Abstract : Ethnopharmacological relevance: Morinda citrifolia L. (Noni) is a medicinal plant used in Polynesia for many properties such as anti-inflammatory, anti-diabetic and antineoplastic effects. Recent studies showed that noni juice have anti-oxidant and acute anti-inflammatory activities likely due to polyphenols, iridoids and vitamin C content. The present study was undertaken to evaluate chronic anti-inflammatory and spasmolytic effects of noni juice. Materials and methods: Therefore, we evaluated the effect of oral or intraperitoneal administrations of noni juice in vivo on the lung inflammation in ovalbumin (OVA) sensitized Brown Norway rat (with prednisolone 10 mg/kg intraperitoneously as reference compound) and the ex vivo effect of noni juice on BaCl2 (calcium signal) or methacholine (cholinergic signal) induced spasms in jejunum segments. Results: We found that noni juice (intraperitoneously 2.17 mL/kg and orally 4.55 mL/kg) reduced the inflammation in OVA-sensitized Brown Norway rat with regard to the decreased number of inflammatory cells in lung (macrophages minus 20–26%, lymphocytes minus 58–34%, eosinophils minus 53–30%, neutrophils minus 70–28% respectively). Noni juice demonstrated a dose-dependent NO scavenging effect up to 8.1 nmol of nitrites for 50 µL of noni juice. In addition noni juice inhibited (up to 90%) calcium and cholinergic induced spasms on the jejunum segments model with a rightward shift of the concentration response curve. Conclusion: We describe for the first time that noni juice demonstrate (1) a chronic anti-inflammatory activity on sensitized lungs along with (2) a spasmolytic effect integrating a calcium channel blocker activity component.
