Six secondary metabolites, including two novel iridoids, longifolides A (1) and B (2), were isolated by various chromatographic methods from a methanol extract of branches and leaves of Morinda longifolia Craib. The structures of the compounds were determined on the basis of NMR spectroscopic (1H and 13C NMR, HSQC, HMBC, 1H-1H COSY, NOESY) and FTICR-MS data, as well as by comparison of them with literature values.
通过各种色谱方法，从长叶酸藤子（Morinda longifolia Craib）枝叶的甲醇提取物中分离出六种次生代谢产物，包括两种新型环烯醚萜，长叶酸藤子苷A（1）和长叶酸藤子苷B（2）。根据核磁共振光谱（1H和13C NMR、HSQC、HMBC、1H-1H COSY、NOESY）和傅里叶变换离子回旋共振质谱数据，并与文献值进行比较，确定了这些化合物的结构。
