Introduction In vivo models of inflammation are definitely the best tools to study the biological role, because no other approach will allow the simultaneous investigation of cells and mediators that interact during the inflammatory process. Several reports in the literature have shown the efficacy of a, b-amyrin, the main component of the resin plant of the genus Protium in studies with in vit...

Tipuana tipu (Benth.) Kuntze is a tree from the leguminosae family (Papilionoideae) indigenous in Argentina and extensively used in urbanism, mainly in Southern Brazil. The epicuticular waxes of leaves and branch, and flower surface were studied by high temperature high resolution gas chromatography. Several compounds were characterized, among which the aliphatic alcohols were predominant in br...

A new glyceryl derivative (Glyceryl-1-hexacosanoate) and a flavone derivative (methyletherapigenin) were isolated from the stem bark extract of Piptadenia africana, a western Cameroonian plant species. Common terpenes like sitosterol, beta-amyrin and eicosane were also isolated. These compounds were identified using physical and spectroscopic methods including mp, IR, (1)H and (13)C-NMR, DEPT, ...

Bruguiera gymnorrhiza is widely distributed around the world, being found in tropical south and east Africa, southeastern Asia, Micronesia, Polynesia, Australia and Ryuku Islands. The bark is used as an abortifacient and for treating burns in the Solomon Islands and is used for malaria and diarrhea in Cambodia and in Indonesia and China respectively, and cure fish poisoning (Marshall Islands). ...

Antiproliferative action of different pentacyclic triterpenes has repeatedly been reported, and some lipoxygenase inhibitors have been shown to induce cell death in various cell systems. Acetyl-11-keto-b-boswellic acid (AKBA) is a pentacyclic triterpene that inhibits 5-lipoxygenase in a selective, enzymedirected, nonredox, and noncompetitive manner. To investigate a possible effect of AKBA on l...

the present investigation aims at assessing the hepatoprotective effect of triterpene fraction isolated from the stem bark of wrightia tinctoria (containing lupeol, b -amyrin and b -sitosterol) on ccl 4 -induced hepatotoxicity in the rat. ccl 4 (1.5 mg/kg, i.p) is a potent hepatotoxic agent which causes peroxidative degeneration of membrane lipids with the potential outcome of fatty degeneratio...
