Abstract
White bird-lime was purified with ether from which 48% of purified bird-lime was obtained. Its hydrolysis yielded 42.8% of fatty acids, 41.4% of crystalline unsaponifiable matter, and 4.3% of non-crystalline unsaponifiable matter. Acetylation of the crystalline unsaponifiable matter, followed by recrystallization from ethyl acetate yielded a new triterpene alcohol in 1.61% yield, designated as ilexol, of m.p. 205-206°, [α]D28: -16.81°(CHCl3), which gives an acetate of m.p. 282-283°, [α]D28: +22.29°(CHCl3), and a benzoate of m.p. 242-243°. α-Amyrin and lupeol were detected in the residue, with a larger amount of α-amyrin. No evidence was obtained for the presence of β-amyrin.
