Abstract

Six new compounds, xylomexicanins K-N (1–4), granasteroid (5) and 5-methoxy-2-pentylbenzofuran-7-ol (6), along with nine known compounds were isolated from the leaves and twigs of Xylocarpus granatum. Among them, 1 was a biogenetic precursor of 1,8,9-phragmalin limonoid, and 4 represent the first example of degraded A-ring limonoid. The structures of them were elucidated on the basis of one- and two-dimensional NMR spectroscopic data (including ¹H, ¹³C-NMR, DEPT, ¹H-¹H COSY, HSQC, HMBC, and NOESY) and confirmed by high-resolution mass spectrometry.
