This study was conducted to investigate the residue amount of pesticide on the 41 medicinal herbs in Daejeon area. This study was carried out to monitor the current status of pesticide residues in commercial medicinal herbs for sale of food use in 2012. It was performed using GC/ECD, GC/NPD, HPLC to analyze pesticides residues. Residues of 283 pesticides were analyzed by a simultaneous multiresidue method in 41 medicinal herbs being on sale in Daejeon. The medicinal herbs detected pesticides in 10 of 41 cases, showed a detection rate of 24.39%. The medicinal herbs which exceed the maximum residue limit were five cases as Cnidii Rhizoma, Osterici Radix, Artemisiae Capillaris Herba, Zizyphi Fructus and Alismatis Rhizoma. And pesticide residue of Cnidii Rhizoma and Alismatis Rhizoma exceeds the limit standard presented in only medicine use of KFDA. The residual pesticides which had the high detection rate were Chlopyrifos, Tebuconazole and Endosulfan in the detection of medicinal herbs. For further research, standards of Pesticide Residues in medicinal herbs should be added and more research of pesticide residues in medicinal herbs required. And standards of pesticide residues in medicinal herbs should be applied equally as medicines and food.

Four protostane-type triterpenes, alisol B 23-acetate (1a), alisol C 23-acetate (2a), alisol B(3a), and alisol A 24-acetate (4a), were isolated from the rhizome of Alismatis plantago-aquatica L. var. orientale Samuelson (Alismataceae) and eleven protostane derivatives (compounds 1-11) were obtained by selective modification from alisol B 23-acetate (1a). These compounds were investigated for their anti-complement activity against the classical pathway of the complement system. Alisol B (3a) and alisol A 24-acetate (4a) exhibited anti-complement activity with $IC_{50} values of 150 and 130 \mu$ M. Among the synthetic derivatives, the tetrahydroxylated protostane triterpene (9) showed moderate inhibitory activity with $IC_{50} value of 97.1 \mu$ M. Introduction of an aldehyde group at C-23 (10; $IC_{50} value, 47.7 \mu$ M) showed the most potent inhibitory effect on the complement system in vitro.

In vivo antioxidant activities were screened over 30 kinds of crude drugs which are most frequently prescribed in oriental medicine. Of these, only Ginseng Radix, Cimicifugae Rhizoma, Zingiberis Rhizoma(steam dried), Alismatis Rhizoma, and Liriopes Tuber were shown to be positive in the activity.

Alismatis Rhizoma is originated from the rhizome of Alisma plantago-aquatica L. var. orientale Samuelson or A. canaliculatum A. Br. et Bouche (Alismataceae). Prostane-type triterpenes, guaiane-type sesquiterpenes, and kaurane-type diterpenes have been reported as the main canstituents from these plants. Four prostane-type triterpenes. alisol B 23-acetate (1). alisol C 23-acetate (2), alisol B (3). and alisol A 24-actate (4). were isolated from the EtOAc-soluble fraction of this dried rhizome.

A quantitative method for determining levels of three bioactive compounds based on pattern recognition was developed and fully validated for the quality control of Alismatis Rhizoma (AR) by HPLC. Separation conditions were optimised using an Optimapak $C_{18}$ column ($250mm{\times}4.6mm$, 5 ${\mu}m$) with a mobile phase of acetonitrile and 0.1% aqueous phosphoric acid and detection wavelengths of 205 and 245 nm. Method validation yielded acceptable linearity ($r^2$ > 0.9998) and percent recovery (98.06%-101.71%). Limits of detection ranged from 0.08 to 0.15 ${\mu}g/mL$. Levels of the three bioactive compounds, alisol C acetate, alisol B, and alisol B acetate, in AR were 0.07-0.45, 0.38-10.32, and 1.13-8.59 mg/g dried weight, respectively. Pattern analyses based on these three compounds were able to differentiate Chinese and Korean samples accurately. The results demonstrate that alisol B and its acetate may be used as marker compounds for AR quality and can be regulated to no less than 0.36 and 1.29 mg/g of dried sample, respectively. The method described here is suitable for quantitative analyses and quality control of multiple components in AR.

Objectives : This study aimed to evaluate the effects of Alismatis Rhizoma Herbal-acupuncture( AR-HA) at $KI_{10}$(Umgok) on nephritis induced by lipopolysaccharide(LPS) in rat. Methods : Rats were injected with LPS to induce nephritis. The rats in $KI_{10}$-AR-HA group were treated with AR-HA, $KI_{10}$-NP group with needle prick, $KI_{10}$-saline group with normal saline injection respectively at $KI_{10}$ three times for a week. Several experimental items were performed including measurements of the numbers of RBC, WBC, neutrophil in blood, the levels of creatinine, $TNF-{\alpha}$, CINC-1 in serum, creatinine, total protein in urine, MPO in kidney. Results : Needle prick stimulation at $KI_{10}$ significantly reduced WBC in blood of LPS-stimulated rats. Saline injection at $KI_{10}$ significantly reduced WBC in blood, $TNF-{\alpha}$ in serum, total protein in urine of LPS-stimulated rats. AR-HA at $KI_{10}$ significantly reduced WBC, neutrophil in blood, $TNF-{\alpha}$, CINC-1 in serum, creatinine, total protein in urine of LPS-stimulated rats. Conclusion : AR-HA at $KI_{10}$ has a therapeutic effect on nephritis in LPS-stimulated rat. There may be a synergism between $KI_{10}$(Umgok) stimulation and AR-HA solution.

Objectives : The researcher investigated the anti-obesity effect of Alismatis Orientale Rhizoma(AP) water extract in mice fed a high fat diet and focused on the analysis of local area adipose tissue. Methods : Male ICR mice were divided into three groups, which were fed either a normal AIN diet, a 45% high fat diet (CT group), or a high fat diet and orally administration with a concentrations of 100 mg/kg (AP100 group) and 300 mg/kg body weight (AP300 group) for eight weeks. Results : As compared with CT group, AP100 group showed significant reductions in absolute weight of liver. As compared with CT group, AP100 group and AP300 group showed significant reductions in weight gain and relative weight of total fat. AST, triglyceride, total-cholesterol levels from the AP 100 group and 300 group were significantly lower than those of the CT, and ALT, LDL-cholesterol levels from the AP 100 group was significantly lower than those of the CT. But serum HDL-cholesterol levels from the AP 100 group and 300 group were significantly higher than those of the CT. And serum adiponectin levels from the AP 100 group was significantly higher than those of the CT. In result of real time PCR, all mRNA expression(PEPCK, G6Pase, PGC-$1{\alpha}$ and $ERR{\gamma}$) of two experimental groups were significantly decreased compared to those of CT group. The treatment with AP on local abdominal area made a fat cell size lessen on the fat tissue in the abdominal cavity and subcutaneous area. Conclusions : These results suggest that AP has an anti-obesity effect and the effect is mediated by inhibition of fat gain.

In order to estimate accurate quality of crude drugs in which pest was found during the storage, damaged 15 items were collected on current markets. We identified insect name by investigation of insect morphology, bug cluster, and morphology of damaged crude drugs. Three kind of pests were identified in the above 15 items as follows: A: Pyralis sp. (Pyralidae) was observed in damaged Platycodi Radix. B: Anthreus verbasci (Anobiidae) was found out in damaged Angelicae gigantis Radix, and Dioscoreae Rhizoma. C: Stegobium pamceum (Anobiidae) was discovered in the 12 crude drugs as follows: Puerariae Radix, Angelicae koreanae Radix, Angehcae tenuissimae Radix, Codonopsis Radix, Ledebouriellae Radix, Ginseng Radix alba, Angelicae dahuricae Radix, Belamcandae Rhizoma, Paeoniae Radix, Cnidii Rhizoma, Alismatis Rhizoma, and Fritillariae Bulbus.

The current definition of Arismatis Rhizoma is the tuberous root of Alisma orientale Juzepzuk in the Korean Pharmacopoeia, but there is still no marker compound. So it has difficulties in quality control. Therefore, in this study, we have established a method to analyze alisol B and alisol B acetate using HPLC as a marker compounds of Arismatis Rhizoma. As the result of the analysis, alisol B content was ranged from 0.02% to 0.50% and alisol B acetate content was ranged from 0.12% to 0.25% in 40 samples. The stability of alisol B and alisol B acetate was investigated during 24 months. As a result, alisol B acetate was significantly decreased. The marker compound of Arismatis Rhizoma is alisol B acetate and the content of 0.05% or more is suitable by applying the stability results.
