Objective To study the chemical constituents from the aerial part of Euphorbia sikkimensis. Methods The chemical constituents were isolated and purified through various column chromatographies. The structures of all the isolated compounds were identified by combination of spectroscopic methods (MS, 1H, 13C NMR) with the literature data. Results Sixteen compounds were isolated from the aerial part of E. sikkimensis. They were 9-epi-blumenol C (1), blumenol A (2), 4-hydroxy-2,3-dimethyl-2-nonen-4-olide (3), caulilide I (4), 6-methoxy-7,8-methylenedioxycoumarin (5), herniarin (6), ingenol (7), sakuranetin (8), naringenin (9), luteolin (10), taraxerone (11), glutinone (12), phytol (13), 9,12,15-linoleic acid (14), 9,12-linoleic acid (15), and α-monpalmitin (16). Conclusion All the isolated compounds, except compounds 9 and 14, are isolated from this plant for the first time.
