Persicaside has been isolated as a new alkaloid natural compound from a methanol (EtOA)-soluble extract of Prunus persica seed. It was purified by a combination of chromatographic techniques and recrystallization. The structure of Persicaside was determined by extensive NMR experiments and mass ppectroscopic data. It inhibited nitric oxide (NO) and prostaglandin E2 (PGE2) production via suppression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2 expression in rat osteoblast sarcoma cells (ROS 17/2.8) in concentration-dependent manner whereas it spares the COX-1 enzyme activity.
