Sesquiterpenoids of Coniogramme maxima.[Pubmed:
22792795]
METHODS AND RESULTS:
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).
CONCLUSIONS:
The above 15 compounds are separated from C. maxima for the first time, including 9 compounds being first separated from genus Coniogramme.
