A new dihydrofurocoumarin from the fruits of Pandanus tectorius Parkinson ex Du Roi.

From the fruit of Pandanus tectorius Parkinson ex Du Roi, one new dihydrofurocoumarin, named pandanusin A (1) and 15 known compounds, including one furanocoumarin (2), two coumarins (3, 4), four lignans (5-8), one neolignan (9), two flavonoids (10, 11), three phenolics (12-14), one monoglyceride (15) and one monosaccharide (16) were isolated by various chromatography methods. Among them, compounds (3-5) were obtained from the Pandanus genus for the first time and compounds (9-14, 16) were reported from this species for the first time. Their structures were elucidated by HR-ESI-MS, NMR 1D and 2D experiments and comparison with previous reported data.
