The purpose of this study was to investigate the biological activities of cultivated Angelica gigas Nakai (CAG) and wild Angelica gigas Nakai (WAG) extracts prepared by extraction with water, 30% ethanol, 60% ethanol, or 90% ethanol. The electron donating ability of the WAG extracts was higher than that of the CAG extracts and 0.1% and 1.0% solutions of the comparative substance, L-ascorbic acid. The superoxide dismutase-like activity of the CAG extracts was higher than that of WAG extracts. Superoxide dismutase-like activity was highest (33.95%) in the CAG water extract. The total polyphenol content was highest in the 60% ethanol extracts of WAG. The nitrite scavenging ability of the CAG and WAG extracts was highest at a pH of 1.2. The tyrosinase inhibitory effect was highest (43.72%) in the water extract of WAG. The angiotensin converting enzyme inhibitory activity was highest (83.84%) in the 60% ethanol extract of WAG. The results of the present study will be useful for understanding the antioxidant and angiotensin-converting enzyme inhibitory activities of Angelica gigas Nakai extracts.

Objectives : Gliosis becomes physical and mechanical barrier to axonal regeneration. Reactive gliosis induced by middle cerebral artery occlusion is involved with up-regulation of CD81 and GFAP (Glial fibrillary acidic protein). The current study is to examine the effect of the Angelica gigas Nakai(intravenous injection. 100 mg/kg twice in a day) on CD81 and GFAP of the rat in the brain after middle cerebral artery occlusion. Methods : Cerebral infarction was induced by middle cerebral artery occlusion. And after intravenous injection of water extract of Angelica gigas Nakai, the size of cerebral infarction was measured. Examination of optical microscope were also used to detect the expression of CD81 and GFAP in the brain of the rat. Results : The following results were obtained : We found that size of cerebral infarcion induced by MCAO (Middle Cerebral Artery Occlusion) in rats were decreased after intravenous injection of Angelica gigas Nakai. We injected the extract of Angelica gigas Nakai to the MCAO in rats, and the optical microscope study showed that Angelica gigas Nakai had effect on protecting the cells of hippocampus. We found that GFAP, CD81 and ERK of the brain in rats with cerebral infarction after MCAO were meaningfully decreased after intravenous injecting Angelica gigas Nakai. We found that c-Fos expression of the brain in rats with cerebral infarction after MCAO were significantly increased after intravenous injecting Angelica gigas Nakai. Conclusions : These results indicate that Angelica gigas Nakai could suppress the reactive gliosis, which disturbs the astrocyte regeneration in the brain of the rat with cerebral infarction after MCAO by controlling the expression of CD81 and GFAP. And the effect may be modulated by the up-regulation of c-Fos and ERK.

Background: The objective of this study was to make colloidal dispersions of the active compounds of radix of Angelica gigas Nakai that could be charaterized as nano-composites using hot melt extrusion (HME). Food grade hydrophilic polymer matrices were used to disperse these compound in aqueous media. Methods and Results: Extrudate solid formulations (ESFs) mediated by various HPMCs (hydroxypropyl methylcelluloses) and Na-Alg polymers made from ultrafine powder of the radix of Angelica gigas Nakai were developed through a physical crosslink method (HME) using an ionization agent (treatment with acetic acid) and different food grade polymers [HPMCs, such as HP55, CN40H, AN6 and sodium alignate (Na-Alg)]. X-ray powder diffraction (XRD) analysis confirmed the amorphization of crystal compounds in the HP55-mediated extrudate solid formulation (HP55-ESF). Differential scanning calorimetry (DSC) analysis indicated a lower enthalpy (${\Delta}H=10.62J/g$) of glass transition temperature (Tg) in the HP55-ESF than in the other formulations. Infrared fourier transform spectroscopy (FT-IR) revealed that new functional groups were produced in the HP55-ESF. The content of phenolic compounds, flavonoid (including decursin and decursinol angelate) content, and antioxidant activity increased by 5, 10, and 2 times in the HP55-ESF, respectively. The production of water soluble (61.5%) nano-sized (323 nm) particles was achieved in the HP55-ESF. Conclusions: Nano-composites were developed herein utilizing melt-extruded solid dispersion technology, including food grade polymer enhanced nano dispersion (< 500 nm) of active compounds from the radix of Angelica gigas Nakai with enhanced solubility and bioavailability. These nano-composites of the radix of Angelica gigas Nakai can be developed and marketed as products with high therapeutic performance.

Angelica gigas Nakai is one of the most widely used herbal medicines and is known to have many pharmaceutical effects including an anti-oxidant, anti-cancer etc. This study was carried out to investigate an effect of fertilization on leaf yield, production of dry-matter and accumulation of pyranocurmarine compounds such as decursin (DE) and decursinol angelate (DA) in Angelica gigas Nakai. Effect of fertilization was determined from response surface regression equation composing of 2 by 3 factorial arrangement of urea, sodium dihydrogen phosphate and potassium chloride. Yield of leaf in Angelica gigas Nakai significantly increased until 100 days after transplanting. Production of leaf also tended to increase with increasing nitrogen fertilization. Model of regression equation showed that leaf production depended upon nitrogen ($Pr>{\mid}t{\mid}$ : 0.087, 0.256 and 0.079). Also, statistical results between nitrogen application level and production of dry-matter showed significant relationship (p<0.05) and contents of dry-matter was highest in 10 kg 10a-1 treatment on 24 Sep. Active compound isolated and purified from leaf and root of Angelica gigas Nakai was identified as DE and DA by gas chromatograph-mass spectrophotometry (GC-MS). Concentration of DA as prevalent compound in leaf was highest on 20 Aug. but decreased on 24 Sep. Amount of DE and DA accumulated in Angelica gigas Nakai significantly increased with growth stages and nitrogen level. The result of our investigation imply that nitrogen fertilization is important factor for production of leaf and accumulation of pyranocurmarine in Angelica gigas Nakai as a medicinal/food materials.

The objective of this experiment was to investigate the effect of feeding Angelica gigas Nakai by-products on performance and meat quality of Korean native chicks(KNC). Five hundred forty KNC were placed into 0, 0.2, and 0.4% Angelica gigas supplements with four replications between males and females. Weight gain, feed conversion ratio(FCR), breast meat lipid, fatty acid and protein contents were measured from 17 to 20 weeks old. Egg production, feed intake and FCR were examined from 22 to 29 weeks at four weeks at four weeks intervals. Basal diets based on corn and soybean meal contained 15% crude protein and 2,850㎉/kg ME for the growing period, 16.5% and 2,800㎉/kg for the laying period. Experiments were designed in a one way analysis. Weight gain of female chicks fed 0.2% Angelica gigas by-products increased significantly compared to that of other treatments for the growing period, but was not consistency in male groups. Moisture, protein, fat content were not statistically different among all treatments. Fatty acid composition(C16:0, C18:0) of chicks fed 0.2% Angelica gigas by-products was higher than other treatments. In laying period, hens fed 0.2 or 0.4% Angelica gigas Nakai by-products seemed to increase the egg production and significantly improved FCR compared to that of control(P〈0.05). Birds fed 0.4% treatment showed significantly the lowest feed intake and FCR of all treatments(P〈0.05). The results of these studies indicated that dietary supplemental Angelica gigas by-products may have a role to improve the performance of KNC.
