Retention of Volatile Constituents in Dried Toona sinensis by GC-MS Analysis.

Toona sinensis, whose young leaves and shoots are edible and nutritious, is a perennial deciduous tree vegetable. In this paper, the volatile constituents of dehydrated fresh young leaves of Toona sinensis obtained by different drying methods were micro-extracted in solid-phase, and then analyzed with gas chromatography-mass spectrometry (GC-MS). The major flavor components include caryophyllene, aromadendrene, nonadecane, and phytol. Comparing with convection oven drying and natural solar drying, vacuum drying and microwave drying can preserve most of the original flavors of Toona sinensis. [ABSTRACT FROM AUTHOR]
