Further C-15-acyl phragmalin derivatives from Chukrasia tabularis A. Juss.

Sixteen phragmalins with three types of enolic acyl substituents at C-15 were isolated from the seeds of Chukrasia tabularis A. Juss. One of these (compound 1) had its structure determined by NMR and X-ray diffraction analysis, while the others were determined via NMR, HR-MS, and CD spectra.
