The purpose of this study was to investigate the possible use of the Boehmeria nivea var. nipononivea extract and fractions for the development of natural cosmetic ingredients. The leaves of B. nivea var. nipononivea, extracted by 70% ethanol, were sequentially fractionated with n-hexane, dichloromethane, ethylacetate, and n-butanol. As a result of DPPH and ABTS test, ethyl acetate fractionation was shown to be excellent in radical scavenging activity. For the antimicrobial activities against Staphylococcus aureus, Staphylococcus epidermidis, Cutibacterium acnes and antibiotic resistant strains, MIC and birth control rate were observed by paper disc method. In the antibacterial activity by the disc diffusion assay against S. aureus, S. epidermidis and C. acnes, the dichloromethane and ethylacetate fraction showed stronger antibacterial activity than the other fractions and extract. Moreover, the ethylacetate fraction showed strong nitric oxide (NO) production inhibitory effect in lipopolysaccharide (LPS)-stimulated RAW 264.7 cell. In conclusion, we found that B. nivea var. nipononivea extract was not cytotoxic and showed antioxidant, antimicrobial and anti-inflammatory effects. These results suggest that the Boehmeria nivea var. nipononivea extract and fractions could be applied as an effective cosmetic material with antioxidant activity.

In this study, we investigated the biological functions of Grateloupia elliptica (G. elliptica) fermented with Aureobasidium pullulans (A. pullulans). Total phenolic contents (TPC) of the hot-water extract of the fermented G. elliptica increased 2.7 folds than that of the non-fermented G. elliptica. Furthermore, total flavonoid contents of both the hot-water extract and the ethanol extract increased maximum 2.4 folds amounts than non-fermented G. elliptica extracts.HaCaT cells were induced inflammation treated with LPS (1 ㎍/mL) or H₂O₂ (1mM) and examined with 100 ㎍/mL of G. elliptica extracts. The extraction of the fermented G. elliptica increased HaCaT cell proliferation in the maximum 10% than non-fermented G. elliptica extraction. Furthermore, investigating changes in protein expression associated with inflammation resulted in a significant reduction in the expression of cyclooxygenase-2 and 70 kDa heat shock proetin. Conclusively, the extracts of G. elliptica fermented with A. pullulans have bioactive functions both anti-oxidant to protect environmental stresses and anti-inflammation activity. Hence, G. elliptica fermented with A. pullulans would be a good natural resource as bioactive ingredients for cosmetics. Therefore, G. elliptica fermented with A. pullulans is useful as a astringent material with anti-inflammatory skin.

This study was conducted to analyze the fragrance characteristics of Cymbidium 'Saelbit' and 'Midan' according to floral organs. As test materials, full bloom flowers were divided into four organs: sepal, petal, labellum, and column. Using the gas chromatography (GC) based electronic nose, fragrance patterns, intensity, and volatile components were analyzed. Principle component analysis (PCA) and discriminant factorial analysis (DFA) plots by electronic nose data showed that volatiles of both cultivars have a distinct difference in fragrance patterns according to the floral organs, and the value of fragrance distance and pattern discrimination index (PDI) between samples was significantly high between control and sepals in both cultivars. Among the main fragrance components, several components including nootkatone were detected in both cultivars and all floral organs. However, few components such as decane were found in specific cultivar or floral organs. These results will provide useful information to select suitable materials with desired fragrance and to enhance the utilization of domestic Cymbidium cultivars. In addition, considering the recent negative perception of artificial ingredients and the growing demand for natural materials, continuous researches on scent properties of promising cultivars are required.

Stroke is among the leading causes of death and long-term physical and cognitive disabilities worldwide, affecting an estimated 15 million people annually. The pathophysiological process of stroke is complicated by multiple and coordinated events. The breakdown of the blood-brain barrier (BBB) in people with stroke can significantly contribute to the development of ischemic brain injury. Therefore, BBB disruption is recognized as a hallmark of stroke; thus, it is important to develop novel therapeutic strategies that can protect against BBB dysfunction in ischemic stroke. Traditional medicines are composed of natural products, which represent a promising source of new ingredients for the development of conventional medicines. Indeed, several studies have shown the effectiveness of Korean medicine on stroke, highlighting the value of Korean medicinal treatment for ischemic stroke. This review summarizes the current information and underlying mechanisms regarding the ameliorating effects of the formula, decoction, herbs, and active components of traditional Korean medicine on cerebral ischemia-induced BBB disruption. These traditional medicines were shown to have protective effects on the BBB in many cellular and animal ischemia models of stroke, and experiments in various animal species, such as mice and rats. In addition, they showed brain-protective effects by protecting the BBB through the regulation of tight junction proteins and matrix metalloproteinase-9, reducing edema, neuroinflammation, and neuronal cell death. We hope that this review will help promote further investigation into the neuroprotective effects of traditional Korean medicines and stimulate the performance of clinical trials on Korean herbal medicine-derived drugs in patients with stroke.

This study was done to evaluate the dermatoxicity of zinc sulfate (ZnSO4) and the protective effect of Rubus parvifolius L. (RP) extract on cytotoxicity of ZnSO4, mordant in cultured SK-MEL-3 cells. For this study, it was done an antioxidative effect as DPPH-radical scavenging ability as well as the diminutive ability of total melanin with cell viability. ZnSO4 significantly decreased cell viability in dose-dependently, and it was mid-toxic. The ascorbic acid significantly increased cell viability damaged by ZnSO4-induced cytotoxicity. In the protective effect of RP extract on ZnSO4-induced cytotoxicity, RP extract significantly increased cell viability compared with ZnSO4-treated group, and also it showed both the DPPH-radical scavenging ability and the decrease of total amount of melanin. From these findings, the cytotoxicity of ZnSO4 is correlated with oxidative stress, and also RP extract effectively protected ZnSO4-induced cytotoxicity via antioxidative effect such as DPPH-radical scavenging ability with the whitening effect by the decrement of total amount of melanin. Conclusively, the natural ingredients like RP extract may be a useful agent for the improvement of antioxidative and whitening effects

Recently, many hangover cure products containing natural ingredients have been made available in the market that are effective for alcohol-related liver damage or for improved liver function. However, the cure for of liver damage or medication for improved liver function are different from hangover cure. Therefore, the efficacy hangover cure products needs to be verified. In this study, we investigated and compared the ameliorating effect of four commercially available hangover cure products on acute ethanol-induced hangover in Sprague - Dawley rats. The four samples were labeled as C, M, R, and S. The efficacy of the samples was evaluated based on the serum concentration and area under the curve (AUC) of blood ethanol and acetaldehyde concentrations to quantitatively assess the hangover cure effect. Ethanol administration to the rats significantly raised the serum alcohol and acetaldehyde levels. The Cmax reduction rates of ethanol for the samples C, M, R, and S were 5.9%, 3.1%, 8.4%, and 11.7%, and the AUC were 8.9%, 2.2%, 12.1%, and 19.6%, respectively, whereas the Cmax reduction rates of acetaldehyde were 14.2%, 15.2%, 28.2%, and 35.0%, and the AUC were 21.6%, 7.5%, 22.4%, and 29.9%, respectively. In conclusion, all samples showed a tendency to relieve hangover in the order of S, R, C, and M in terms of the ethanol concentration, but only sample S showed a statistically significant decrease in both Cmax and AUC for ethanol and acetaldehyde. These results suggest that an objective method for verifying the efficacy of hangover cure products is lacking.

Korean Ginseng is a medicinal herb which grows naturally in korea. an ancient country situated in north-eastern Asia. Its medical use was already well known to herb doctors in this region about five thousand years ago since the effectiveness of korean ginseng has been recognized through practical use for a long time. Korean Ginseng has always been regarded as a devine cure. The name "Ginseng" can be found in various medicinal books. many of which were written as early as B.C. 100. In the records of many chinese medical books. dating from the inception of publishing, it was noted that Korean Ginseng was of the highest level of quality. Korean Ginseng originally grew in the mountains of korea. However, this wild Korean Ginseng(js called SANSAM) could not meet the ever-increasing demands. and from the 16th century. it has been cultivated on farms for mass processing and supplying in korea(js called INSAM). It was already recognized in korea a long time ago(B.C. 57 - A.D. 668) that Korean Ginseng possessed the qualities of panacea, tonic and rejuvenator, and had other medicinal properties as well. The effectiveness of Korean Ginseng is widely recognized among south-eastern Asians as well as Chinese. As its effect has been proved scientifically. Korean Ginseng is now becoming the ginseng for all human beings in the world. Korean ginseng is differently called according to processing method. Dried thing is Insam(white ginseng), boiled or steamed is Hongsam(red ginseng). 장뇌삼(long headed ginseng) is artificially grown in the mountain no in field for a long time. So the body is thin and some long. but ingredients are concentrated. Korean wild ginseng(SANSAM) is rare in these days but we developed cosmetic ingredient. The scientific name of Korean Ginseng is Panax Ginseng. It has acknowledge as a natural mysterious cure among the notheastern peoples. because of its broad medicinal application. The origin of the word" Panax" derived from panacea. a Greek word meaning cure-all. According to the classification method of herb medicines in the Chinese medicinal book. "God-Farmer Materia Medica(A.D. 483-496) korean Ginseng was described as the superlative drug: panacea. tonic and rejuvenator. We studied skin immunological effect. collagen synthesis. cell growth and whitening effect of SANSAM extract. IN cosmetics.. SANSAM extract had skin fibroblast cell growth effect. recover damaged skin in the sun and protect fine wrinkle. Also. In hair product.. inhibits hairless, white hair.its hairless, white hair.

This study aimed to examine the safety of HemoHIM, a dietary supplement containing methoxsalen. HemoHIM is a dietary supplement marketed globally, and a competitor to ginseng. It has been reported to contain methoxsalen, a plant extract for treating psoriasis and vitiligo. Methoxsalen is known to cause hepatotoxicity, but most of the cases has been reported from ingestion as a drug, not a food. There are no reports of hepatotoxicity from the consumption derived from natural products such as Angelica gigas, Cnidium officinale, and Paeonia lactiflora, which are the main ingredients in the HemoHIM. However, a recent case of acute hepatitis was reported in Hong-Kong after ingestion of HemoHIM. It is difficult to conclude that hepatitis was caused by HemoHIM, because there was no check of co-occurring medications with a higher risk of hepatotoxicity, no description of the progress, no quantitative comparison of methoxsalen in HemoHIM to it in common foods such as carrots and celery, and no description of the patient's underlying diseases. On the other hand, there was a study that suggest hemoHIM is safe, and that study had adequate number of subjects even though more studies are needed to ensure safety.

Biorenovation is a method for converting materials using the enzyme properties of microorganisms. Natural products converted by that method increase physiological activity or reduce cytotoxicity. In this study, we investigated the anti-inflammatory activity of crypsinus hastatus prothallium (CH) and biorenovated CH prothallium (CHB) using RAW 264.7 cells stimulated with lipopolysaccharide (LPS). CHB inhibited the production of nitric oxide, prostaglandin E₂ and cytokines (interleukin-6, interleukin-1β, tumor necrosis factor-α) compared to CH at a concentration of 50-200 ㎍/mL. In addition, CHB concentration of 200 ㎍/mL inhibited the expression of inducible nitric oxide synthase and cyclooxygenase-2 protein by LPS stimulation to the level of the untreated control group. These results indicate that CHB could be a novel anti-inflammatory agent for cosmetic and pharmaceutical ingredients.It also suggests that the application of biorenovation has potential usefulness in developing anti-inflammatory materials. It also suggests that the application of bio-renovation has potential usefulness in the development of inflammatory material. We applied Biorenovation technology to Distylium racemosum extract (DR) to generate Distylium racemosum biorenovation product (DRB), and investigated the anti-inflammatory properties of DRB in lipopolysaccharide (LPS)-treated RAW264.7 macrophages. We are applying technology to Biorenovation Distylium racemosum extract (DR) Distylium racemosum was to create a biorenovation product (DRB), lipopolysaccharide (LPS) investigated the anti-inflammatory properties of DRB in RAW264.7 macrophages treated for.
