Abstract
Salvianolic acid L. a rosmarinic acid dimer, was isolated from Salvia offic inalis and identified as 7,8-dihydroxy-2-(3,4-dihydroxyphenyl)-1,2-dihydron aphthatene-1,3-dicarboxylic acid di(1-carboxy-2-(3,4-dihydroxyphenyl))ethyl ester. Two novel hydrolytic products 7,8-dihydroxy-2-(3,4-dihydroxyphenyl) -1,2-dihydronaphthalene-1,3-dicarboxylic acid and the corresponding 3-monoe ster were also isolated and characterized. Salvianolic acid L showed strong free radical scavenging activities for DPPH and superoxide anion radicals. (C) 2001 Published by Elsevier Science Ltd.
