The chemical constituents of the wood of Xanthoxylum nitidum (ROXB.) D. C.(Fagara nitida ROXB.) were examined. Two phenylpropanoids, methyl nitinoate (2) and dihydrocuspidiol (3), and a benzodioxane type lignan, nitidanin (4), were newly isolated. The structures of the phenylpropanoids were chemically determined. In addition, the application of a selective insensitive nuclei enhanced by polarization transfer selective (INEPT) technique in the NMR spectrum to the new lignan allowed us to deduce the structure.
对光果黄椒木(Xanthoxylum nitidum (ROXB.) D. C.,也称为Fagara nitida ROXB.)的木材化学成分进行了研究。新分离出了两种苯丙烷类化合物,分别是甲基尼丁酸酯(2)和二氢磐石醇(3),以及一种苯并二噁烷类型的木脂素,尼丁醇(4)。通过化学方法确定了这些苯丙烷类化合物的结构。此外,应用选择性不敏感核增强极化转移选择性(INEPT)技术于新的木脂素的NMR光谱,帮助我们推断出其结构。
