The fronds of Scypholepia hookeriana J. SM. (Microlepia hookeriana (WALL.) PRESL) afforded four oligoglycosides of a new ent-pimarane-type diterpene, which were named hookerosides A (I), B (II), C (III) and D (IV). The structures were elucidated by means of chemical reactions and spectroscopic methods to be 3α-[O-(3-O-methyl)-α-L-rhamnopyranosyl-(1→2)-α-L-arabinofuranosyloxy]-12α-[(3-O-methyl)-β-D-quinovopyranosyloxy]-(I), 3α-[O-(3-O-methyl)-α-L-rhamnopyranosyl-(1→2)-α-L-arabinofuranosyloxy]-12α-[β-D-fucopyranosyloxy]-(II), 3α-[O-(3-O-methyl)-β-D-glucopyranosyl-(1→2)-α-L-arabinofuranosyloxy]-12α-[β-D-fucopyranosyloxy]-(III) and 3α-[O-β-D-fucopyranosyl-(1→3)-O-β-D-fucopyranosyl (1→2)-α-L-arabinofuranosyloxy]-12α-[β-D-fucopyranosyloxy]-(IV) ent-pimara-8 (14), 15-diene.
