摘要：

A new lactone having a characteristic sweet and fruity aroma was isolated as a trace component from the juice of Malus x domestica var. Orin. The structure of the lactone was elucidated as 4,8-dimethyinon-7-en-4-olide (1) by the spectroscopic evidences and synthesis. The chiral GC analyses of the natural and the synthesized lactones revealed that the R/S ratio of the lactone in the apple juice is 23/77. The odoriferous properties of the both enantiomers are also described. Copyright (C) 2004 John Wiley Sons, Ltd.
