Angelica gigas Nakai (AGN) is a perennial plant belonging to the family Apiaceae. Its root has been utilized as a traditional medicine especially in Korea. This study was carried out to evaluate the potential use of extracts from AGN root parts as a cosmetic material. The dried AGN roots are divided into body (B), thick root (TkR), medium root(MR) and thin root (TnR) according to their diameter before cutting into medicine. B, TkR and MR of AGN are combined and used as medicinal herbs (MH). The extracts from AGN each root part (B, TkR, MR, TnR, MH) were used to test the effect on cell viability using MTS assay and to examine inhibitory effect on melanin accumulation in B16F10 melanoma cells. All extracts (50 - 200 ㎍/mL) from the each root part did not affect the cell viability. And inhibitory effect of all root extracts (200 ㎍/mL) on melanin accumulation was 12-19%. Especially, TnR showed similar inhibitory effect on melanin accumulation to MH. In addition, DPPH and ABTS free radical scavenging activity were higher in the TnR extract compared to MH. This study showed that the TnR extract exhibit high inhibitory effect on melanin accumulation and antioxidant activity compared to MH, suggesting that TnR extract has potential as a cosmetic ingredient.

The purpose of this study was to investigate the biological activities of an aqueous extract of Angelica gigas (Ag) fermented by Saccharomyces cerevisiae (Sc). First, the soluble solids of the F/3 group, in which the Ag was fermented by Sc for 3 days, decreased from $1^{\circ}Bx$ to $0.9^{\circ}Bx$. On the other hand, the pH increased with the number of days of fermentation. The result of a TLC experiment confirmed that it gradually decomposed into a low-molecular weight sugar form upon fermentation. The total phenolic compounds and flavonoid contents were higher in the fermented group than in the non-fermented group. K and Ca contents were increased by fermentation in the following order: F/3, NF, and F/0 groups. Decursin and decursinol angelate contents were highest in the F/3 group. The DPPH (${\alpha}$, ${\alpha}{\prime}$-diphenyl-${\beta}$-picrylhydrazyl) radical scavenging activity of the NF, F/0, and F/3 groups were 41.89%, 39.51%, and 60.26%, respectively. The inhibition activities of tyrosinase and lipoxygenase were stronger in the F/3 group than in the NF group. This experiment showed that the fermentation of Ag Nakai can lead to an increase in its antioxidant ability, physiological activity, whitening and anti-inflammatory effects. Thus, this oriental herbal medicine can be developed into a functional material that can be utilized in the development of cosmetic products in future.

This study was conducted to develop functional sources of herbal cosmetics for treatment of skin aging and inflammatory disorders using volatile flavor extracts of four different herbal medicinal prescriptions including Cnidium officinale Makino (COM), Angelica gigas Nakai (AGN), Mentha arvense L. (MAL), Artemisiae argyi Folium (AAF), Paeonia lactiflora Pall (PLP), Rehmanniae Radix Preparata (RRP), Scutellaria baicalensis Georgi (SBG), Panax ginseng C.A. Meyer (PGM), Glycyrrhiza uralensis Fisch (GUF). The volatile flavor extracts of four different herbal medicinal prescriptions (HH-1: COM, AGN, PLP, RRP, HH-2: COM, AGN, PLP, RRP, SBG, PGM, GUF, HH-3: COM, AGN, MAL, AAF, HH-4: COM, AGN, MAL, AAF, SBG, PGM, GUF) were extracted using SDE and their antioxidant and anti-inflammatory effects were measured by using DPPH radical and SLO, respectively. As a result, HH-2 showed moderate DPPH radical scavenging activity (68.24 %) and the strongest SLO inhibitory activity (83.96 %) at 100 ${\mu}g$/mL. Moreover, HH-2 of four different prescriptions significantly inhibited NO production on LPS-stimulated RAW 264.7 cells in a dose-dependent manner without considerable cell cytotoxicity at range of 2.0 ~ 50 ${\mu}g$/mL. Additionally, HH-2 also effectively suppressed the production of $PGE_2$ and IL-6, which are responsible for promoting the inflammatory process. Major volatile components of HH-2 were identified as eugenol, paeonol, butyl phthalide, ${\beta}$-eudesmol and butylidene dihydrophthalide by GC-MS analysis. Thus, these results suggest that HH-2 may be useful as a potential source of anti-inflammatory agents in herbal medicinal cosmetics.

For standardization of LMK02 quality, Ginsenoside Rg3 of Red Ginseng and Decursin of Angelica gigas Nakai in the constituents of LMK02 were estimated as indicative components. From LMK02 water extract, has been used in vitro test for its beneficial effects on neuronal survival and neuroprotective functions, particularly in connection with APP-related dementias and Alzheimer's disease (AD). $A{\beta}$ oligomer derived from proteolytic processing of the ${\beta}$-amyloid precursor protein (APP), including the amyloid-${\beta}$ peptide ($A{\beta}$), play a critical role in the pathogenesis of Alzheimer's dementia. We determined that oligomer amyloid-${\beta}$ ($A{\beta}$) have a profound attenuation in the increase in rat hippocampus H19-7 cells from. Experimental evidence indicates that LMK02 protects against neuronal damage from cells, but its cellular and molecular mechanisms remain unknown. Using a hippocampus cell line on $A{\beta}$ oligomer-induced neuronal cytotoxicity, we demonstrated that LMK02 inhibits formation of $A{\beta}$ oligomer, which are the behavior, and possibly causative, feature of AD. In the Red Ginseng, the average amounts of Ginsenoside Rg3 were $47.04{\mu}g/g$ and $42.3{\mu}g/g$, 90 % of its weight were set as a standard value. And, in the Angelica gigas Nakai, the average amounts of Decursin were 2.71 mg/g and 2.44mg/g, 90 % of its weight were also set as a standard value. The attenuated $A{\beta}$ oligomer in the presence of LMK02 was observed in the conditioned medium of this $A{\beta}$ oligomer-induced cells under in vitro. In the cells, LMK02 significantly activated antiapoptosis and decreased the production of ROS. These results suggest that neuronal damage in AD might be due to two factors: a direct $A{\beta}$ oligomer toxicity and multiple cellular and molecular neuroprotective mechanisms, including attenuation of apoptosis and direct inhibition of $A{\beta}$ oligomer, underlie the neuroprotective effects of LMK02 treatment.

We tried to analyze the inflammation reactions by treatment of AG, AS and AA in murine RAW 264.7 cells. To investigate the effect of AG, AS and AA on cell viability of RAW 264.7 cells, AG, AS and AA were treated for 24 h and MTS assay was performed. Cell viabilities were increased in $1,600{\mu}g/ml$ concentration by AS, AA and AG treatments, respectively. The mRNA expression levels of $IL-1{\beta}$, $TNF-{\alpha}$ and iNOS were increased by AG and AA treatment at a concentration of $200{\mu}g/ml$ in RAW 264.7 cells without Lipopolysaccharide (LPS) treatment. The mRNA expression levels of $IL-1{\beta}$, $TNF-{\alpha}$ and iNOS were increased by AG and AA 6 h treatment at a concentration of $200{\mu}g/ml$ with LPS treatment. In this study, we observed that AG, AS and AA show various activities on inflammation reaction depend on their treatment time. In the future, studies should be conducted to investigate the effects of AG, AS and AA on the various inflammatory responses of macrophages.

According to the statistical data, stroke is about 13.9% of leading causes of death. Some herbal medicines including Paeonia lactiflora, Angelica gigas nakai and Prunus persica, etc., had been reported to be effective in preventing stroke and mBHT (Modified BoyangHwanoTang) was an advanced prescription used in Korean clinics. Orally disintegrating tablets (ODT) is useful for patients suffering from dysphagia, motion sickness, repeated emesis and mental disorders. Further, drugs exhibiting satisfactory absorption through the mucosa intended for immediate pharmacological action could be advantageously formulated in ODT. The aim of this study was to develop the most efficient ODT formulation of mBHT. Corresponding herbal medicines comprising mBHT were extracted with water for 3 hr at 95~$100{^{\circ}C}$ and then dried. mBHT extract was obtained with about 30% of yield. Subsequently, some pharmaceutical excipients such as spray-dried lactose, crospovidone, glyceryl behenate and/or cogrinded-treated arabia gum were used to achieve an immediate disintegration of mBHT ODT in oral cavity. The requirements of ODT with mechanical strength sufficient to stand the rigors of handling and capability of disintegrating within a few seconds in contact with saliva are indispensable. mBHT ODT prepared by the wet granulation method showed a disintegration time of below 30 sec.

Diabetes has been one of major health risks in industrialized countries. AMP-activated protein kinase (AMPK) has been focused as a novel therapeutic target for the treatment of metabolic syndromes, because AMPK increases glucose uptake through independent insulin signal pathway. In this study, we investigated the anti-diabetic effect of Angelica gigas Nakai extract (AGNEX), a mixture of decursin and decursinol angelate (53 : 47), decursin and decursinol angelate on blood glucose, glucose transport (GLUT) and AMPK expression levels in streptozotocin (STZ)-induced diabetic rats. To induce diabetes, 50 mg/kg of STZ was injected via i.v. route and AGNEX 2 mg/kg (STZ+AG), decursin 2 mg/kg (STZ+D), decursinol angelate 2 mg/kg (STZ+DA), and metformin 100 mg/kg (STZ+M) were administered orally for 21 days. STZ+DA group showed a significant decrease in fasting blood glucose levels compared to the other groups. Decursinol angelate significantly upregulated expression of glucose transporter 4 (GLUT4) and phosphorylation of AMPK (p-AMPK) in skeletal muscle of rats. In pancreas of rats, decursinol angelate significantly increased expression of GLUT2 through down-regulation of p-AMPK. In addition to the result of pancreatic islets morphology, AGNEX, decursin, decursinol angelate, and metformin treated group recovered ${\beta}$-cell damage by hyperglycemia. These results indicate that decursinol angelate might be a potential anti-diabetic agent and AGNEX could be useful in the treatment of diabetes mellitus.

This study was performed to examine immuno-regulatory activities of Ehpedrae Sinica STAPF, Rubus Coreanus Miq. and Angelica gigas Nakai extracts in conbination with ultrasonification. The extract yields of plants were the highest in the extraction system of $60^{\circ}C$ and 40 kHz of ultrasonification. The immune cell growth ratio of human immune B and T cells was increased compared to other fractions by the water fraction of the plants at $60^{\circ}C$ and 40 kHz. The water fractions of the plants at $60^{\circ}C$ and 40 kHz increased the specific secretion of IL-6 and $TNF-{\alpha}$ of human immune B and T cells compared to other fractions of the plants. The water fraction of Ehpedrae Sinica STAPF among the plants was observed to show the highest specific secretion of IL-6 and $TNF-{\alpha}$. Also, NK-92 MI cells growth was increased in adding the water fractions of the plants at $60^{\circ}C$ and 40 kHz. The water fraction of Ehpedrae Sinica STAPF among the plants showed the highest in NK-92 MI cell growth ratio. The differentiation activity of the HL-60 cells significantly increased in adding the water fraction of Ehpedrae Sinica STAPF compared to other fractions of the plants. These results suggest that the water fractions of the plants in extraction system of temperature $60^{\circ}C$ and ultrasonification 40 kHz have marked useful immuno-stimulatory activities.
