Background: Angelica gigas, A. sinensis, and A. acutiloba are commercially important in the herbal medicine market, and among them, A. gigas has the highest economic value and price. However, their similar morphological traits are often used for fraud. Despite their importance in herbal medicine, recognition of the differences between Angelica species is currently inadequate. Methods and Results: A multiplex polymerase chain reaction (PCR) method was developed for direct detection and identification of A. gigas, A. sinensis, and A. acutiloba. The gene for the distinction of species was targeted at ITS in the nucleus and trnC-petN gene in chloroplasts. The optimized multiplex PCR in the present study utilized each Angelica species-specific primer pairs. Each primer pair yielded products of 229 base pairs (bp) for A. gigas, 53 bp for A. sinensis, 170 bp for A. acutiloba. Additionally non-specific PCR products were not detected in similar species by species-specific primers. Conclusions: In the present study, a multiplex-PCR assay, successfully assessed the authenticity of Angelica species (A. gigas, A. sinensis, and A. acutiloba). and whole genome amplification (WGA) was performed after DNA extraction to identify, the species in the product. The detection method of raw materials developed in the present study could be applied to herbal medicine and health functional food management.

Alimentotherapy refers to the treatment or prevention by means of food. As food is consumed in everyday life and its constituents varies enormously. the practice of alimentotherapy was often misunderstood. By the research on ancient classics we could find 3 prospective about this practice. Firstly, alimentotherapy was used during the recovery and also for prevention. This is a type of Life-nurturing method, which we suggest to be called life-nurturing alimentotherapy. Secondly, it was also used as a dietary prescription made by physicians. Sometimes they made prescriptions combining materials derived from food with herbal medication. This practice was exclusively made by physicians as they had to consider the characteristic of each food as well as the condition of the patient. Thirdly, sometime alimentotherapy was used in cuisine form. They used food components in major part and herbal medicine used as additional ingredients. It was primarily focused on the taste and in some part its functional aspects. The underlying theories in alimentotherapy is exactly the same as used for understanding herbal medicine in TKM. Therefore, except in the case of life-nurturing method, it should be used by expert physicians. Finally, we suggest to differentiate the terms of alimentotherapy in the aspect of life-nurturing, dietary prescriptions and cuisine to prevent confusions.

This study evaluated the hypolipidemic effects of Eleutherococcus senticosus combined with several oriental medicinal herbs. In addition, it addressed whether consuming a diet of healthy food along with a daily supplement of this composite could affect the health status of individuals suffering from diet-related disease such as obesity and hyperlipidemia. The effects of the combined medicinal herbal extracts(MHE) extracted with hot water on reducing serum lipids and improving blood parameters were examined in rats fed a high-fat diet for 5 weeks. Sprague-Dawley rats were randomly assigned to 4 groups: basal diet only(BDG), high fat diet without MHE(FCG), high fat diet and 10% MHE(F10E) and high fat diet and 20% MHE(F20E). Serum lipid contents and blood variables were examined after the experimental period. The results of were as follows. The hematological data for the 4 groups were similar indicating no significant differences. There were moderate level of serum GOT activity in the F10E and F20E groups as compared to the FCG group. Total cholesterol, LDL-cholesterol, triglyceride in serum and the atherogenic index were remarkably reduced in the MHE-supplemented groups as compared to the control group. However, F10E and F20E groups had significantly higher HDL-cholesterol levels than the control group. These results imply that combination of several medicinal herbal extracts could be used to reduce of serum lipid concentrations. The data from this study will be used as basic information with the field of functional food research to address how we can apply oriental medicinal resources to foods. Such research currently drawing considerable attention world-wide.

We investigated changes in quality during storage of cookies prepared with pine needle powder these are functional foods. We chose the quantity of pine needle powder (0%, 3%, 6%, or 9%, by weight) and storage time (1 day, 3 days, or 5 days) as independent variables and conducted sensory tests, measured chromaticity, and investigated physical properties. Differences in sweetness (p<0.05), bitterness and overall preference (both p<0.001), were noted on sensory testing, and were all significant. The degrees of brightness (p<0.001), redness (p<0.001), yellowness (p<0.001), and hardness (p<0.05) increased significantly as pine needle powder content increased, and changes in brightness and redness (both p<0.01) during storage were also significant.

Objective: Functional dyspepsia refers to sustainable or repetitive pain at upper stomach related with food intake. This research was intended to observe the improvement of the symptom by administering Bowhatang to a number of functional dyspepsia patients and to clarify its clinical effects. Method: The research was performed upon the appropriate 36 patients conforming to the criteria after being diagnosed with functional dyspepsia among the 87 patients who visited the department of internal medicine at Gumi Oriental Hospital of Daegu Haany University for digestive diseases and were administered with Bowhatang. Result: 91.8% of the patients had upper stomach globus symptoms. which is of the largest percentage. and 13.5% had hunger pain. which is of the least percentage. After administering Bowhatang. by and large Likert scale was significantly reduced. According to the subjective improvement evaluation by the patients. 32 patients(86%) were improved. and 3 patients(8%) had neither improvement nor relapse. while 2 patients ( 6%) were relapsed. Conclusion: Bowhatang has shown significant improvement about the symptoms for functional dyspepsia patients. It is predicted when more outcomes become available from researches on side effects or toxicity of Bowhatang later on. it will be more often used in the clinic.

A mushroom as a functional food material is being increasingly used in these days. It has been that about 1,500 species of mushrooms grow naturally in Asia. Among them about 700 species are edible, but about 30-50 species are poisonous. Even a poisonous mushroom is a very interesting subject for the dietary life research from biochemical viewpoint due to the fact that any mushroom can be the physiological active material. Not a few identified poisonous materials are being used as research reagents thus far. It is suggested that more useful materials could be obtained by progresses in future researches. The identification of the poisonous ingredient can open up a route for mushroom intoxication cure. It is known that cell destruction and troubles on skin, liver, and kidney troubles can be occurred from mushroom intoxication. Recently the author reported as a collection of treatises regarding anti-tumor substances of mushroom (2005), antibiotic substances of mushroom (2006), living-body functional and control substance (2007), and medicinal mushroom commonly used in Korean herbal medicines (2008). In this sequel, published research data on protoplasm, nerve, stomach and intestines, malodor, and acute pain poison of mushroom are collected and reported.

During menopause, elderly woman experience physical and emotional symptoms, including hot flashes, night sweats, weight gain, vaginal dryness, and mood swings. In this study, we investigated the effects of mixed herbal extracts containing Angelica gigas Nakai and Cuscuta chinensis Lam. on menopause symptoms in ovariectomized (OVX) rats. Daily oral treatments of 500 mg/kg and 1,000 mg/kg in OVX rats for 8 weeks significantly reduced weight gain, inhibited hepatic lipid accumulation, and lowered serum lipid levels comparable to the effects induced by estradiol treatments. Mixed herbal extracts (named Jaeummidan) also prevented vaginal dryness as measured by increased vaginal weight. Increased vaginal weight was associated with enlarged epithelium thickness. These data show the preventive actions of Jaeummidan against menopause symptoms and further suggest the possibility of developing functional ingredients in elderly human populations experiencing menopause symptoms.

In this study, a peptide exhibiting antioxidant activity was isolated from sandfish (Arctoscopus japonicus) roe hydrolysate (SRH) in order to evaluate their practical uses as materials for manufacturing functional foods. The A. japonicus roe protein was hydrolyzed using Collupulin MG, and isolation of antioxidant peptide was performed using ultrafiltration (UF), prep-HPLC, and RP-HPLC. The SRH with a molecular weight below 3 kDa constituted about 38% of the whole hydrolysate, and the fraction with a molecular weight below 3 kDa showed significantly greater antioxidant activity compared to the original SRH and other fractions. The isolation fold of the antioxidant peptide isolated from SRH throughout the four-step procedure was 7.11-fold, and protein yield was 14.8%. The DPPH radical scavenging activity of isolated antioxidant peptide was above 90% at a concentration of 1.0 mg/mL, which was similar to that of the Trolox at a concentration of 0.1 mg/mL. These results suggested that the antioxidant peptide derived from A. japonicus roe could be a useful additive for producing functional foods and protein supplements. However, it is necessary to perform further study the structural characteristics of this antioxidant peptide isolated from A. japonicus roe.

Angelica gigas Nakai (A. gigas) easily changes its color during storage, and appropriate thermal treatment can improve storage stability through inactivation of enzymes such as polyphenol oxidase. Therefore, this study was performed to determine quality characteristics of dried A. gigas in response to high-temperature-short-time (HTST) treatment during storage. Dried A. gigas were treated at 120-180℃ for 10 min, the samples were stored at 4℃ and 50℃ for 10 weeks, and used for the analysis of qualities. Concerning the color values, the sample treated at 120℃ was similar to the control, and the color change was large when treated above 180℃. However, color difference (ΔE⁎ab) was lower in treated samples than in control. Browning index was similar for all the samples except for the sample treated at 180℃. Functional qualities (phenolics content, antioxidant activities, and level of major components) showed a slight difference according to storage periods in all samples without control, and nodakenin content was observed in control. The results of this study showed that HTST treatment improved storage stability such as stability of colors and browning index in dried A. gigas during storage, and the appropriate treatment temperature was 120℃ in terms of stability in color and browning index.
