OBJECTIVE: To investigate the chemical constituents of Ehretia thyrsiflora. METHOD: Compounds were isolated by using silica gel, Sephadex LH-20 and RP-C18 chromatography; their structures were elucidated by means of spectral data analysis. RESULT: Seven compounds were isolated and identified as methyl rosmarinate (1), caffeic acid (2), quercetin (3), kampferol (4), kaempferol 3-O-alpha-D-arabinoside (5), quercetin 3-O-alpha-D-arabinoside (6), and p-hydroxy benzoic acid (7). CONCLUSION: All these compounds were isolated from E. thyrsiflora for the first time. Compounds 2-7 were isolated from genus Ehretia for the first time. |
