Studies on polyphenolic chemical constitutents from root of Salvia yunnansis / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical constituents in the root of Salvia yunnansis.</p><p><b>METHOD</b>Compounds were isolated and purified by Diaion HP20, Sephadex LH - 20, ODS chromatography. Their structures were determined by spectral analysis and chemical evidence.</p><p><b>RESULT</b>Twelve compounds were isolated and identified from the root of S. yunnansis protocatechaldehyde (1), caffeic acid (2), ferulic acid (3), rosmarinic acid (4), salvianolic acid A (5), salvianolic acid C (6), lithospermicacid (7), lithospermicacid B (8), 9'-methyl lithospermate B (9), 9"'-methyl lithospermate B (10), 9',9'''-dimethyl lithospermate B (11), 9'-ethyl lithospermate B (12).</p><p><b>CONCLUSION</b>The compounds 1, 2, 3, 5, 6, 9, 10, 11 and 12 were first isolated from S. yunnanensis.</p>
