This study investigated the relaxation effects of Crataegi Fructus(CF, Crataegus pinnatifida Bunge) on the contraction evoked by phenylephrine in rabbit carotid artery, and also analyzes antioxidative status in vitro. CF revealed siginificant relaxation on phenylephrine-induced arterial contraction. It's relaxant effect statistically significant in both in the presence of endothelium and absence of endothelium, but statistically exerted more strong relaxation in the presence of endothelium. CF increased in vitro nitric oxide(NO) production in dose-dependent manner. Also, they reduced malondiaidehyde(MDA) concentrations, phosphatidyl choline-liposome(PCOOH) contents, linoleic acid-induced lipid peroxidation and exerted 1,1-diphenyl-2- picryl-hydrazyl(DPPH) radical scavenging effect, in vitro. These results indicate that Crataegi Fructus would be effective in relaxing arterial contraction and it's antioxidative effects may be involved in endothelium-dependent relaxation of artery via vascular protective properites.

To clerify the antioxidant effect of Crataegi Fructus (CF) extract on reactive oxygen species (ROS), The C6 glioma cells were treated with various concentrations of hydrogen peroxide ($H_2O_2$). The $H_2O_2$-induced neurotoxicity was measured by XTT assay for the cell viability. For the protective effect of CF extract on the cytotoxicity induced by $H_2O_2$, cell viability, lactate dehydroganase (LDH) activity, and the inhibitive activity of lipid peroxidation of CF extract were performed. In this study, $H_2O_2$ decreased cell viability dose- and time-dependent manners and increased LDH activity compared with the control. In the protective effect on $H_2O_2$, CF extract increased cell viability and decreased LDH activity on $H_2O_2$-induced cytotoxicity, lipid peroxidation by FTC assay. From these results, It is suggested that $H_2O_2$ was highly toxic on cultured C6 glioma cells, and also, CF extract showed the protective effect on $H_2O_2$-mediated cytotoxicity.

It had been known for a while that Crataegi Fructus(CF; Crataegus pinnatifida Bunge) had only a digestive effect. Recently, it has been demonstrated that CF also has an anti-hypertensive effect. However, its mechanism of relaxant effect has not been investigated yet. This study was examined to investigate the mechanism of vascular relaxation effect of CF in isolated rat thoracic aorta. CF revealed significant relaxation to phenylephrine(PE)-induced arterial contraction but much less to KCI-induced one. When CF was pretreated, it inhibited PE-induced contraction non-competitively. Methylene blue(10/sup -6/M) completely blocked the relaxant effect of CF whereas L-NAME(10/sup -5/M) did almost completely. However, atropine(10/sup -6/M) did not have any influence on vascular relaxation effect of CF. Regarding cNOS activity, CF significantly increased its activity from rat whole brain homogenate in a dose dependent manner which was inhibited by L-NAME(10/sup -5/M). On the other hand, CF did not affect on expression of TNF-α mRNA in RAW 264.7 cells, suggesting that CF is not related to iNOS activity. These results indicate that CF would be effective in relaxing vascular contraction through release of endothelial nitric oxide.

The mixture of Ginseng Radix and Crataegi Fructus (Gen-CF) was developed to increase the pharmacological effect of ginseng in the treatment of hypercholesterolemia and prevention of cardiovascular disease. This study evaluated the effects of Gen-CF on serum lipids of hypercholesterolemic rats in vivo, as well as its antioxidant activities in vitro, and explored its clinical effects on patients with hypercholesterolemia. In vitro, Gen-CF displayed 1,1-diphenyl-2-picrylhydrasyl and superoxide radical scavenging activities, and inhibited hemolysis induced by 2,2'-azobis-2-amidinopropane dihydrochloride in a dose-dependent manner. In vivo, Gen-CF significantly inhibited the increases of total cholesterol, low-density lipoprotein cholesterol and triglyceride in high cholesterol-diet and Triton WR-1339 models. It also significantly inhibited the decrease of high-density lipoprotein cholesterol in these models. In the clinical trial, Gen-CF significantly lowered total cholesterol, low-density lipoprotein cholesterol, triglyceride, total lipid and phospholipid, with no adverse events, including hepatic or renal toxicity. The data suggest that Gen-CF has the potential to treat hypercholesterolemia and prevent cardiovascular disease.

Objectives : Non-alcoholic fatty liver disease (NAFLD) is characterized by the accumulation of hepatic triglycerides (TG) that leads to inflammation and fibrosis. Crataegi Fructus ethanol extract (CE) is a korean traditional herb that used for digestive diseases. It has been investigated that CE has the effect that prevent hepatotoxicity caused by CCl4 or GaIN and regulate the inflammatory in several organs. However, a hypolipidemic effect of CF has not been reported. Methods : The purpose of this study is that examine the lipid accumulation inhibitory effect of CE on NAFLD. We checked the body and liver weight change of MCD-diet induced mice with/without administration of CE. The blood lipid levels of C57BL/6J mice were checked by biochemistry. Also we observed the liver histology of MCD-diet induced mice and investigate the molecular mechanisms in MCD-diet-induced NAFLD in C57BL/6J mice. Results : CE improved MCD-diet-induced lipid accumulation and TG and TC levels. Also, CE decreased hepatic lipogenesis such as SREBP-1, $C/EBP{\alpha}$, $PPAR{\gamma}$, ACC and FAS. Besides, we also found out that CE increased AMPK phosphorylation. These results indicated that CE has the same ability to activate AMPK and then reduce SREBP-1, and FAS expression, finally leading to inhibit hepatic lipogenesis and hepatic antioxidative ability. Conclusions : In this report, we found CE exerted a regulatory effect on lipid accumulation by decreasing lipogenesis in MCD-diet induced NAFLD model. Therefore, CE extract may be active in the prevention of fatty liver.

This study investigated the physiological characteristics of various medicinal plant extracts including Crataegi Fructus (CF), Perilla frutescens Britton var. acuta Kudo (PF), Geranium thunbergii sieb. et Zucc. (GT) and Polygonum multiflorum Thunberg (PM) for use in extending the shelf-life and improving the functional properties of seasoned pork. CF and GT showed a wide spectrum of antimicrobial activities against 5 kinds of Gram (+) bacteria and 5 kinds of Gram (-) bacteria. The antimicrobial activities of the extracts decreased as the heat treatment temperature increased between 60 and $121^{\circ}C$, but their activities remained relatively high following heat treatment. The total phenolic compound contents of the CF, PF, GT, PM extracts were 66.2, 29.0, 96.6 and 13.3 mg/g, respectively. The order of their DPPH radical scavenging activity was GT > CF > PF > PF. The nitrite scavenging activities of the CF, PF and GT extracts at 0.1% concentration were 10.5, 1.6 and 3.8%, respectively. The GT extract (99.7%) showed the highest degree of lipid rancidity inhibition compared to CF (90.3%), PF (88.9%) and PM (41.2%). After heat treatment for 15 min at $121^{\circ}C$, the DPPH radical scavenging activity of CF decreased but it increased in GT and PM. The nitrite scavenging activities of CF and GT decreased after heat treatment for 15 min at $121^{\circ}C$ but remained at relatively high levels. Also, degrees of lipid rancidity inhibition remained relatively high in PF (86.3%) and GT (99.8%) after heat treatment for 15 min at $121^{\circ}C$. These results suggest that CF and GT extracts could be used as ingredients in seasoning sauce to improve the shelf-life and functional properties of seasoned pork.
