To study sesquiterpenoids of Coniogramme maxima. Chemical constituents were separated by chromatography and their structures were identified according to physicochemical property and spectrum data. Fifteen compounds were separated by chromatography technique. Their structures were determined by spectral data, including 10 sesquiterpenoids as (3S)-pteroside D (1), epi-pterosin L (2), pterosin D (3), onitin (4), pterosin Z (5), onitisin (6), onitisin-glucopyranoside (7), onitin-15-O-beta-D-glucopyranoside (8), (2S,3R)-pterosin-L-2'-O-beta-D-glucopyranoside (9) and (3R)-peterosin D-3-O-beta-D-glucopyranoside (10). The other compounds were uracil (11), 3,4-dihydroxybenzaldehyde (12), 5-hydroxymethyl-2-furancarboxaldehyde (13), beta-sitosterol (14) and daucosterol (15). The above 15 compounds are separated from C. maxima for the first time, including 9 compounds being first separated from genus Coniogramme.
