Abstract

Two new neolignan glycosides, davidioside A (1) and davidioside B (2), have been isolated along with six known compounds from the branch bark of Davidia involucrata. Identification of their structures was achieved by 1D and 2D NMR experiments, including (1)H-(1)H COSY, NOESY, HMQC, and HMBC methods as well as FAB mass spectral data.

摘要

从珙桐的树枝树皮中分离出了两种新的新木脂素糖苷，珙桐苷A（1）和珙桐苷B（2），以及六种已知化合物。通过一维和二维核磁共振实验，包括（1）H-（1）H COSY、NOESY、HMQC和HMBC方法以及快原子轰击质谱数据确定了它们的结构。
