100 residual pesticides in 1,565 medicinal herbs being on sale in Seoul was analyzed by a simultaneous multiresidue method. The recovery ratio was 71.0~119.7%. The detection rate of pesticide residues was 5.3% and the rate of excess to Maximum Residue Limits (MRLs) was 0.9% of the total samples. The medicinal herbs which had the high detection rate of residual pesticides were Alismatis Rhizoma, Citri Unshii Pericarpium, Lycii Fructus and Zyzyphi Fructus. The medicinal herbs detected pesticide over Maximum Residue Limits (MRLs) were Alismatis Rhizoma (4), Cnidii Rhizomain (4), Chrysanthemi Zawadski Herba (1), Citri Unshii Pericarpium (1), Lycii Radix Cortex (1), Menthae Herba (1), Schisandrae Fructus (1) and Taraxaci Herba (1). The residual pesticides which had the high detection frequency were cypermethrin, chlorpyrifos, phenthoate, endosulfan, isoprothiolane, chlorothalonil and chlorfenapyr. Estimated Daily Intake (EDI) of detected pesticides was compared to Acceptable Daily Intake (ADI) in order to assess risk. Ethoprophos detected in Cnidii Rhizomain showed the highest %ADI, 26.85. And pyraclofos and endosulfan in Cnidii Rhizomain, endosulfan and isoprothiolane in Alismatis Rhizoma and cyprodinil in Taraxaci Herba showed more than 1 %ADI, but others showed below 1 %ADI.

This study was conducted to investigate the relationships between yearly variations of climatic factors and yearly variations of productivity in Alisma plantago L. In addition, correlation coefficients among yield and yield components were estimated. The data of yield and yield components were collected from the Statistical Year Book of Seungju province, Reserach Report of Seungju Extension Station of Rural Development Administration, and farmers for 10 years from 1983 to 1992. The meteorological data gathered at the Seungju Weather Station for the same period were used to find out the relationships between climatic factors and productivity. Yearly variation of the amount of precipitation in October and the minimum temperature in November were large with coefficients of variation(C.V.) of 106.44, 144.08%, respectively, but the variation of the average temperature, maximum temperature, minimum temperature from July to September were relatively small. Fresh weight and dry weight of roots vary greatly with C. V. of 30.62, 31.85%, respectivly. Plant height and stem length show more or less small C. V. of 5.51, 6. 26%, respectively and leaf width, leaf length, number of stems and root diameter show still less variation. Correlation coefficients between maximum temperature in November and plant height, stem diamter, number of stems, root diamter and dry weight of roots are positively significant at the 5% level. There are high signficant positive correlations observed, between yield and yield components. The maximum temperature would be used as a predictive variable for the estimation of dry weight of roots and number of stems. Simple linear regression equations by the least square method are estimated for number of stems $(Y_1)$ and the maximum temperature in November(X) as $Y_1=4.7114+0.5333\;X\;(R^2=0.4410)$, and for dry weight of roots$(Y_2)$ and the maximum temperature in November(X) as $Y_2=55.0405+14.3233\;X\;(R^2=0.4511)$

Interrelation between the antioxidative activity of hot-water extracts of 130 medicinal plants and their cellular antimutagenic activity was investigated. Antioxidative activity was evaluated by assaying electron-donation to DPPH free radical and scavenging of hydroxyl radical $({\cdot}OH)$ generated through Fenton rection, respectively. All medicinal plants examined in this study exhibited markedly electron-donating ability and radical scavenging ability in each assay system. The results demonstrated the fact that Pilbal (Piper longum L.) is the strongest in electron-donating activity, on the other hand, that Seokgok (Dendrobium moniliforme L.) is the strongest in ${\cdot}OH$ scavenging activity. When evaluated their antioxidative activities, 24 medicinal plants including Jimo (Anemarrhena asphodeloides Bunge) were found to be the medicinal plants carrying strong antioxidative activity, which exhibited more than 50% activity compared to the control group in both electron-donating and free radical scavenging. The experiment was also performed to examine whether 11 medicinal plants having significant antimutagenicity damage DNA in the presence of $Cu^{2+}$, showing the fact that all samples tested, except Taeksa (Alisma canaliculatum All. Br.), Paekjain (Nitraria sibirica Pall) and Ohyak (Lindera strychifolia Sieb. et Zucc. Villar) are capable of inducing DNA strand break. We also found that Taeksa and Paekjain strongly block DNA strand break induced by chemical mutagen mitomycin C.

Reactive oxygen species(ROS) or free radicals are produced in the pathogenesis of human diseases including atherosclerosis, diabetes, cancer, and aging. Antioxidants are associated with the prevention of ROS-induced tissue and cellular damage in the various diseases. This study investigated the antioxidative activities of the methanol extract of Alisma plantagoaquatica var. orientale and its main component under conditions of radical generation using allophycocyanin and ferric-thiocyanate assay. Alisol B 23-acetate as a main component was isolated from the methanol extract of Alisma plantago-aquatica var. orientale. In results, the extract of Alisma plantago-aquatica var. orientale showed inhibitory activity on AAPH [2,2'-azobis(2-amidinopropane)dihydrochloride]-induced protein oxidation. Also, the extract of Alisma plantago-aquatica var. orientale and alisol B 23-acetate inhibited lipid peroxidation. These results indicate that Alisma plantago-aquatica var. orientale and alisol B 23-acetate show promise as therapeutic agents for various damages involving free radical reactions.

Objectives : This study was designed to investigate the effect on lipoapoptosis of Alisma orientale extract against free fatty acid-induced cellular injury. Methods : HepG2 cells were used in an vitro model. HepG2 cells were treated with free fatty acids to generate a cellular model of nonalcoholic fatty liver disease (NAFLD). Using this cellular model, the anti-apoptotic effect and reducing steatosis of Alisma orientale extract against free fatty acid-induced cellular injury was evaluated by measuring steatosis and apoptosis. Results : Alisma orientale extract significantly attenuated free fatty acid-induced intracellular steatosis. Alisma orientale extract inhibited free fatty acid-mediated activation of pJNK, PUMA, BAX, caspase-3, and -9, and apoptotic kinases that are correlated with NAFLD. Alisma orientale extract also promoted Bcl-2, a anti-apoptotic protein. Conclusions : From the above, the Alisma orientale extract decreased the hepatocyte steatosis and showed the hepatocelluar protective effect by the regulation of apoptosis-related protein. It proposes the possibility of Alisma orientale extract to the treatment of nonalcoholic fatty liver disease in clinics.

Objectives : Effects of Rhizoma Alismatis extract on lipid composition and TBARS (thiobarbituric acid reactive substances) formation were investigated in rat fed high fat diet. Methods : Seventy male Sprague-Dawley rats were used in these experiments and housed with food and water ad libitum and Twenty rats were selected healthy over 400g body weight and fed high fat diet for 8 weeks. Rhizoma Alismatis extract was administerd at dose 100mg/kg/day, 200mg/kg/day and 300mg/kg/day p.o. for 4 weeks. Then Triglyceride, Total cholesterol, HDL-cholesterol, LDL-cholesterol, TBARS concentration and ALT(Alanine Aminotransferase), AST(aspatate transaminase) activities were determined. Results : Plasma total LDL-cholesterol showed a tendancy to decrease in all treated group(P<0.05), however plasma HDL-cholesterol, total cholesterol, triglyceride showed no significantly different. Rhizoma Alismatis extract feedings resulted in a decrease in plasma TBARS(p<0.05) concentration and AST, ALT activites but contents of TBARS in liver showed no significantly different among all the treatments. Conclusions : Reviewing these experimental results, it appears that Rhizoma Alismatis extract was effective for inhibiting lipid peroxidation and decreasing LDL-cholesterol concentration.
