Angelica acutiloba is one of the most intensively cultivated medicinal plants in Korea. The roots of this plant have been used as an important herbal drug, especially for the treatment of various female disorders, as the traditional therapy in Korea and other Asian countries. Consumption of its fresh leaves as a healthy vegetable has recently increased. In this study, essential oil fractions were extracted from the roots and leaves of this plant by steam distillation. Compositions of the two oils were compared by gas chromatography-mass spectrometry (GC-MS). The antibacterial activities of the essential oil were determined against three strains of Escherichia coli. DPPH radical scavenging and reducing power tests were performed to evaluateits antioxidant activities. The cytotoxic activities of the essential oil against a human breast and a uterine cancer cell line were estimated by MTT tests. Additionally, the morphological changes after treatment of the oil fraction were observed under a microscope. The essential oil fraction and its main components, Z-ligustilide and butylidene phthalide, inhibited the growth of three E. coli strains examined, with minimum inhibiting concentrations (MICs) ranging from 1.0 mg/ml to 8.0 mg/ml. Additionally, the essential oil fraction of A. acutiloba exhibited significant DPPH free radical scavenging activity and reducing power. Significant cytotoxic activities of the A. acutiloba essential oil were observed for human uterine (Hela) and breast (MCF-7) cancer cell lines.

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.

The effects of volatile flavor extracts of eight different herbal medicines, Juniperus rigida (JR), Saussurea lappa SL), Cnidium officinale (CO), Angelica gigas (AG), Eugenia caryophyllata (EC), Angelica tenuissima (AT), Mentha arvense (MA), and Artemisiae argyi (AA), were investigated on LPS-stimulated inflammation using Raw 264.7 cells. The volatile flavor extracts of CO and AG considerably inhibited LPS-stimulated NO, $PGE_2$, IL-6, and TNF-${\alpha}$ (except AG) production, as well as iNOS expression. Major volatile components of CO were identified as ligustilide and of ${\beta}$-eudesmol as AG by GC-MS analysis. Thus, these results suggest that the volatile extracts of CO and AG may be useful as potential therapeutic agents for inflammation-associated disorders.

Volatile flavor components of Angelica gigas Nakai affected by different storage time and temperature were investigated. The aroma compounds was extracted by a simultaneous distillation and extraction method using a Likens and Nickerson's apparatus. The concentrated extract was analyzed and identified by GC and GC-MS equipped polar and nonpolar column. The yields of volatile concentrates of Angelica gigas Nakai by low temperature storage were larger than those by room temperature storage. The GC patterns of the flavor components of both resembled but the peak area of each flavor compounds was little different. Main volatile flavor components of Angelica gigas Nakai by using polar column were ${\alpha}-pinene$, ${\beta}-pinene$, terpineol, farnesol, cadinene, guaiol, isolongifolene and eudesmol etc. Main volatile flavor components of Angelica gigas Nakai by using nonpolar column were camphene, ${\beta}-pinene$, elemol, eudesmol etc.
