一种新的γ-内酯衍生物，名为达瓦利内酯（4）和（+/-）-圣草酚的7-O-β-D-葡糖苷酸（5a），与咖啡酸（1）、4-O-β-D-吡喃葡萄糖基咖啡酸（2）和4-O-β-D-吡喃葡萄糖基-p-香豆酸（3）一起从达瓦利摩尔中分离得到。新化合物的结构通过化学和光谱方法确定，包括二维核磁共振（2D NMR）技术，特别是H-1检测的杂原子多键多量子相干和长程C-H J分辨2D NMR技术。
A new gamma-lactone derivative named davallialactone (4) and the 7-O-beta-D-glucuronide of (+/-)-eriodictyol (5a) have been isolated from Davallia mariesii MOORE along with caffeic acid (1), 4-O-beta-D-glucopyranosylcaffeic acid (2) and 4-O-beta-D-glucopyranosyl-p-coumaric acid (3). The structures of the new compounds were determined by chemical and spectroscopic methods including two-dimensional nuclear magnetic resonance (2D NMR) techniques, especially H-1-detected heteronuclear multiple-bond multiple-quantum coherence and long-range C-H J-resolved 2D NMR techniques.
