Four new acetophenone di-C-glycosides, pteleifolols A–D (14) and a new dimeric benzopyran, pteleifolol E (5), were isolated from the leaves of Melicope pteleifolia. Seven known compounds, including 2,4,6-trihydroxyacetophenone-3,5-di-C-glucopyranoside (6), were also isolated. Structures of the new compounds (15) were established by using spectroscopic and spectrometric techniques, including 1D and 2D nuclear magnetic resonance (NMR), UV, and high-resolution electrospray ionization mass spectrometry (HR-ESI–MS) data. Pteleifolols A–D (14) were E-p-coumaroyl, Z-p-coumaroyl, E-feruloyl, and benzoyl esters of 6, respectively. Pteleifolol E (5) was a dichromene dimerized through a C2 unit.
