A systematic study of the chemical constituents of the n-butanol extraction of Ephedra intermedia (E. intermedia) was carried out and 15 compounds were isolated using various column chromatography combinations with modern wave spectroscopy. Their structures were identified as (7R, 8S, 7′R, 8′S, 7″R, 8″S)-ephnan A (1), 4-methoxy garcimangosone D (2), garcimangosone D (3), (+)-syringaresinol (4), (+)-syringaresinol-O-β-D-glucopyranoside (5), methyl benzoate-4-β-glucoside (6), 3-methoxy-4-O-β-D-glucopyranosyloxy-benzoic acid methyl ester (7), methyl syringate 4-O-β-D-glucopyranoside (8), trans-4-O-β-D-glucopyranosyl ferulic acid (9), 3, 5-dimethoxy-4-O-β-D-glucopyranosyl-cinnamic acid (10), raspberry ketone O-β-D-glucopyranoside (11), E-melilotoside (12), β-D-glucopyranosyl-benzoate (13), 3, 4-dihydroxybenzoic acid 3-O-β-D-glucoside (14), 3, 5-dihydroxy-4-O-β-D-glucopyranosyl acetophenone (15). Compounds 1 and 2 were new compounds, compounds 6-9 and 13-15 were isolated from Ephedra for the first time. Compounds 7, 11-14 exhibited potential anti-pneumonia activity.
