为了研究藏药臭蚤草的浩性成分,我们利用各种柱色谱技术,从藏药臭蚤草甲醇提取物的乙酸乙酯萃取相分离到4个化合物,通过1D、2DNMR、MS和HRMS等试验,鉴定为2,4-dihydroxy-6-methyl—ethanone-4-O-β-D—Glc(1),4-(3’-hydroxypropyl)-2,6-dimethoxyphenol-3’-O-β-D—glcoside(2),4-allyl-2-methoxyphenol-1-O-β-gleo—side(3),2-methyl-1,3,6-trihydroxy-9,10-anthraquinone-3—O-(6'-O-Ac)-α—L—Rha-(1→2)-β-D—Gle(4),其中化合物1—3为苯丙素苷类化合物,化合物4为蒽醌苷。化合物1—4都是首次从该属植物中分离得到,化合物1为新的苯丙素苷类化合物。
In order to investigate the bioactivity constituents of Tibetan folk drug Pulicaria insignis, four compounds were isolated with chromatography techniques. Structures were elucidated to be 2,4-dihydroxy-6-methyl-ethanone-4-O-β-D- Glc ( 1 ), 4-'( 3'-hydroxypropyl ) -2,6-dimethoxyphenol-3 '-O-β-D-glcoside ( 2 ), 4 -allyl-2 -methoxyphenol- 1 -O-β-D-glcoside ( 3 ), 2-methyl- 1,3,6 -trihydroxy-9, 10 -anthraquinone-3-O- ( 6'-O-Ac ) -α-L-Rha- ( 1 →2 ) -E-D-Glc ( 4 ) on the basis of spectroscopic analysis including 1D,2D-NMR, MS and HRMS. Four compounds were isolated from the genus Pulicaria for the first time. 2,4-Dihydroxy-6-methyl-ethanone-4-O-β-D-Glc( 1 )is a new phenylpropanoid glycoside.
