摘要： Four esters have been isolated from a Chinese medicinal herb, fruit of Alpinia galanga(L.) Swarts, and identified as 1'-acetoxychavicol acetate(1), trans-p-acetoxycinnamyl acetate(2), 1'-acetoxyeugenol acetate(3), and trans-3'-acetoxytsoeugenol acetate(4). Among them compound 2 has not been reported in literature and compound 4 has nor been found in natural product before. Compound 1 and 3 were hydrclysed rapidly in boiling wacerinto 1'-hydroxychavicol acetate(5), tians-p-acetoxycinudmic alcnhol (6), 1'-hydroxyeugenol acetate (7) and trans-3' - hydroxyisoeueugenol acetate(8) respectively. The mechanism of these hydrolyses is discussed. The mass spectrometric fragmentations of these compounds are proposed.
