Two new natural compounds, (1,2)-2-(6-hydroxyhexylidene)cyclopropyl--D-glucopyranoside () and (6)-6-[(2)-2-(-D-glucopyranosyloxy)cyclopropylidene]hexanoic acid (), glucosides of a very rare methylidenecyclopropane alcohol, as well as two known glycosides of phenolic acids, namely 4---D-glucopyranosylcaffeic acid () and ()-4---D-glucopyranosylcoumaric acid (), and methyl -fructofuranoside () were isolated for the first time from the rhizomes of the tree fern C.Presl. The structures were elucidated on the basis of detailed spectroscopic data analysis, and the structure of 1 was additionally confirmed by X-ray crystal-structure analysis.
从树蕨C.Presl的根茎中首次分离出两种新的天然化合物，即（1,2）-2-（6-羟基亚己基）环丙基--D-吡喃葡萄糖苷（）和（6）-6-[(2)-2-(-D-吡喃葡萄糖氧基)环亚丙基]己酸（），一种非常罕见的亚甲基环丙烷醇的糖苷，以及两种已知的酚酸糖苷，即4---D-吡喃葡萄糖基咖啡酸（）和（）-4---D-吡喃葡萄糖基香豆酸（），还有甲基 -呋喃果糖苷（）。通过详细的光谱数据分析阐明了其结构，并且1的结构通过X射线晶体结构分析得到了进一步确认。
