  • Medicinal plants resources are becoming important assets since their usages have been expanded to the development of functional foods for human health, natural cosmetics, and pharmaceutical industries. However, names are different from each country and their phylogenetic origins are not clear. These lead consumers to be confused. In particular, when they are morphologically similar and distributed as dried roots, it is extremely difficult to differentiate their origins even by specialists. Recently, molecular markers have been extensively applied to identify the origin of many crops. In this review, we tried to overview the current research achievements for the development of suitable 'origin identification' regarding to the differentiation of Angelica species. Furthermore, more advanced techniques including amplification genome based marker analyses are also discussed for their practical applications in the authentication of particular medicinal plant in Angelica species.

  • Monoterpenoids were recently found as main biologically active compounds which is responsible for various physiological effect in goat's beard (Aruncus dioicus). Ethyl acetate extract of A. dioicus (ADE) was treated to B16F10 melanoma cells for the examination of whitening activity. MTT assay was performed to evaluate cell toxicity and the result showed that slight cell toxicity (> 10%) by over $500{\mu}g{\cdot}mL^{-1}$. Thus, 0, 5, 10, or $50{\mu}g{\cdot}mL^{-1}$ ADE was used for further experiments. We found that tyrosinase activity was decreased according to ADE concentration, and the total melanin content was also dramatically reduced. Especially with $50{\mu}g{\cdot}mL^{-1}$ ADE treatment tyrosinase activity was reduced to 35.6%, and 58.8% of melanin content was lowered. In addition, whitening related proteins including tyrosinase, tyrosinase related protein 1 (TRP1), TRP2, microphthalmia associated transcription factor (MITF) and cAMP and protein kinase A (PKA) were reduced by ADE treatment. It caused decreased phosphorylation of cAMP response binding protein (CREB) but increased phosphorylation of extracellular signal related kinase (ERK). Therefore, in this paper we would like to suggest the potent usage of A. dioicus natively grown in Ulleungdo, Korea as materials of functional cosmetics by confirming whitening activity related with melanin content.

  • This study analyzed convergence status among input technologies used in technology development with Technology I-O analysis. It was another version of industry input-output analysis which is used in technology planning. This case is an analysis of association between technology an product. The subjects of analysis were 401 tasks that applied to '2012 Convergence Technology Development Project for Small and Medium Businesses' promoted by Korea Technology & Information Promotion Agency for Small and Medium Enterprises. The process of analysis is as followed. First step, we made a matrix table as an input of technology input-output analysis. Input was defined by technology and output was defined by the product. Input technology was defined in a 3-digit code under National Science Technology Classification and output products were defined in a 5-digit under National Standard Industry Code. Second, the Spillover ratio among technologies were calculated and was used to make a picture of technology linkage. As a result of analysis, technology spillover of embedded S/W was the highest in IT convergence, mold product in ET convergence, and functional cosmetics development technology in BT convergence. In general, IT convergence had many element technologies with high technology spillover, and ET had a small number of element technologies with high technology spillover. Therefore, investment effect of element technology is expected to be large if investment on element technologies with high technology spillover is important for vitalizing convergence.

  • This study was conducted to examine the changes in the molecular structure and physiological activities of silk fibroin by gamma irradiation. The results of gel permeation chromatography and sodium dodecyl sulfate-polyacrylamide gel electrophoresis showed that the molecular weight of fibroin was increased depending upon the irradiation dose. Secondary structure of fibroin determined by using circular dichroism revealed that the ratio of $\alpha$-helix was increased up to 10 kGy and then decreased depending upon the irradiation dose. Whereas, the ratio of $\beta$-sheet, $\beta$-turn, and random coil were decreased and then increased with an alteration in the $\alpha$-helix secondary conformation. The 2.2-diphenyl-1-picryl-hydrazil (DPPH) radical scavenging activity of fibroin was increased by gamma irradiation at 5 kGy, but was decreased above 10 kGy depending upon the irradiation dose. Also, the inhibition activities of tyrosinase and melanin synthesis of fibroin were increased by gamma irradiation. These results indicated that gamma irradiation could be used as an efficient method to make fibroin more suitable for the development of functional foods and cosmetics.

  • Luffa cylindrica Roem (sponge gourd) belongs to the Cucurbitaceae family and has been cultivated as an ornamental plant in Korea. Recently, its cultivation area has been increased with an increase in demand for it as an ingredient in cosmetics, herbal medicines, and health supplements. We analyzed inorganic components of sap collected from land race sponge gourds. We also measured antioxidant enzyme activities and antimicrobial activities of the plant, seed, and sap to examine functional properties of sponge gourd. The sap of the sponge gourd contained high levels of K, Ca, P, and Mg, with the most abundant mineral in the sap being K ($470mg{\cdot}L^{-1}$). The amounts of Ca and Mg were 2 and 1.7 times more than those found in cucumber (Cucumis sativus), respectively. Ascorbate peroxidase was more active than catalase and superoxide dismutase in various plant parts of sponge gourd. Antioxidant activities were much lower in stems than in other plant parts such as leaves, roots, flowers, fruits, seeds, and sap. In addition, sap showed a very low level of antimicrobial activity against two food-borne pathogens, Vibrio parahaemdyticus and Propionibacterium acne, and none against the other eight tested food-borne pathogens. Antimicrobial activities against Candida albicans and Malassezia furfur, which causes dermatitis, appeared to be higher in sap than in other parts of sponge gourd plants. Overall, the antimicrobial activity against Malassezia furfur appeared to be higher than against Candida albicans.

  • Abeliophyllum distichum Nakai is deciduous shrubs of flowering plant in Oleaceae. It is important plant resources and consists of one species in the world. Also the endemic plant of A. distichum has been protected and designed endangered plant in Korea. For this reason, study on the immature seeds of A. distichum (ADS) hasn't progressed. In the present study, we evaluated the antioxidant activity and inhibitory effects on proteins and mRNA levels were related in the whitening effect in B16F10 cells. ADS was effective for reaction oxygen species (ROS). ROS causes various diseases such as aging, inflammation, cancer, and etc. Antioxidant properties were evaluated DPPH, ABTS radical scavenging activity and Reducing power. Plants were known that contained phenolic compounds were related in antioxidant activity. Phenolic compounds were phytochemicals commonly named natural polyphenols. These are secondary metabolites of plants involved in the defense against different types of stresses. In results, ADS suppressed the expression and transcription of Tyrosinase, TRP-1, TRP-2, and Microphthalmia-associated transcription factor (MITF). Tyrosinase, tyrosinase-related protein 1 (TRP-1), tyrosinase-related protein 1 (TRP-2) are known to play an important role in melanin biosynthesis. MITF regulated the expression and transcription of Tyrosinase, TRP-1, and TRP-2. In conclusion, ADS was effective in both antioxidant activities and whitening effects. Also, they were associated with the content of phenolic compounds. We suggested that ADS can be use antioxidants and skin-whitening functional cosmetics material derived from natural plant resources.

  • Hair graying is processed by loss of melanin production caused by the decrease of activity and number of melanocyte and the accumulation of hydrogen peroxide ($H_2O_2$) in the hair follicle with increase of age. The purpose of this study was to investigate the effect the Black oryzasativa ethanolic extract (BLEE) on the melanin production. In this study BLEE at $8{\mu}g/ml$ or more showed a significant 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity and reduction power. BLEE at $16{\mu}g/ml$ or more showed promoted tyrosinase activity and melanin production. In addition BLEE scavenged intracellular $H_2O_2$ in 2',7'-dichlorodihydrofluorescein (DCF) fluorescence assay in B16F1 cells. However, Western blot analyses displayed that BLEE decreased the expression level of catalase, but no effect on the expression level of tyrosinase, tyrosinase associated protein-1 (TRP-1), tyrosinase associated protein-2 (TRP-2) and microphthalmia-associated transcription factor (MITF) transcription factor involved in melanogenesis. Thus, the promotive effect of BLEE on melanin production is attributed to the increase of tyrosinase activity and the reduction of intracellular $H_2O_2$ level. In conclusion, BLEE played a key role in in promoting melanin production, which suggests that the BLEE could be applied as a potential functional material in the development of hair care cosmetics related to the promotion of melanin production for the growth of black hair.

  • Glycolic acid, an alpha-hydroxy acid derived from fruit and milk sugars, has been commonly used as a cosmetic ingredient since it was known to have photo-protective, anti-inflammatory effects, and anti-oxidant effect in UV-irradiated skin. However, little has been know about the functional role of glycolic acid on UV-induced skin cell proliferation. It was previously found that glycolic acid inhibited UV-induced skin tumor development in hairless mouse. As a possible mechanism of glycolic acid on the UV-induced skin tumor development, the ability of glycolic acid to inhibit the UVB-induced cell growth and possible mechanisms were investigated. Glycolic acid treatment attenuated the UV-induced cell proliferation and apoptotic cell death in the skin. In vitro study, glycolic acid inhibited the UVB-induced cell growth and apoptotic death through inhibiting caspase-3 activity. These results suggest that glycolic acid may exert the Inhibitory effect on the UVB-induced skin tumor development by regulating cell growth and apoptotic cell death.
