ABSTRACT
To study the chemical constituents of the branches of Tamarix rasissima, repeated silica gel column chromatography, Sephadex LH-20 chromatography and recrystallization were applied for chemical constituents isolation and purification. Ten phenolic compounds were isolated from the n-BuOH fraction and their structures were elucidated by physical properties and spectra analysis such as UV, ESI-MS and NMR as monodecarboxyellagic acid (1), ellagic acid (2), 3, 3'-di-O-methylellagic acid (3), 3, 3'-di-O-methylellagic acid-4-O-beta-D-glucopyranoside (4), 3, 3'-di-O-methylellagic acid-4'-O-alpha-D-arabinfuranoside (5), ferulic acid (6), isoferulic acid (7), caffeic acid (8), 4-O-acetyl-caffeic acid (9), and 4-methyl-1, 2-benzenediol (10). All compounds except for isoferulic acid were isolated firstly from this plant except for isoferulic acid, and compounds 5, 9 and 10 were obtained from Tamarix genus for the first time.
