Cytotoxic Alkaloids from the Stem of Xylopia laevigata.
Xylopia laevigata (Annonaceae), known locally as "meiú" or "pindaíba", is widely used in folk medicine in Northeastern Brazil. In the present work, we performed phytochemical analyses of the stem of X. laevigata, which led to the isolation of 19 alkaloids: (-)-roemerine, (+)-anonaine, lanuginosine, (+)-glaucine, (+)-xylopine, oxoglaucine, (+)-norglaucine, asimilobine, (-)-xylopinine, (+)-norpur...

متن کاملCytotoxic alkaloids from Houttuynia cordata.
Six bioactive alkaloids, aristolactam B(1), piperolactam A(2), aristolactam A(3), norcepharadione B(4), cepharadione B(5) and splendidine(6) were isolated by bioactivity-guided fractionation of a methanolic extract of the aerial part of Houttuynia cordata. Several of them exhibited significant cytotoxicity against five human tumor cell lines (A-549, SK-OV-3, SK-MEL-2, XF-498 and HCT-15) in vitro.
متن کاملEvaluation of the Anti-Inflammatory and Antinociceptive Effects of the Essential Oil from Leaves of Xylopia laevigata in Experimental Models
Xylopia laevigata (Annonaceae) is a medicinal plant used in folk medicine to treat pain and inflammation. Thus, we investigated the possible antioxidant, antinociceptive, and anti-inflammatory effects of X. laevigata leaf essential oil (EOX) in animal models. Our EOX sample showed the presence of γ-muurolene (17.78%), δ-cadinene (12.23%), bicyclogermacrene (7.77%), and α-copaene (7.17%) as main...
متن کاملTHE CYTOTOXIC EFFEC T OF CHELIDONIUM ALKALOIDS ON CELLS ISOLATED FROM ADULT RAT LIVER
Alkaloids of the aerial parts of chelidonium were extracted in the salt form, and their aqueous solutions were prepared in different concentrations. Rat hepatocytes were obtained by liver perfusion. The alkaloidal solutions were added to suspensions of hepatocytes in petri dishes and the mixtures were incubated. Two types of controls have been used in one type. no alkaloidal extract was ad...
