A phytochemical investigation on the 70% EtOH extract from the dry fronds of Diplopterygium rufopilosum afforded two new labdane-type diterpene glycosides, (3β,13S)-3-O-β-d-glucopyranosyl-13-O-α-l-rhamnopyranosyl-labda-8(17),14-diene (1) and (3β,13S)-3-O-α-l-rhamnopyranosyl-13-O-[6-O-acetyl-β-d-glucopyranosyl-(1 → 4)-2-O-acetyl-α-l-rhamnopyranosyl]-labda-8(17),14-diene (2). Their structures were determined on the basis of chemical method and spectroscopic analyses, including 1D and 2D NMR (COSY, HMQC, HMBC, and NOESY) and HR-ESI-MS analyses.
对粗毛双扇蕨干燥叶状体的70%乙醇提取物进行植物化学研究，得到了两种新的半日花烷型二萜糖苷，(3β,13S)-3-O-β-D-吡喃葡萄糖基-13-O-α-L-吡喃鼠李糖基-半日花-8(17),14-二烯（1）和(3β,13S)-3-O-α-L-吡喃鼠李糖基-13-O-[6-O-乙酰基-β-D-吡喃葡萄糖基-(1→4)-2-O-乙酰基-α-L-吡喃鼠李糖基]-半日花-8(17),14-二烯（2）。通过化学方法和光谱分析，包括一维和二维核磁共振（COSY、HMQC、HMBC和NOESY）以及高分辨电喷雾电离质谱分析确定了它们的结构。
