title: Neuroprotective bibenzyl glycosides of Stemona tuberosa roots.
abstract: Three new bibenzyl glycosides characterized as stilbostemin B 3'-beta-D-glucopyranoside (1), stilbostemin H 3'-beta-D-glucopyranoside (2), and stilbostemin I 2"-beta-D-glucopyranoside (3) were isolated from the roots of Stemona tuberosa. All three bibenzyl glycosides significantly protected human neuroblastoma SH-SY5Y cells from 6-hydroxydopamine-induced neurotoxicity.
