Abstract
The new compound identified as 16α23αdihydroxy3β28β30αtriacetoxyolean12ene named birsonimadiol BIR was isolated from Byrsonima crassifolia seeds using activityguided fractionation and structural elucidation was achieved based on extensive analysis of spectroscopic data Effects of BIR on acute and chronic phases of inflamation were studied in edema induced using formaldehyde 12Otetradecanoylphorbolacetate TPAinduced ear edema meloperoxidase activity and histamine carrageenan cotton pellet granuloma and adjuvantinduced arthritis Antiinflammatory activities of BIR were indicated based on reduction of edema levels induced in models of inflammation Antiinflammatory activities were also investigated in murine macrophage RAW2647 cells BIR suppressed production of nitric oxide NO and prostaglandin E2 PGE2 decreased gene expression of cyclooxygenase2 COX2 inhibited tumor necrosis factor TNFα and protein secretion of interleukin IL6 Triterpene was an effective topical antiinflammatory agent in experimental models of acute and chronic dermatitis and can be used in inflammatory disorders
