摘要:

著名藏药白花刺参Morina nepalensis var. alba Hand. Mazz.的全株的水溶性部分通过硅胶、RP-8、Sephadex LH-20柱层析分离,得到4个咖啡酰基奎宁酸14 ,运用光谱和波谱方法,  分别鉴定为3-O-咖啡酰基奎宁酸(1)、3, 5-O-双咖啡酰基奎宁酸(2)、3, 4-O-双咖啡酰基-奎宁酸(3)和4, 5-O-双咖啡酰基-奎宁酸(4). 应用2D NMR图谱, 对其氢和碳的化学位移进行全归属, 并报道1, 2在氘代甲醇和氘代二-甲亚砜两种溶剂下测定1H和13C化学位移. 4个化合物都是首次分离自刺参属植物.

Abstract:

Four compounds were isolated from water-soluble part of whole plant of Morina nepalensis var. alba Hand.-Mazz.by CC on Si gel, RP-8, Sephadex LH-20. Based on spectroscopic evidences,  their structures were elucidated as 3-O-caffeoyl-quinic acid (1), 3, 5-O-dicaffeoyl-quinic acid (2), 3,  4-O- dicaffeoyl-quinic acid (3] ) and 4, 5-O- dicaffeoyl-quinic acid (4), respectively. Complet e assignments of 1H and 13C spectra of these four compounds were obtained by 2D NMR spe ctra. Furtherm ore, 1H and 13C Chemical shifts of compound 1 and 2 were determined with both in CD3OD and DMSO-d6 solvent. All four compounds were firstly isolated from the Morin a plants. 

Key words: morina nepalensis var. alba Hand.-Mazz, dipsacaceae, morina, caffeo ylquinic acids, NMR complete assignments
