A new lignan 1 was isolated together with the five known lignans 2-6 and four sesquiterpenes 7-10 from the seeds of Magnolia praecocissima. The structure of 1 was elucidated by analysis of spectroscopic data and chemical reaction. Furthermore, the absolute configurations of 1, 2, and 3 were determined by the modified Mosher's method.
从早花玉兰种子中分离得到一种新的木脂素1，以及五种已知木脂素2 - 6和四种倍半萜7 - 10。通过光谱数据分析和化学反应阐明了1的结构。此外，采用改进的莫舍尔法确定了1、2和3的绝对构型。
