLC-DAD was used to simultaneously analyze these marker components of three natural product complexes (Mix) and to validate the analytical method through experiments such as linearity, accuracy and precision. The detection wavelengths were set at 210, 265, and 330 nm. The detected 3 compounds from extract of CZ, PF, RM showed significant linearity ($R^2${\geq_-}$0.9947). The limit of detection (LOD) of chlorogenic acid, astragalin and rosmarinic acid were $8.29{\mu}g/ml$, $2.28{\mu}g/ml$, and $27.00{\mu}g/ml$, respectively. The limit of quantification (LOQ) of chlorogenic acid, astragalin and rosmarinic acid were $25.11{\mu}g/ml$, $6.92{\mu}g/ml$, and $81.83{\mu}g/ml$, respectively. The contents of the three indicators of Mix were 19.82-24.71 mg/g of chlorogenic acid, 43.80-46.02 mg/g of astragalin, and 46.33-48.57 mg/g of rosmarinic acid.

In this study, we prepared fractions from Cynanchum paniculatum (C. paniculatum) with ethyl acetate and identified the structure and content of paeonol, an indicator substance. Fractions were obtained by sequential solvent fractions using n-hexane, methylene chloride, ethyl acetate, n-butanol, and distilled water, and showed the highest paeonol content in ethyl acetate (EtOAc). The structure of the ethyl acetate fraction (EA) was confirmed by nuclear magnetic resonance (NMR) and the content was determined by high performance liquid chromatography (HPLC) analysis. The antioxidant activity of EA was tested through its ability to scavenge 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS), and its ability to inhibit nitric oxide (NO) production in RAW 264.7 cells induced by lipopolysaccharide (LPS) was tested for its ability to inhibit NO production in a concentration-dependent manner. Furthermore, MMP-1 production induced by ultraviolet B (UVB) was decreased in a concentration-dependent manner by the EA, and the ability to produce procollagen type-I was increased in a concentration-dependent manner. In addition, as a result of conducting clinical trials using cosmetic formulations containing EA, the effect of improving wrinkles around the eyes was confirmed. Thus, it is expected that Cynanchum paniculatum can be used as a natural functional cosmetic material with antioxidant and anti-aging effects.

Consumers have recently preferred to purchase extensive UV intercepting products, which are waterproof and free from side effects on skin. Testing Cytoroxicity in SR method, cell survivial ratio of UV-B interceptors decreased above 0.08W/V%, and so did that of UV-A interceptors above 0.06W/V%. Also, Patch-test of inorganic UV interceptors resulted in no skin irritation even below 10.0 and 11.25. UV interceptors in the sunlight showed yellowish discoloration in 5 to 14 days. In absorption curves, UV-B was most suitable for Octyl methoxycinnamate and UV-A for Butyl methoxy dibenzoylmethane. Fro this reason, Nylonpoly UVA/UVB the material of OMC and BMDM coated with Nylon & polyethylene, was used as the organic UV interceptor. And zinc oxide and titanium dioxide was used as inorganic UV ibterceptors. The appropriate mixture ratio of ZnO and TiO2 was 6 to 4.6% of ZnO, 4% of TiO2 and 5% of Nylonpoly UVA/UVB were all combined with our sunscreen cream. The SPF value of in-vivo applied to a guinea pig was 34.9 and that of in-vivo was 38.5. Cyclomerhicone and dimerthicone were used in water-in-Silicone system. Ceryl diverhicone and sorbitan sesquioleate were used as emulsifiers and MgSO4, 7H2O, Mg-stearate/Mg-Al-stearate copolymer as emulsification stabilizers. In practical application, each SPF duration of O/W type and W/S type containing sunscreen cream of the same content showed that W/S type of sunscreen cream was 5 times as durable as the other. This product is fit for using in swimming, climbing or skiing. This research is to minimize skin trouble used by UV interceptors and to make one with proper softness, skin safety and UV intercepting efficiency.

To use mountain ginseng adventitious roots (MGAR), which is superior in functionality compared to ginseng, and to mass produce raw materials as a functional cosmetic material, the antioxidant and cosmeceutical activities of the extracts of MGAR at different ethanol concentrations (0, 20, 40, 60 and 80%) were compared and analyzed. At first, different ethanol concentrations were compared to determine the best solvent for the extraction of phenolic compounds from MGAR. An 80% ethanol extract with 10.07 mg of gallic acid equivalents/g sample and 0.94 mg of quercetin equivalents/g sample was the best solvent in the extraction of phenolic compounds. However, the 60% ethanol extract had the highest antioxidant activity, evident by 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, Trolox equivalent antioxidant capacity (35.01 mM Trolox/g sample) and ferric reducing antioxidant power (460.94 mM $FeSO_4/g$ sample). However, the inhibitory activities of the 80% ethanol extract from the MGAR against tyrosinase and elastase were higher than those of the other extracts. The results of this study show that the extract of MGAR can be used as an easily accessible source of natural antioxidant and as a possible cosmetic ingredient in the cosmeceutical industry. However, the components responsible for the antioxidant and cosmeceutical activities of the MGAR extracts are currently unclear. Therefore, it is suggested that further studies should be carried out to isolate and identify the antioxidant and cosmeceutical components in MGAR.
