The purpose of this study is to investigate prevents hypertension effect of ethanol extract of Sigesbeckia pubescens. In this study, to determine prevents hypertension effect of ethanol extract S. pubescens on suppression of calcium mobilization force in vascular smooth muscle cell line. Ethanol extract of S. pubescens,showed a moderate suppression of calcium mobilization force effect vascular smooth muscle cell line. Therefore, treatment with ethanol extract of S. pubescens may accelerate blood flow through dilatation of the blood vessel. This result suggest a potential role of ethanol extract of S. pubescens as source of prevents hypertension agent.

The tetra-aza macrocyclic ligand. 1.5,6.8.12.13-hexamethyl-1.4.8.11-tetraazacyclotetradeca-4.11-diene(C), was prepared as its dihydroperchlorate salt by the non-template condensation of 3-methyl-3-buten-2-one with N-methylethylenediamine. The Ni(II) and Cu(II) complexes of C were obtained by the reaction of its metal salts and C. These complexes were identified by the elemental analysis. iH(13C)-NMR. IR. and UV-vis. spectroscopy. Based on the result of NMR spectrum, it was found that this complex might be N-meso. The axial ligation of nitrogenous base(imidazole) to the Ni(II)-(A. B, C) complexes were investigated in nitromethane. The equilibrium constants for the ligation reactions of nickel complexes were determined using the spectrophotometric method at 15-45 C . In case of Ni(II)-A complex the equilibrium constants K were larger than Ni(II)-B and C complexes, depending on basicity of the ligand nitrogen.
