Two new compounds from the fruits of Buddleja lindleyana with neuroprotective effect

J Asian Nat Prod Res. 2012;14(4):342-7. doi: 10.1080/10286020.2011.653783.

Abstract

Two new triterpenoid glycosides, mimengosides H (1) and I (2), were isolated from the fruits of Buddleja lindleyana Fort. Their structures were determined by extensive spectroscopic methods. Neuroprotective effects of these isolates against 1-methyl-4-phenylpyridinium ion-induced neurotoxicity in PC12 cells were evaluated. Pretreatment with compound 1 had potential protective effect in a concentration range from 0.1 to 1 μmol l⁻¹.
