Cycloneolitsin, a cyclopropanoid triterpene ether with a novel side-chain

Abstract

From the leaves of Neolitsea dealbata R.Br. Merr. were isolated taraxerol and sitosterol together with a new triterpene, ?cycloneolitsin?, C₃₃H₅₆O. By converting both it and cycloartenol into a common derivative, the structure was established as 3β-methoxy-24,24- dimethyl-9,19-cyclolanost-25-ene (Ib).
