A new dammarane triterpenoid glycoside named cyclocarioside J (1) and other three known triterpenoid glycosides were isolated from the leaves of Cyclocarya paliurus. Based on ESI-MS, HR-ESI-MS, (1)H NMR, (13)C NMR, and 2D NMR techniques including (1)H-(1)H COSY, HMBC, HMQC, and NOESY correlations, the structure of cyclocarioside J was elucidated as (20S,24R)-epoxydammarane 3β,12β,25-trihydroxy-12-O-β-d-quinovopyranosyl-3-O-α-l-arabinopyranoside.
从青钱柳叶片中分离得到了一种名为环青钱柳苷J（1）的新达玛烷三萜糖苷以及其他三种已知的三萜糖苷。基于电喷雾电离质谱（ESI-MS）、高分辨电喷雾电离质谱（HR-ESI-MS）、核磁共振氢谱（¹H NMR）、核磁共振碳谱（¹³C NMR）以及二维核磁共振技术，包括¹H-¹H 同核化学位移相关谱（¹H-¹H COSY）、异核多键相关谱（HMBC）、异核单量子相关谱（HMQC）和核Overhauser效应相关谱（NOESY），环青钱柳苷J的结构被鉴定为（20S，24R）-环氧达玛烷-3β，12β，25-三羟基-12-O-β-D-奎诺吡喃糖基-3-O-α-L-阿拉伯吡喃糖苷。
