Abstract
Six compounds were isolated from the 75% ethanol extract of Nitraria tangutorum seed.On the basis of spectroscopic methods including 1H NMR,13C NMR and ESI-MS and comparison with literature,their structures were elucidated as daucosterol(1),4-hydroxypipecolic acid(2),quercetin(3),allantoin(4),1,2,3,4-tetrahydro-1-methyl-β-carboline-3-carboxylic acid(5) and L-tyrosine(6).Compounds 1,2,3,5 and 6 were isolated from Nitraria tangtorum for the first time.关键词
