[Studies on the triterpenoids from roots of Glycyrrhiza squamulosa Franch].
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).
