Abstract
A crystalline compound, C₃₀H₄₈O₃, m.p. 275.0-278.0°C (dec.), was isolated from the bark of Arbutus menziesii (1.5%). Spectroscopic evidence suggests the presence of a hydroxyl group and an isopropenyl group in the molecule. Because of the absence of double bonds other than that of the isopropenyl group, the molecule is thought to be pentacyclic. The nature of the remaining two oxygen functions and the exact nature of the skeleton of the molecule remain to be investigated. Spectral studies on the acetylation and the lithium aluminum hydride products are also reported
