摘要: 为研究短角湿生冷水花(Pilea aquarum subsp. brevicornuta)化学成分。实验采用色谱法从中分离得到7个化合物,包括5个五环三萜、一个甾醇和一个木脂素。利用波谱学方法鉴定了它们的结构,分别鉴定为pilearbornol(1)、rubiarbonone D(2)、camarolide(3)、表齐墩果酸(4)、齐墩果酮酸(5)、5,8-epidioxy-(3β,5α,8α,22E)-ergosta-6,9(11),22-trien-3-ol(6)和桉脂素(7)。其中,化合物1和2属于乔木萜烷型(arborane)三萜,化合物1为新化合物,化合物2的绝对构型首次通过X-射线单晶衍射得到了确定。所有化合物均为首次从该植物中分离得到,这也是首次从荨麻科植物中分离得到乔木萜烷型三萜化合物。

Abstract: The study was focus on the chemical constituents of Pilea aquarum subsp. brevicornuta and seven compounds were obtained.Their structures were identified as pilearbornol (1),rubiarbonone D (2),camarolide (3),epi-oleanolic acid (4),oleanonic acid (5),5,8-epidioxy-(3β,5α,8α,22E)-ergosta-6,9(11),22-trien-3-ol (6) and eudesmin (7),respectively,by spectroscopic methods.Among them,compounds 1 and 2 belong to arborane-type triterpenoids and compound 1 is new.In addition,the absolute configuration of compound 2 was determined by X-ray crystal diffraction.All isolates were discovered from this plant for the first time and this is the first time to report arborane triterpenoids from Urticaceae family.

Key words: Pilea aquarum subsp. brevicornuta, arborane, triterpenoids, absolute configuration
