Four new triterpenoids, named Toosendansins A-D (1-4), along with nine known ones (5-13) were isolated from the fruits of Melia toosendan Sieb. et Zucc. Their structures were established on the basis of spectroscopic data. The isolation of compounds 1-12 were reported for the first time from this plant. All compounds were analyzed for the anti-Tobacco Mosaic Virus (TMV) activity and protective effect on H2O2-induced damage of SH-SY5Y cells. Compound 7 showed evident anti-TMV activity. Compounds 2 and 9 exhibited modest protection against H2O2-induced damage of SH-SY5Y cells.
