xylopia rubescens/leukemia

Two new diterpenes were isolated from stems and leaves of Xylopia langsdorffiana, ent-atisane-7alpha,16alpha-diol (xylodiol) and ent-7alpha-acetoxytrachyloban-18-oic acid (trachylobane), along with the known 8(17),12E,14-labdatrien-18-oic acid (labdane). We investigated their antitumour effects on

The cytotoxicity of extracts obtained from plants occurring in the Amazon and Atlantic rain forests against NCI-H460, KM-12, SF-268 and RPMI-8226 cancer cell lines was investigated. Expressive activity was observed in the extracts of Toulicia cf. pulvinata, Ampirrhox sp., Macoubea sprucei,

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,

BACKGROUND Xylopia aethiopica, a plant found throughout West Africa, has both nutritional and medicinal uses. The present study aims to characterize the effects of extracts of this plant on cancer cells. RESULTS We report that X. aethiopica extract prepared with 70% ethanol has antiproliferative

BACKGROUND Multidrug resistance (MDR) in cancer represent a major hurdle in chemotherapy. Previously, the methanol extract of the medicinal spice Xylopia aethiopica displayed considerable cytotoxicity against multidrug resistant (MDR) cancer cell lines. METHODS The present study was designed to

BACKGROUND Echinops giganteus, Imperata cylindrica, Piper capense and Xylopia aethiopica are four medicinal spices used in Cameroon to treat cancers. OBJECTIVE The above plants previously displayed cytotoxicity against leukemia CCRF-CEM and CEM/ADR5000 cell lines as well as human pancreatic

BACKGROUND The genus Xylopia L. (Annonaceae) includes aromatic plants that have both nutritional and medicinal uses. Essential oils of Xylopia species have antitumour effects. However, the efficacy of the essential oil from the fruit of Xylopia langsdorffiana St. Hil & Tul. (EOX) has not been

BACKGROUND Several medicinal plants and spices are used traditionally to treat cancers in Cameroon. OBJECTIVE Methanol extracts from thirty-four spices and plants, with related ethnobotanical use were investigated for their in vitro cytotoxicity on the human pancreatic cancer cell line MiaPaCa-2,
