Ethnopharmacological relevance: Frankincense oil and water extracts (FOE, FWE) have long been used for external treatment of inflammation and pain. The present study was conducted to identify the active ingredients responsible for the anti-inflammatory and analgesic effects and to determine the underlying mechanisms.Materials and methods: The compositions of FOE and FWE were identified and compared by GC-MS. The anti-inflammatory and analgesic activities of the two extracts and their possible active ingredients (alpha-pinene, linalool, and 1-octanol) were evaluated and compared in a xylene-induced ear edema model and a formalin-inflamed hind paw model. Inflammatory infiltrates and cyclooxygenase-2 (COX-2) expression in hind paw skin were investigated by histological staining.Results: The contents of alpha-pinene, linalool, and 1-octanol in FOE were much higher than those in FWE. Mice treated with FOE exhibited greater and faster lessening of swelling and pain than mice treated with FWE. The combination of the three components had more potent pharmacological effects on hind paw inflammation and COX-2 overexpression than the three components used alone.Conclusions: These findings suggest that topical application of FOE or its active ingredients (including alpha-pinene, linalool, and 1-octanol) exhibit significantly anti-inflammatory and analgesic effects through inhibiting nociceptive stimulus-induced inflammatory infiltrates and COX-2 overexpression.
