Angelicae gigantis radix is the root of the perennial plant, which belongs to the family Umbelliferae. However, this herbal drug is represented quite different chemical components according to its different genus name, though other herbal drugs (i.e. Leonuri Herba, Xanthii Fructus and so on) show similar constituents on the same name. The root of Angelica gigas containing the coumarin compounds is commonly used in Korea, while Angelica sinensis and Angelica acutiloba including phthalide compounds are used in China and Japan, respectively as Angelicae gigantis radix. In this paper, a nearinfrared spectroscopic method was developed to determine genus name of Angelica spp., especially A. gigas and A. sinensis which are commonly misused in herbal markets. X-ray fluorescence spectrometry and electronic nose have been also applied as nondestructive methods to discriminate A. gigas from A. sinensis according to their specific properties.

Objectives : This study was performed to investigate the anti-fibrogenic effect of Angelica Gigantis Radix on cultured rat hepatic stellate cells. Materials and Methods : Hepatic stellate cells(HSC-T6) were treated with various concentrations of Angelica Gigantis Radix extract for both 24 and 48 hours. The extraction was done either with distilled water or 80% EtOH. After the treatment, cell viability, cell proliferation, procollagen production and the mRNA expression of the ASMA, TIMP1, TIMP2, procollagen Type 1a2, and Cytokine IL-6 production were measured by using MTT assay, BrdU assay, RT-PCR, procollagen Type I C-peptide EIA and IL-6 ELISA assay. Results : The cell viability treated with water extraction was significantly increased, but there were no significant changes treated with 80% EtOH extraction. The cell proliferation treated with water extraction decreased only in the 24 hours group, while there were significant decreases either in the 24 and 48 hours groups treated with 80% EtOH extraction. The mRNA expressions of the ASMA, TIMP2 and procollagen 1a2 decreased in a concentration-dependent manner in the 48 hours group. Procollagen production decreased in a concentration-dependent manner in both the 24 and 48 hours groups. Cytokine IL-6 production increased in a concentration-dependent manner in both the 24 and 48 hours groups. Conclusion : These results suggest that Angelica Gigantis Radix is beneficial in the treatment of cirrhotic patients as well as for patients with chronic hepatitis.

Objectives: This study used the basic principle of Oriental medicine, the sovereign, minister, assistant and courier principle (君臣佐使論) to investigate the effects of the component of ONGABO, which is composed of Ginseng Radix (Red Ginseng), Angelica Gigantis Radix, Schisandrae Fructus, Cuscuta Semen and Curcumae tuber on the viability of HepG2 cells. Methods: Single and mixed extracts of the component of ONGABO were prepared by lypohilizing powder of Red Ginseng (6-year root from Kanghwa), Angelica Gigantis Radix, Schisandrae Fructus, Cuscuta Semen, Curcumae Tuber (from Omniherb Co., Ltd., Korea) at the laboratory of herbal medicine in Woosuk University and were eluted after being macerated with 100% ethanol for three days. The cell viability of HepG2 was determined by using an absorptiometric analysis with PrestoBlue (Invitrogen) reagent after the plate had been incubated for 48 hours. All of the experiments were repeated three times to obtain the average value and standard deviation. The statistical analysis was done and the correlation factor was obtained by using Microsoft Office Excel 2007 and Origin 6.0 software. Results: Although Ginseng Radix (Red Ginseng) and Schisandrae Fructus did not enhance the viability of HepG2 cells, they were shown to provide protection of those cells. On the other hand, Angelica Gigantis Radix decreased the viability of HepG2 cells significantly, Cuscuta Semen and Curcumae Tuber had a small or no effect on the viability of HepG2 cells. Conclusions: In the sovereign, minister, assistant and courier principle (君臣佐使論), Ginseng Radix (Red Ginseng) corresponds to the sovereign component because it provides cell protection effects, Angelica Gigantis Radix corresponds to minister medicinal because it kills cells, Schisandrae Fructus corresponds to the assistant medicinal to help red ginseng having cell protect effects. Cuscuta Semen and Curcumae Tuber correspond to the courier medicinal having no effect in cell viability in HepG2. We hope this study provides motivation for advanced research on the sovereign, minister, assistant and courier principle.

Angelicae gigantis Radix (dried root of Angelica gigas) including major bioactives such as decursin and decursinol angelate provides rich flavors and several healthy benefits. Recent studies have shown that ultrafine powders of herbal medicines provide better physical properties and biological activities. Thus, ultrafine Angelica powder was added into the oligosaccharide syrup to provide flavors and healthy benefits in this study. Angelicae gigantis Radix was pulverized into d(0.1) = 3.220, d(0.5) = 7.822, and d(0.9) = 7.817 $\mu$m respectively using an air-flow mill. The ultrafine Angelica powder was added into the oligosaccharide syrup process with different ratios of water to oligosaccharide syrup at 1:5, 1:8, 1:11, and 1:14. The physicochemical properties such as viscosity and bulk density were measured. The Stokes' law was applied to predict the sedimentation velocity of the added Angelica powder in the syrup. The Angelica syrup prepared in this experiment showed good stability since the Angelica particles precipitated down slowly. The ratio of water to oligosaccharide syrup at 1:11 showed the optimal preparation in terms of the stability and the viscosity. The ultrafine-sized herbal powders such as Angelicae gigantis Radix have potentials for various food and pharmaceutical applications.

A reversed-phase liquid chromatographic method for decursin and decursinol angelate of Angelicae gigantis Radix, an important crude drug in Korean traditional medicine, was developed and validated. Decursin and decursinol angelate, the structure isomer (pyranocoumarin) each other, are the main organic constituents in Angelicae gigantis Radix. This method was developed using a RP-18 column, UV detector at 280 nm and 50% acetonitrile solution containing 0.01 M sodium dodecyl sulfate and 25 mM sodium dihydrogen phosphate (pH 5.0) as the mobile phase. Various validation parameters were included and evaluated satisfactorily. Linearity was established in range 2-75 mg/ml of decursin and decursinol angelate (correlation coefficient = 0.9997 and 0.9995, respectively). This analytical method showed good accuracy (98.1% and 99.5%, respectively). Precision (repeatability) revealed a relative standard deviation value of 1.71% (decursin) and 3.19% (decursinol angelate). For intermediate precision measure the considered variables were equipment and days. A robustness test showing the influence of deferent counter-ion concentration in mobile phase was also performed.
