In this study, we tried to verify the value of the use of Mucuna pruriens (M. pruriens) extract as an antioxidant functional cosmetic material based on natural materials. After extracting, concentrating, and freeze-drying M. pruriens with water, 70% ethanol, and 70% acetone as solvents, samples of powdered hydrothermal extract (MW), 70% ethanol extract (ME), and 70% acetone extract (MA) were prepared. As a result of analyzing antioxidant activity through DPPH radical scavenging activity, ABTS⁺ radical scavenging activity, SOD-like activity, reduction ability, total phenol and flavonoid content analysis using MW, ME, and MA, all showed excellent antioxidant effects. Therefore, it is believed that M. pruriens extract is highly likely to be used as a natural material for antioxidant-related functional cosmetics.

The Rosa multiflora, a well-known plant belonging to Rosacea, is widely used in orthodox medicine in worldwide. However, its biological activity as a functional ingredient for cosmetic products have not yet been studied. Accordingly, an investigation of the above mentioned atrributes was performed on a 50% ethanol extract of Rosa multiflora. The antioxidant activities were determined by DPPH. Additionally, the contents of total phenols and flavonoids were analyzed. Also, the phenolic compounds were detected using HPLC. The melanogenesis regulatory effect was evaluated using melanin content and cellular tyrosinase activity in B16F10 melanoma cells. The elastase inhibitory activity assay was performed for anti-wrinkle effect. The antimicrobial activity was assessed using the disc diffusion assay. The DPPH radical scavenging ability, denoted by the $SC_{50}$ value was found to be $123.1{\mu}g/ml$, whereas that of positive control (ascorbic acid) was $27.5{\mu}g/mL$. The content of total polyphenol and flavonoid content were 202 mg/g and 86.77 mg/g, respectively. In addition, astragalin and gallic acid were identified in the extract. Also, the ethanol extract significantly inhibited ${\alpha}$-MSH-induced melanogenesis in B16F10 cells. For anti-wrinkle effect, elastase inhibition activity of the ethanol extract was 53.2% at a concentration of $100{\mu}g/ml$. The antimicrobial activity of the extract against S. aureus and E. coli was observed to be 0.5 - 5%, and no significant activity was noted against C. albicans. Therefore, the ethanol extract of Rosa multiflora can be used effectively for development of functional cosmetic materials.

This study confirmed emulsion stability after performing antioxidant, whitening, antibacterial, and anti-inflammatory efficacy evaluation to find out the availability of Sicyos angulatus L. (SA) which is designated as an ecological disturbance species as a functional cosmetic material. SA was extracted with Deionized Water (SAW) and 70% EtOH (SAE). Compared to SAW, SAE has excellent antioxidant efficacy by showing scavenging activity and SOD-like activity against DPPH radical and ABTS⁺ radical, and inhibits melanin production by inhibiting the activity of tyrosinase. SAW had no antibacterial effect on Escherichia coli (E.c), Staphylococcus epidermidis (S.e), Staphylococcus aureus (S.a), Pseudomonas aeruginosa (P.a), and Cutibacterium acnes (C.a) strains, while SAE showed antibacterial activity by producing clear zones in E.c, S.e, P.a, and C.a strains except S.a. In LPS-treated RAW 264.7 cells, SAE showed efficacy against anti-inflammatory by inhibiting the production of NO by inhibiting the expression of iNOS and COX-2 than SAW. It was confirmed that the SAE-added emulsion was not separated at temperatures of 4℃, 25℃, and 50℃, the pH and viscosity did not change significantly in numerical terms, and the particle size was similar to that of the control emulsion, so it did not affect the formulation. Based on these results, we suggest its potential as a new material for functional cosmetics research.

Red pepper (Capsicum annuum L.) is one of the most consumed vegetable worldwide. In this study, we tried to suggest the possibility of Cheongyang pepper as a functional cosmetic material by identifying the physiological activity, especially antioxidant and whitening effects of Cheongyang pepper through bibliometric analysis and experimental studies. A bibliometric analysis was performed through co-word analysis of 8,892 papers retrieved from SCOPUS. 4 research fields were obtained by cluster mapping from VOSviewer software, among which we noted the antioxidant activity of extracts from Capsicum annum L.. Phenol as a useful ingredient of Cheongyang pepper was analyzed using HPLC (high-performance liquid chromatography). Antioxidant and whitening effects were evaluated by measuring DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity, hydrogen peroxide scavenging activity, and tyrosinase inhibitory activity. Cheongyang pepper extract showed contents of 0.106 ± 0.01 and 0.105 ± 0.02 mg/g, respectively, in the order of gallic acid and protocatechuic acid. The extract exhibited 56.95% DPPH scavenging activity and 43.97% hydrogen peroxide scavenging activity at a concentration of 1,000 ㎍/ml. In addition, 1,000 ㎍/ml of the extract inhibited tyrosinase activity by 52.44% and 42.61%, respectively in a whitening efficacy test using L-tyrosine and L-DOPA (L-3,4- dihydroxyphenylalanine) as substrates. These results suggest that Cheongyang pepper extract and its active ingredients have antioxidant and whitening effects, and the possibility of future development as a whitening functional cosmetic material.
