Aim of study: The fruit of Melia toosendan Sieb. et Zucc. (MTF) is a traditional Chinese herbal medicine in the treatment of stomachache and many acute or chronic inflammations, as well as ascariasis. This paper aimed to investigate the anti-inflammatory and analgesic activities of the MTF extract and two main limonoid-type triterpencids isolated from MTF.
Materials and methods: The ethanolic extract of MTF and two limonoids, isotoosendanin (1) and 1-O-tigloyl-1-O-debenzoylohchinal (2) were evaluated for their anti-inflammatory and analgesic activities. Acetic acid-induced vascular permeability and lambda-carrageenan-induced hind paw edema tests in mice were used to investigate anti-inflammatory activity; and acetic acid-induced writhing and hot-plate tests in mice were used to determine analgesic effect.
Results: Both the ethanolic extract and two limonoids displayed significant anti-inflammatory effects. Although the ethanolic extract showed remarkable analgesic effects in both writhing and hot-plate tests, the two limonoids had analgesic effects just in writhing test.
Conclusion: The results suggested that the ethanolic extract of MTF had obvious anti-inflammatory and analgesic activities, and the two limonoids were the active constituents contributing to the anti-inflammatory and analgesic effects of MTF.
