Abstract
Two new triterpenoids, namely 24-methylene-5,24-dien-19(10→9)-abeo-8α,9β,10α-eupha-3β-ol (1) and 24-methyl-5,23-dien-19(10→9)-abeo-8α,9β,10α-eupha-3β-ol (2) were isolated from the stems of Euphorbia royleana, together with three known analogs. The structures of the new compounds were elucidated by extensive 1H NMR,13C NMR, HSQC, HMBC, 1H-1H COSY, ROESY and HR-MS spectroscopic analyses.
