泽泻化学成分的分离与鉴定

Isolation and Identification of Chemical Constituents from Alisma orientale

运用色谱分离技术,从泽泻科泽泻中分离得到7个化学成分,其结构用各种光谱技术(包括红外光谱、质谱、一维和二维核磁共振谱)鉴定为4-pyrazin-2-yl-but-3-ene-1,2-diol,烟酰胺,甘油棕榈酸酯,1-monolinolein,11-deoxyalisol,alisol A 24-acetate及alisol C 23-acetate.其中,4-pyrazin-2-yl-but-3-ene-1,2-diol、烟酰胺、甘油棕榈酸酯和1-monolinolein为首次从泽泻科中获得.

The diuretic constituents are studied. Seven chemical constituents are isolated from Alisma orientale （Alismataceae） using column chromatography. They are identified as 4-pyrazin-2-yl-but-3-ene-1,2- diol, nicotinamide, glycerol palmitate, 1-monolinolein, 11-deoxyalisol A, alisol A 24-acetate and alisol C 23-acetate. Their structures are characterized by various spectroscopic technologies.
