This review article covers the present knowledge on the chemistry and biological activities of Piper aduncurn and its synonyms P. angustifoliurn and P. elongaturn. More than 50 compounds have been isolated from these species, which can be grouped as chromenes, phenylpropanoids, benzoic acid derivatives and flavonoids. The biological activities of the crude extracts, and the compounds isolated from them, are discussed.

OBJECTIVE: The gastric protective abilities of dried sap and alkaloid fraction of Croton palanostigma and sucralfate against ethanol-induced necrosis was compared by means of standard experimental rat model. Subchronic toxicity was determined. MATERIAL AND METHODS: A pretreatment with either saline solution, dried sap of C. palanostigma 120 mg/kg, alkaloid fraction of C. palanostigma 20 mg/kg, 35 mg/kg y 50 mg/kg or sucralfate was given to 60 rats. Intragastric administration of 2 mL of 100% ethanol was accomplished one hour later. A gastrectomy was perfomed four hours later followed by macroscopic and histological evaluation of the gastric lesions. Subchronic toxicity was determined with doses of 0,12, 0,40 and 1,20 mL/kg of sap for a 30-day period with biochemical and histopathologic study of the organs. RESULTS: Pretreatment with dried sap and alkaloid fractions of C. palanostigma and...

Se evaluaron in vitro extractos de siete plantas medicinales utilizadas específicamente contra la leishmaniasis cutánea en la región de Madre de Dios, en el Perú, contra las formas de promastigotes y amastigotes axénicos de la Leishmania amazonensis. Una de ellas mostró interesantes actividades leishmanicidas (IC50 = 5g/ml en amastigotes). El aislamiento bioguiado del extracto eólico de la corteza del tallo de Himatanthus sucuuba (Spruce ex Mull. Arg.) Woodson (Apocynaceae) proporcionó los iridoides espirolactona isoplumericina y plumericina. Esta última mostró una reducción de la infección de los macrófagos similar a la del medicamento de referencia Amphotericin B (IC50 = 0,9 y 1M, respectivamente). Estos hallazgos validan el uso tradicional de Himatanthus sucuuba en el tratamiento de la leishmaniasis cutánea (Uta) en el Perú
