Euferol and melliferol: two novel triterpenoids from Euphorbia mellifera
Abstract
The structures and stereochemistries of two novel skeletons euferol [19(10→9)abeo-8α,9β,10α-tirucall-5-en-3β-ol] and melliferol [19(10→9)abeo-5α,8α,9β-tirucall-1 (10)-en-3β-ol], found in Euphorbia mellifera, have been established from spectral data and single crystal X-ray analyses.
