Isolation and structure identification of chemical constituents from Anabasis brevifolia / 药学学报

ABSTRACT

<p><b>AIM</b>To study the chemical consitituents of the n-butanol-extracts of Anabasis salsa and Various chromatographic techniques were used to the chloroform-extract of Anabasis brevifolia.</p><p><b>METHODS</b>separate and purify the constituents. Their physico-chemical properties and spectral data were used to elucidate their structures.</p><p><b>RESULTS</b>Five compounds were isolated and identified as 2-O-beta-D-glucopyranosyloxy-4,6-dimethoxy phenylenthanone (1), 2-O-(2)-beta-D-glucopyranosyloxy-4, 6-dimethoxy phenylenthanone (2), 3-methyl-but-2-enoic acid-[2-(4-methoxy phenyl)-ethyl]-amide (3), 5,6,7,2'-tetramethoxy isoflavonoid (4), 2'-hydroxy-5,6,7-trimethoxyisoflavonoid (5).</p><p><b>CONCLUSION</b>Compounds 2, 3, and 5 are new compounds. And the others were isolated from Anabasis L. for the first time.</p>
