STUDIES ON THE TRITERPENOIDS FROM ROOTS OF GLYCYRRHIZA SQUAMULOSA FROANCH

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- 3β, 22β-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-22α-C1- 3β, 24-diol(S-12).
