Chemical constituents from aerial parts of Fallopia dumetosum / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical constituents from aerial parts of Fallopia dumetosum.</p><p><b>METHOD</b>The 80% ethanol extract was separated by means of silica gel and Sephadex LH-20 column chromatography. The compounds isolated from the plant were identified by physicochemical properties and spectroscopic evidence.</p><p><b>RESULT</b>Ten compounds were obtained and identified as emodin (1), physcion (2), quercetin (3), luteolin (4), 5"- methoxy-hydnocarpin (5), ethylparaben (6), protocatechuic acid (7), (2S,3S, 4R) -sphinganine-(2'R) -delta5'6' (E) -2'-hydroxyl tetracosanoylamino (8), beta-sitosterol (9), and daucosterol (10).</p><p><b>CONCLUSION</b>Anthraquinones and flavones were the major constituents of this plant. All compounds were isolated firstly from this plant, and compounds 5, 7, and 8 were isolated from the genus Fallopia for the first time.</p>
