New antitrypanosomal tetranotriterpenoids from Azadirachta indica.
Organic extracts of the leaves of Azadirachta indica A. Juss. yielded ten antitrypanosomal terpenoids. Three of these (1-3), are novel and are derivatives of nimbolide and nimbin. They were extracted from chloroform fraction of methanol extract. These compounds were found to exhibit strong antitrypanosomal activities against Trypanosoma brucei rhodesiense with MIC values ranging of 6.9, 15.6 an...
متن کاملNew Triterpenoids from Peucedanum ruthenicum
From hexanic extract of aerial parts of Peucedanum ruthenicum M. Bieb (Apiaceae) collected from Mazandaran province of Iran, four triterpenoids namely taraxasterol, y-taraxasterol, poriferasterol and b-sitosterol have been isolated by column chromatography, thin layer chromatography, and crystallization. Their structures were elucidated by spectroscopic methods (UV, IR, MS, 1H and 13C-N...

The microscopic and macroscopic characters of the leaves, physical constant values, behavior on treatment with different chemical reagents, fluorescence characters under ultra violet light after treatment with different chemical reagents of the powdered leaves of Azadirachta indica A. Juss (Family-Meliaceae) were studies to fix some pharmacognostical parameters.
متن کاملPhotooxygenation of Nimonol, a Tetranortriterpenoid from Azadirachta indica. A. Juss
Nimonol (1), a tetranortriterpenoid isolated from the leaves of Azadirachta indica A. Juss (Meliaceae), upon photolysis undergoes both Diels-Alder and ene reactions with singlet oxygen at different sites leading to 14,15,20,21-diepoxy-23-nimonolactone (3), along with nimonolide (4), which have been well-characterised. The novelty of the reported reactions lies in hitherto unreported formation o...
