Abstract
In the course of our ongoing phytochemical investigation on the n-butanol extract of the fruits of Tetradium ruticarpum (Rutaceae), three new compounds, ruticarpsides A–C (1–3), were obtained and their structures were elucidated by a comprehensive analysis of NMR and MS data. Compound 3 showed a weak inhibition effect on nitric oxide production in BV-2 microglial cells stimulated with lipopolysaccharide.
