Three new arylnaphthalene lignans, named neojusticin C (1), procumbenoside C (2) and procumbenoside D (3), have been isolated from the whole plant of Justicia procumbens, together with three known ones, justicidinoside B (4), justicidinoside C (5), and diphyllin-1-O-beta-D-apiofuranoside (6). The complete assignments of 1H and 13C NMR data for three new lignans were first obtained by means of 2D NMR techniques, including HSQC and HMBC.
从爵床全草中分离出三种新的芳基萘木脂素，分别命名为新爵床苷C（1）、匍匐苷C（2）和匍匐苷D（3），以及三种已知的木脂素，爵床苷B（4）、爵床苷C（5）和双叶豆素-1-O-β-D-芹菜呋喃糖苷（6）。借助二维核磁共振技术，包括异核单量子相干谱（HSQC）和异核多键相关谱（HMBC），首次完成了三种新木脂素的氢谱（1H NMR）和碳谱（13C NMR）数据的全归属。
