Outline
Eleven compounds were isolated from the twigs and leaves of Xylopia vielana Pierre by various chromatographic techniques such as silica gel, ODS and the semi-preparative HPLC. Their chemical structures were identified by HR-ESI-MS, NMR, ECD and other spectroscopic methods as vielana A (1), vielana B (2), vielana C (3), 10-oxo-isodauc-3-en-15-al (4), 1α-hydroxyisodauc-4-en-15-al (5), mokko lactone (6), 11β,13-dihydrocostunolide (7), eurylosesquiterpenol E (8), epi-α-cadinol (9), mustakone (10), 7-epi-amiteo (11). Among them, compounds 1-3 were new compounds, and the rest compounds were isolated from this plant for the first time. Compounds 1 and 2 increased the transcriptional activity of the farnesoid X receptor (FXR) downstream target gene BSEP promoter, indicating that they have potential of FXR activation.
