摘要:研究了杜仲内树皮及其抽提物的一般物、矿物质、脂肪酸与单糖的化学组成。结果表明,碳水化合物(92.97%)、钙(5.1769mg/g)、α-亚麻酸(27.4%)及葡萄糖(130.51mg/g)分别是杜仲内树皮的一般物、矿物质、脂肪酸与单糖的主要组成成分。采用Sephadex LH-20柱色谱及薄层色谱等方法,从其70%丙酮提取物水溶性部分分到5种化合物,经波谱分析及理化性质化舍物分别鉴定为:紫云英苷(1)、异槲皮苷(2)、槲皮素-3-O-木糖葡萄糖苷(3)、异绿原酸A(4)、异绿原酸C(5)。化合物3—5为首次从该植物中分得。
Chemical compositions, including proximate composition, mineral, fatty acid and monosaccharide compositions of inner barks and extractives of the Eucommia ulmoides Oliv. were studied. Carbohydrate ( 92.97 % ) was the major constituent in proximate composition of E. ulmoides inner barks. The most quantitatively abundant constituents of fatty acid, mineral and monosaccharide compositions were α-linolenic acid ( 27.4 % ), Ca ( 5. 176 9 mg/g ) and glucose ( 130. 51 mg/g ), respectively. From the water soluble fraction of E. ulmoide inner barks, 5 compounds were isolated and their structures were elucidated as astragalin ( 1 ), isoquercetrin (2), quercetin-3-O-xyloglucoside (3), isochlorogenic acid A (4) and isochlorogenic acid C (5) by spectroscopic analyses and chemical evidence. Compounds 3-5 were isolated for the first time from this species.
