The purpose of this study was to investigate the antioxidant, nitrite scavenging, angiotensin-converting enzyme (ACE), and tyrosinase inhibition activities of ethanol extracts from Hericium erinaceus (HE) cultured in Angelica keiskei (AK) and Angelica keiskei pomace (AKP). Antioxidant activities of the HE, AK, AKP, HE+AK, and HE+AKP extracts were higher than that of control, but lower than those of BHT and Vit C. Tyrosinase inhibition activity was the highest in AKP+HE extract (90%), whereas those of HE, AK, AKP, and AK+HE extracts were about 57, 61, 82, and 78%, respectively. Nitrite scavenging abilities of various samples were above 80% at pH 1.2, and there was no significant difference between the HE, AK, AK+HE, and AKP+HE extracts at pH 3.0, excepting the AKP extract. ACE inhibition activity was the highest in AKP extract (60%), whereas those of HE, AK, AK+HE and AKP+HE extracts were about 42%, 50%, 35% and 40%, respectively. These results suggest that H. erinaceus cultured in AK and AKP may be used as a raw material for functional foods, and food additives, as well as in the cosmetic industry as a natural source of bioactive compound after further investigation in vivo.

This study was carried out to examine the germanium contents of Angelica keiskei Koidz. and A. acutiloba Kitagawa and to intend to increase its contents while those leaf explants were culturing on MS medium supplemented with organic and inorganic germanium. Ge content of Agelica keiskei Koidz. was 2.1 times higher than that of A. acutiloba Kitagawa. Digestion was done quickly at high temperature, but Ge content was decreased. Callus formation of A. acutiloba Kitagawa was better than that of A. keiskei Koidz. Callus formation of both plants was good in order of pH 5.7, pH 5.4, and pH 6.0. But shoots from callus were formed frequently in A. keiskei Koidz., especially at pH 5.7. Callus formation of both plants was good up to 5 ppm of inorganic ($germanium(GeO_2),$ retarded at 10 ppm, and rarely formed at 100 ppm, but was good up to 10ppm of organic germanium retarded at 50 ppm and formed some-what even at 100 ppm.

Excessive alcohol consumption can cause hangover symptoms, such as headache, drowsiness, dizziness, gastrointestinal distress, and anxiety. The aim of this study was to investigate alcohol metabolizing enzyme activities and antioxidant activities of fruit-vegetable juices containing Angelica keiskei prepared using a low speed masticating juicer in vitro. The acceleration rate of alcohol dehydrogenase (ADH) by A. keiskei-cherry tomato juice (ACJ) and A. keiskei-green grape juice (AGJ) were $163.8{\pm}4.3%$ and $148.2{\pm}6.9%$, respectively. The acceleration rate of aldehyde dehydrogenase (ALDH) by ACJ and AGJ were $185.6{\pm}9.5%$ and $161.1{\pm}4.8%$, respectively. Total polyphenol of ACJ and AGJ were $111.1{\pm}1.6mg/dL$ and $100.8{\pm}2.9mg/dL$, respectively. DPPH radical scavenging activities of ACJ and AGJ were $62.0{\pm}0.5%$ and $61.3{\pm}0.4%$, respectively. Thus, these results indicate that alcohol degrading enzyme activities can be enhanced by fruitvegetable juices containing A. keiskei.

The purpose of this study was to evaluate the anti-atopic-dermatitis effect of Angelica keiskei extract using a DNFB-induced animal model of atopic-dermatitis symptoms. A. keiskei was prepared via extraction with DW, 50% ethanol, and 100% ethanol in addition to fresh juice. All the extracts reduced the thickness levels of the ears and ear epidermis against swelling by DNFB inducement, especially in the aqueous-extract-treated group. The mRNA expressions of matrix metalloproteinases (MMPs), however, were not observed, which may indicate that Angelica keiskei extract alleviates the atopic-dermatitis symptoms in an MMP-independent manner. Finally, the level of the inflammatory cytokine IL-4 was inhibited only in the juice-treated group, although the IL-13 level was inhibited in the juice-, 50%-ethanol-extract-, and 100%-ethanol-extract-treated groups in a dose-dependent manner, and was not inhibited in the aqueous-extract-treated group. Taken together, these results suggest that Angelica keiskei extract has an inhibitory effect on atopic dermatitis, and may be a useful biomaterial for the development of cosmeceuticals.

The anti-cancer effects of Angelica keiskei ethanol extract were evaluated in human breast cancer MDA-MB-231 cells. The concentrations of extract were 1, 2, 3, 4 and 5 mg/mL. Dose-dependent reductions in the number of cells with altered cell shape and pyknotic nuclei were observed at 48 h after treatments. MTT assay also exhibited a similar dose-dependent reduction in mitochondrial reductase activity (p<0.05), in particular, with a rapid reduction in the activity of the 5 mg/mL group. Analysis of cell death with propidium iodide (PI) staining revealed only a slight increase in cell death in the 5 mg/mL group. Analysis of bromodeoxyuridine (BrdU) incorporations also showed a dose-dependent reduction in cell proliferation (p<0.05). Finally, increases in total radical oxygen species (ROS) accumulation in cells, as revealed by DCF-DA staining, were observed in the treated groups in a similar dose-dependent fashion (p<0.05). These results indicate that Angelica keiskei ethanol extract exhibiting anti-cancer effects in MDA-MB-231 cells causes multiple changes in cell shape, enzyme activity, and ROS accumulation, thereby inducing cell death.

To utilize the abandoning byproducts after manufacturing fresh vegetable juice, Hericium erinaceum (H. erinaceum) was cultured using Angelica keiskei (AK) and the byproducts of Angelica keiskei (BAK) as anutrient and the chemical composition of the culture extract was analyzed. When H. erinaceum was cultured using culture media of AK and BAK, it showed 107{\sim}112 mm of growth during 40 days. The moisture contents of AK and BAK extracts were 94.36 and 97.36%, respectively; however, those of extracts of H. erinaceum cultured in AK and BAK decreased to 90.95 and 94.20%, respectively. Reversely, other chemical compositions were increased. The vitamin A content of AK extract was 20.78 IU/100 mL and was higher than those of other extracts. However, vitamin A was not detected in extracts of H. erinaceum cultured with AK and BAK. In contrast, vitamin $B_2$ and C in the extracts of H. erinaceum cultured were higher than those of AK and BAK. Total ash content including Fe, P, Mg, and Ca increased in the extracts of H. erinaceum cultured when compared with AK and BAK extracts. Total amino acid content was also higher in the extracts of H. erinaceum cultured (231.08 and 372.25 mg%) than those in the extracts of AK (177.17 mg%) and BAK (149.99 mg%).

In order to investigate the potential of a Angelica keiskei Koidzumi extract and its fractions as an active ingredient for whitening cosmetics, we prepared Angelica keiskei Koidzumi extract(70% ethanol), and the aqueous suspension was successively extracted with hexane, ethyl acetate(EA), and n-butanol fraction. We measured their inhibitory effects on mushroom tyrosinase and melanin synthesis in B16 melanoma cells and normal human kerationocytes in vitro. They did not show inhibitory activity against mushroom tyrosinase and the melanin synthesis except hexane and EA fractions. Hexane and EA fractions markedly inhibited cellular tyrosinase activity at a lower concentration(25 and 5 ${\mu}g/mL$, respectively) than arbutin(250 ${\mu}g/mL$). We also quantified the released amount of endothelin-1(ET-1), a mitogen of melanocyte, and interleukin-$1{\alpha}$(IL-$1{\alpha})$, a mediator of UVB-induced inflammation. Hexane and EA fractions did not affect IL-$1{\alpha}$ production, but they decreased UVB-induced ET-1 production in normal human keratinocytes in a dose dependant manner. As a result, hexane and EA fractions could inhibit the melanogenesis through the inhibition of UVB-induced ET-1 production in normal human keratinocytes. This result suggests that hexane and EA fractions of Angelica keiskei Koidzumi extract could be used as an active ingredient for cosmetics.

Angelica keiskei is a perennial herb belonging to the Umbelliferae family. In this study, the whitening effect of A. keiskei extracts was examined through melanogenesis and tyrosinase inhibitory assays. The ethanol extract (50%) significantly inhibited tyrosinase in a concentration-dependent manner. RT-PCR revealed that the extract exhibited decreased expression of tyrosinase, tyrosinase-related protein-1, tyrosinase-related protein-2, and melanocyte-inducing transcription factor. These results suggest that the extract can be used as an ingredient for the development of cosmeceuticals.
