Abstract
Two new hydrolyzable tannins, nobotanin S (1) and melastoflorin A (2), were isolated from the leaves of Monochaetum multiflorum, and their structures were characterized as tetrameric and pentameric ellagitannins based on deta iled NMR analyses using 2D-NMR techniques and chemical evidence. Melastoflo rin A (pentamer) was notably the biggest molecule among numerous hydrolyzab le tannins.
