利用顶空固相微萃取方法对桑叶茶中的挥发性成分进行提取，并用气相色谱-质谱联用技术（GC-MS）对化合物进行分析和分类，并经过NIST05谱库检索对比。结果表明：在桑叶茶中共检测出42种挥发性成分，主要有醛类10种、酮类9种、醇类4种、酯类3种、酸类2种、烃类10种、杂环类化合物4种，其中含量较高的化合物为醛类、酮类，分别占总化合物含量的24.67%、22.36%。

Volatile components in mulberry leaf tea were extracted by headspace solid phase micro extraction method using gas chromatography-mass spectrometry (GC-MS) technique. NIST 05 spectrum-search showed that 42 volatile compounds existed in mulberry leaf tea, including 10 aldehydes, 9 ketones 4 alcohols, 3 esters, 2 acides, 10 alkanes and 4 other compounds. Among the volatile compounds, aldehydes and ketones showed high contents, being of 24.67% and 22.36%, respectively.
