利用水蒸气蒸馏法提取得到辛夷不同部位的挥发油，并用 Ｇ Ｃ－ Ｍ Ｓ联用技术进行了定性分析和定量分析，测得辛夷皮、心和全蕾出油率平均分别为０．８４％ ，５．２％ 和２．４％ ；共鉴定出３４ 种组份，分析表明：不同部位挥发油组份相近，但出油率相差悬殊．
The volatile oil from different parts of Magnolia biondii was extracted by steam distillation, and qualitative analysis and quantitative analysis were carried out by G-M S method. The average extraction rates of Magnolia bark, heart and whole bud were 0.84% 5.2% and 2.4%. A total of 34 components were identified. The analysis showed that the components of volatile oil in different parts were similar, but the oil yield was quite different.
