| Abstract: |
| 80% acetone extracts of the fresh leaves of Alchornea trewioides was successively separated by Sephadex LH-20,MCI gel CHP 20P, and Toyopearl Butyl-650C column chromatography to yield ten phenolic acids and related compounds. Their structures were elucidated by spectroscopic analyses as:salicylic acid(1),p-hydroxybenzoic acid(2),2,5-dihydroxybenzoic acid(3),3,4-dihydroxybenzoic acid(4),trans-p-coumaric acid(5),cis-p-coumaric acid(6),caffeic acid(7),caffeic acid methyl ester(8),gallic acid(9),and methyl gallate(10). Compounds 1-8,10 were isolated from the Alchornea for the first time. |
