Abstract

Three new water-soluble constituents [ficuscarpanoside B (1), (7E,9Z)-dihydrophaseic acid 3-O-beta-D-glucopyranoside (4) and ficuscarpanic acid (6)] and the natural product 2,2'-dihydroxyl ether (7) have been isolated, together with three known compounds [(7S,8R)-syringoylglycerol (2), (7S,8R)-syringoylglycerol-7-O-beta-D-glucopyranoside (3) and icariside D2 (5)] from the aerial roots of Ficus microcarpa. Identification of their structures was achieved by 1D and 2D NMR experiments, including 1H-1H COSY, NOESY, HMQC and HMBC methods and FAB mass spectral data.

摘要

从榕树气生根中分离出了三种新的水溶性成分[无花果卡帕诺苷B（1）、（7E，9Z）-二氢苯甲酰甲酸3-O-β-D-吡喃葡萄糖苷（4）和无花果卡帕酸（6）]以及天然产物2,2'-二羟基醚（7），同时还分离出了三种已知化合物[（7S，8R）-丁香酰甘油（2）、（7S，8R）-丁香酰甘油-7-O-β-D-吡喃葡萄糖苷（3）和淫羊藿苷D2（5）]。通过一维和二维核磁共振实验，包括1H-1H 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。
