为深入研究和厚朴的化学成分，采用毛细管气相色谱－质谱联用技术法分析了和厚朴（Ｍａｇｎｏｌｉａｏｂｏｖａｔａ）的挥发油成分。结果共分出了７５个成分，并对其中２９个成分进行了鉴定，占挥发油总量的９０％。大于１％的成分有９个，以α－桉叶油醇（α－ｅｕｄｅｓｍｏｌ，约３７％）、β－桉叶油醇（β－ｅｕｄｅｓｍｏｌ，约２０％）及δ杜松烯（δ－ｃａｄｉｎｅｎｅ，约１０％）为主。
In order to further study the chemical composition of honokiol, the volatile oil composition of Magnolia obovata was analyzed by capillary gas chromatography-mass spectrometry. A total of 75 components were identified and 29 of them were identified, accounting for 90% of the total volatile oil. There are 9 components with more than 1% of α-eudesmol (about 37%), β-eudesmol (about 20%) and δ-cadinene (δ-cadinene). About 10%) mainly.
