A new triterpenoid, squasapogenol (S-11), was isolated from the hydrolytic products of dilute ethanol (10%) extract of the roots of Glycyrrhiza squamulosa Franch, along with four known triterpenoids. The structure of S-11 was elucidated as olean-11,13(18)-diene-3 beta, 22 beta-diol on the basis of chemical and spectroscopic data. The four known compounds were identified as betulinic acid(S-8), methyl ester of macedonic acid(S-9), soyasapogenol B (S-10) and olean-13(18)-ene-22 alpha-Cl-3 beta, 24-diol(S-12).
从光果甘草根的稀乙醇（10%）提取物的水解产物中分离出一种新的三萜类化合物——光果甘草醇（S-11），同时还分离出四种已知的三萜类化合物。根据化学和光谱数据，S-11的结构被鉴定为齐墩果-11,13(18)-二烯-3β,22β-二醇。四种已知化合物分别被鉴定为桦木酸（S-8）、马其顿酸甲酯（S-9）、大豆皂醇B（S-10）和齐墩果-13(18)-烯-22α-Cl-3β,24-二醇（S-12）。
