title: Platanionosides D-J: megastigmane glycosides from the leaves of Alangium platanifolium (Sieb. et Zucc.) Harms var. platanifolium Sieb. et Zucc.
abstract: From the leaves of Alangium paltanifolium var. platanifolium, collected in Fukuoka Prefecture, twelve further megastigmane glycosides were isolated. Seven of them, named platanionosides D-J (1-7), were found to be new compounds. Their structures were elucidated from spectroscopic evidence and their absolute structures were determined from beta-D-glucosylation-induced shift trends of 13C-NMR and by application of a modified Mosher's method.
