In this study, Korean medicinal herb extracts were investigated for their in vitro effect on anti-hypertensive activities, including nitric oxide (NO) production in the human umbilical vein endothelial cell line EA.hy529 and angiotensin-converting enzyme (ACE) activity. Traditional remedies related to the treatment of hypertension were identified using DongUiBoGam, the most comprehensive source for Korean traditional pharmacopoeia. Herbal remedies were selected by translating the symptom terminology into westernized medicinal terms using the Korean classification of disease in Oriental medicine and Korea Traditional Knowledge Portal. Seven types of herb extracts were selected and screened for in vitro anti-hypertensive activities. Among the extracts, those of Evodiae fructus, Bambusae caulis in Taeniam, Sophorae fructus, Melonis calyx, and Schizonepeta rhizome produced significant increases in NO production, although their ability to inhibit ACE were weaker. Using Fourier transform ion cyclotron resonance mass spectrometry, the major flavonoids exhibiting anti-hypertensive activities were identified: quercetin, apigenin, and luteolin. Our results indicate that these medicinal herbs are potent natural anti-hypertensive agents that can be developed for clinical therapies. In addition, our systematic approach to identifying candidate herbal remedies in the traditional Korean pharmacopoeia can be used to search for additional traditional remedies, such as for hypoglycemia and obesity.

The aim of this study was to investigate the effects of dried garlic flesh and dried juice of garlic flesh on the body fat and lipid metabolism of 9-month-old rats with diet-induced obesity. For 8 weeks, the rats were fed either a control diet or experimental diets containing 3 or 5%(w/w) of dried, powdered garlic flesh or garlic juice. In our study, body weight gains and calorie efficiency ratios were the lowest in 5% dried garlic flesh treatment. Hepatic diacylglycerol acyltransferase (DGAT) activities were inhibited relatively to the control for the dried garlic flesh treatments. Fecal total lipid excretion, plasma total lipid,and triglyceride concentrations were significantly improved through the 5% dried garlic flesh treatment. In conclusion,garlic consumption reduced the body fat and improved lipid profile in rats. Especially, consumption of dried garlic flesh was turned out to be more effective than the intake of dried garlic juice.
