Polyhydroxylated phragmalins from the fruit of a Chinese mangrove, Xylocarpus granatum

Three new polyhydroxylated phragmalins, named xyloccensins Y, Z(1), and Z(2) (1-3), were isolated from the fruit of a Chinese mangrove, Xylocarpus granatum, together with eight known compounds. The structures of these compounds were established on the basis of spectroscopic data and chemical methods.
