본 연구에서 8종의 생약 추출물이 A. parasiticus의 배양시 aflatoxin $B_1$ 생성에 미치는 효과를 조사하였다. 배지의 pH는 배양 3일 후에 모든 생약 추출물이 pH 4 이하를 나타냈으며 구기자, 오매, 계피, 두충은 배양 6일에 다시 pH 4 이상으로 상승하였고 이중 대추가 배양 기간 중 가장 낮은 pH를 나타냈다. 균체 생성량은 모든 실험군이 대조군보다 높았으며 갈근, 두충, 오미자, 대추, 오매,구기자, 목과의 순으로 나타났다. 이중 갈근이 최대 생성량을 나타냈으며 목과가 가장 낮은 생성량을 나타냈다. Aflatoxin $B_1$은 갈근과 대추 추출물을 제외한 모든 실험군에서 생성이 억제되었다. 특히 계피, 오매, 두충 구기자, 오미자 추출물 에서 aflatoxin $B_1$ 생성이 현저히 저하되었으며 계피가 가장 큰 억제 효과를 나타냈다. 균체량이 많이 생성되면 aflatoxin $B_1$ 생성이 적어지고 균체량이 적게 생성되면 aflatoxin $B_1$의 생성이 많아졌다. Aspergillus parasiticus에 의해 aflatoxin $B_1$을 가장 적게 생성하는 계피와 가장 많이 생성하는 갈근 추출물의 총단백질 생성량은 계피는 3일째 (34.5%), 갈근 ext ract는 4일째 (36.4%) 총단백질의 함량이 최대가 되어 균체 내의 총단백질의 함량은 계피와 갈근 추출물을 첨가한 시험군이 게조군의 총단백질 함량 (32.7%)보다 약간 많았으며 aflatoxin $B_1$ 생성 및 축적이 최대가 되는 시기는 총단백질량이 최대가 되는 시기보다 대체로 1일 정도 늦게 나타났다.

Objectives： Presently Mume Fructus (MF) undergoes fumigation, which produces benzo[a]pyrene. As a primary analysis with the aims to minimize the production of benzo[a]pyrene and to suggest standards for processing the MF, the steaming method was chosen among the various processing methods, and reviewed through a series of experiments.Methods： Methods：Pitted and un-pitted MF were steamed and processed into samples. After testing level of benzo[a]pyrene, the samples were analyzed for amount of polyphenol and flavonoids. Scavenging activities of the samples for the DPPH and ABTS radicals were tested. In order to measure anti-inflammatory effects of the samples, cell survival rate was investigated using CCK-8 Assay. Also, water extracts of dried and steamed MF were administered to the RAW 264.7 cells to compare expressions of NO, PGE₂, IL-1β, and TNF-α. In addition, anti-diarrhea effects of the herbal medicine were tested on animal models with diarrhea induced by MgSO₄ and Castor oil.Results： Regardless of pitting, processed MF contained no benzo[a]pyrene. Anti-oxidation effect increased in relation to the frequency of steaming process. However, extracts of dried and steamed MF suppressed different kinds of inflammation factors, and extract of dried MF showed superior anti-diarrhea effect than extract of steamed MF.Conclusions： It is suggested that steaming method of MF is recommended for processing the herbal medicine without the production of benzo[a]pyrene. But regarding that dried and steamed MF showed differences in their anti-oxidative, anti-inflammatory, and anti-diarrhea effects, it is recommended to perform further researches on different efficacies of MF according to their processing methods.

By analysing the benzo(a)pyrene concentration using HPLC-FLD and LC-MS/MS, pollution levels of herbal medicines without permitted benzo(a)pyrene specification were investigated. Average benzo(a)pyrene concentrations were 38.30, 37.46 and 21.22 ㎍/kg for Amomi Tsao-ko Fructus, Mume Fructus and Coptidis Rhizoma, respectively, which are 4 to 7 times higher than maximum permitted benzo(a)pyrene concentration of Rehmanniae Radix Preparata and Rehmanniae Radix, i.e. 5.0 ㎍/kg. Proportion of detected samples exceeding 5.0 ㎍/kg benzo(a)pyrene concentration was 22% for Cimicifugae Rhizoma and Scrophulariae Radix, 44% for Forsythiae Fructus, 67% for Mume Fructus, 100% for Amomi Tsao-ko Fructus and Coptidis Rhizoma, and collectively 29% (36 out of 125 samples) in average. In terms of risk characterization results, human exposure of benzo(a)pyrene were 7.96, 3.49 and 1.61 ng/kg b.w./day and the margin of exposure(MOE) were 1.25 × 10⁴, 2.86 × 10⁴ and 6.20 × 10⁴ for Mume Fructus, Amomi Tsao-ko Fructus and Coptidis Rhizoma, respectively. MOE banding of those herbal medicines was categorized to 'low concern'. However, considering that human exposure of benzo(a)pyrene for food is legislated to 1.4~2.5 ng/kg b.w./day, it was urgent to set up the guideline of benzo(a)pyrene in herbal medicines.

The purpose of this study was to provide basic data regarding the perceptions of medicated diets among chefs. The subjects were 22 exemplary restaurant chefs in the Danyang area. The results showed that 40.9% of the chefs regarded the taste of medicated diets as good. Conversely, 22.7% of the subjects answered that they didn't know about medicated diets. Mass media and education from relevant institutions were the means of acquiring information about medicated diets. The chefs recognized that varieties of sauce could make medicated diets popular because of special flavor. Female chefs were generally more familiar with herbs than male chefs. Overall, the chefs were not familiar with Menthae Herba, Atractylodis Japonica, Adenophorae radix, Caryophylli Flos, or Carthami Flos. However, they were familiar with Glycyrrhizae Radix, Cassiae Semen, Cinnamomi Cortex, Polygonati Rhizoma, Mume Fructus, and Ginseng Radix, even though they didn't like the tastes pertaining to medicated diets. Ginseng Radix was the most well-known oriental herb, and Mume Fructus and Rubi Fructus were also popular. The most popular cooking methods for medicated diets were, in order, boiling rice, roasting items, and preparing the herbs as beverages.

Objectives: The purpose of this study was to examine the effects of Ohmae-hwan (OMH) and Mume Fructus (MF) on inflammatory bowel disease (IBD). Methods: Mice were divided into 4 groups: a normal group, control group, MF group, and OMH group. Three groups, excluding the normal group, were fed a 5% solution of dextran sulfate sodium (DSS) in water for 10 days to induce inflammatory bowel disease. From the fourth day of DSS treatment, the control group was given distilled water only, the MF group was given MF powder in distilled water, and the OMH group was given dried OMH extract powder in distilled water for 7 days. Results: For each animal, changes in body weight, colon length, and component levels in blood and colon tissues after each treatment were noted. The weight in the control group and MF group decreased slightly compared with that in the OMH group, and the colon length in the MF group and OMH group was more than that in the control group. TNF-α and WBC were decreased in both the MF group and the OMH group. RBC was increased in the OMH group, like in the normal group, compared with the control group and MF group. Hb and PLT of each group were not significantly different. Regarding changes in the colon tissues, both the MF group and OMH groups recovered similar to the normal group. Conclusions: Thus, treatment with OMH and MF seems to be effective against inflammatory bowel disease, and OMH is likely to increase body weight and induce RBC recovery better than MF.

Objectives : The aim of this study was to evaluate the effect of aqueous extracts of Mume Fructus(MF) on the 6-n-propyl-2-thiouracil(PTU)-induced rat hypothyroidism.Methods : Aqueous extracts of MF(yield = 19.38%) were administered, once per day for 42 days from 2 weeks before starting of PTU treatment as an oral dose of 300 and 150 ㎎/㎏(body weight), and hypothyroidism was induced by daily subcutaneous treatment of PTU 10 ㎎/㎏ for 28 days. The changes in the body weight, thyroid gland weights, liver weight, serum levels of thyroid hormone-thyroid stimulating hormone(TSH), tri-iodothyronine(T₃) and thyroxine(T₄), total cholesterol, low density lipoprotein(LDL), high density lipoprotein(HDL) and triglyceride (TG), aspartate aminotransferase(AST), alanine aminotransferase(ALT), liver antioxidant defense system-lipid peroxidation, H₂O₂, superoxide dismutase(SOD) and catalase(CAT) were examined with histopathology of thyroid glands and liver.Results : Results were compared with LevoT₄0.5 ㎎/㎏ treated rats. MF extracts recovered from the decreases in the body weight, liver weight, T₃and T₄, TG, liver CAT activities as results of PTU treatment. And MF extracts recovered from the increases of thyroid gland weights, TSH, HDL contents, liver H₂O₂, AST as results of PTU treatment. In addition, these PTU-induced histopathological changes in thyroid glands and liver related to hypothyroidism were dramatically decreased by treatment of both different dosages of MF extract, respectively.Conclusions : According to the above results, it is suggested that MF extracts have advantageous effects on the thyroid hormone productions with beneficial effects on the hypothyroidism related liver injuries mediated by the modulation on the antioxidant system.

The Mume Fructus (MF) has been used for relieves cough, arrests arrest chronic diarrhea, treat fluid depletion, and treat ascariasis in Korea. In this study, a high-performance liquid chromatography (HPLC) method was established for simultaneous determination of six main components of MF. Additionally, we were investigated the anti-inflammatory and anti-allergic effects of MF extract on lipopolysaccharide (LPS)-treated RAW264.7 cells and tumor necrosis factor (TNF)-${\alpha}$/interferon (IFN)-${\gamma}$-treated HaCaT cells. The analytical column for separation was used a Gemini $C_{18}$ column maintained at $40^{\circ}C$. The mobile phase consisted of 1.0% (v/v) acetic acid in water (A) and 1.0% (v/v) acetic acid in acetonitrile (B). The flow rate was 1.0 mL/min and the detector was a photodiode array (PDA) set at 280 nm and 320 nm. We evaluated the inhibitory effect of MF extract on the production of inflammatory markers, nitric oxide (NO) and prostaglandin $E_2$ ($PGE_2$) in LPS-stimulated RAW264.7 cells and thymus- and activation-regulated chemokine (TARC/CCL17) in TNF-${\alpha}$/IFN-${\gamma}$-treated HaCaT cells, respectively. We confirmed the genes expression related with TARC, macrophage-derived chemokine (MDC/CCL22) and regulated on activation, normal T cell expressed and secreted (RANTES/CCL5) in HaCaT keratinocyte cells by MF extract. The contents of the five compounds in MF were 0.22-1.01 mg/g. Also, the MF extract show inhibition of about 78% and 75% on NO and $PGE_2$ production at the concentration 1000 mg/mL in RAW264.7 cells. MF extract suppressed the hTARC level and genes expression such as TARC, MDC, and RANTES on TNF-${\alpha}$/IFN-${\gamma}$-treated HaCaT cells.

Objectives : Previous studies have shown that Fructus mume (FM) has anti-platelet effects. The present study was performed to determine the acute oral toxicity and quality control of a crude extract of FM in ICR mice. Methods : We investigated the in vivo single dose acute toxicity of FM 95% ethanol extract. This test was orally administered once by gavage to 20 male and 20 female mice at dose levels of 0 (control group), 1250, 2500 and 5000mg/kg body weight, respectively. Mortalities, clinical findings, autopsy findings and body weight changes were monitored daily for the 14 days following the administration. HPLC analysis was performed for the simultaneous determination of ursolic acid and p-hydroxycinnamic acid in FM. Reverse-phase chromatography using a C18 column and photodiode array detection at 211 nm was used for quantification of the two maker components. The mobile phase for gradient elution consists of water and acetonitrile. Results : We observed survival rates, general toxicity, change of body weight, and autopsy. The mice did not die after single oral administration of maximum dose of FM. Autopsy of animal revealed no abnormal gross finding. Therefore, $LD_{50}$ value of FM for ICR mice was more than 5000mg/kg on oral route. The HPLC analysis showed that ursolic acid and p-hydroxycinnamic acid amounts to 9.75- and 0.12% in the extract with the retention times of 47.99- and 15.38 minutes, respectively. Conclusions : These results suggest that no toxic dose level of FM in mice is considered to be more than 5000mg/kg. Consequently, it was concluded that FM have no effect on acute toxicity and side effect in ICR mice. For the quality control of FM extract, simultaneous determination of ursolic acid and p-hydroxycinnamic acid was established.

Protein tyrosine phosphatase 1B (PTP1B) is predicted to be therapeutic target in treatment of type 2 diabetes and obesity. Thus, in order to search for PTP1B inhibitors, we screened the inhibitory activity of PTP1B in the water extracts of 84 medicinal herbs. Among them, the extracts of Pini Folium, Magnoliae Cortex, Artemisiae asiaticae Herba, Schizonepetae Herba, Menthae Herba, Mume Fructus, Cimicifugae Rhizoma, and Amomi Cardamomi Fructus showed relatively significant (58-68%) inhibitory activity against PTP1B. Especially, the methylene chloride fraction of the methanol extract of Menthae Herba (81% inhibition at 30 ${\mu}g$/ml) showed more potent inhibitory activity against PTP1B than others.
