摘要
Sir new phenolic constituents, L-malic acid 2-O-(1), mucic acid 2-O-(5), mucic acid 1,4-lactone 2-O-(6), 5- O-(8), 3-O- (10), and 3,5-di-O- (11) gallates, were isolated from the fruit juice of Phyllanthus emblica together with their methyl esters (2-4, 7, 9), and their structures were determined by spectral and chemical methods, Compounds 5. 6, and 8, the major phenolic constituents of the juice, were present as an equilibrium mixture in aqueous solution.
