从川楝子（Melia toosendan SIEB）叶中分离得到一个新的川楝烷苷，命名为川楝苷（1）。et Zucc.（楝科）。化合物1的结构经化学和光谱鉴定为（20 R）-5α-藜芦烷-2 α，3α，16β，20-四醇2-O-β-D-吡喃葡萄糖苷。
A new pregnane glycoside, named toosendanoside (1), has been isolated from leaves of Melia toosendan SIEB. et Zucc.(Meliaceae). The structure of 1 has been assigned as (20R)-5α-pregnane-2α, 3α, 16β, 20-tetrol 2-O-β-D-glucopyranoside, based on lines of chemical and spectral evidence.
