Acronyols A and B, new anti-inflammatory prenylated phloroglucinols from the fruits of Acronychia crassipetala

Abstract

Two new phloroglucinols, acronyols A (1) and B (2) along with the four known (3–6) pholoroglucinols were identified following anti-inflammatory activity guided fractionation from the fruits of Acronychia crassipetala (family Rutaceae). The pholoroglucinols (1–6) were evaluated for their inhibitory effects on NO production and downregulation of TNF-α in RAW 264.7 macrophage cell lines.
