[Studies on chemical constituents from fruits of Forsythia suspense].

Twenty-four compounds in the fruits of Forsythia suspensa were isolated and purified by column chromatography and preparative TLC. On the basis of comprehensive spectroscopic methods including IR, ESI-MS/MS, 1D and 2D NMR, these compounds were identified as ten ceremides (1-10), six triterpenes (11-16), one steroids (17), three flavonoids (18-20), two C6-C2 alcohols (21-22) and two lignans (23-24). Compounds 1-10 were reported from F. suspense for the first time, among which 1, 2, 4 and 5 were new ones.
