Chemical constituents, antioxidant, anti-inflammatory and, antinociceptive activities of Trichilia ramalhoi

Abstract

Trichilia ramalhoi Rizz. is a species from Meliaceae family and its chemical composition and biological activities are still unknown. This work describes the chemical composition and biological activities of the organic extracts of this plant. Therefore, methanolic extract of stem barks and leaves were prepared and submitted to chromatographic procedures. Besides, T. ramalhoi extracts biological evaluation showed antioxidant, antinociceptive and, anti-inflammatory activities. Usual chromatographic procedures of the active extracts permitted to isolate methyl 5-O-caffeoylquinate, apocynin C, cinchonains Ia and Ib, besides β-sitosterol, stigmasterol and lupeol. The
