从云杉叶中分离得到一个新化合物2-hydroxy-4-[3’，5’-dihydroxyhexyl]phenyl-β-D-glucopyranoside(1)和5个已知化合物(2-6)。通过波谱技术，特别是二维核磁共振和MS数据分析，确定了它们的结构。这些化合物均为酚苷类化合物，均为首次从该植物中分离得到。化合物1对α-葡萄糖苷酶有中等抑制作用，IC50值为0.111 ± 0.061 mg/mL。
A new compound, 2-hydroxy-4-[3’,5’-dihydroxyhexyl]phenyl-β-D-glucopyranoside (1), together with five known compounds (2–6), were isolated from the leaves ofMicrosorium fortunei. Their structures were determined by spectroscopic techniques, especially 2D NMR and MS data analyses. All of these compounds are phenolic glycosides and were isolated from this plant for the first time. In addition, compound1showed moderate inhibitory activity against α-glucosidase with IC50value at 0.111 ± 0.061 mg/mL.
