Our objective was to study the activity of Ludwigia octovalvis hydro alcoholic extract in rats made experimentally hypertensive by a hypersodic diet. After 21 days this diet, systolic and diastolic blood pressure these animals increases 200.1 ± 1.5 / 155.6 mm Hg, respectively. Administered orally, reduces high pressure. The control group returned its normal value (113.2 1.2/76.3 1) Hg after 24 ...

Two new genera are described for three species in the “red” group of North American eumenine wasps from genus Odynerus Latreille, 1802: Bohartodynerus Fateryga, gen. n. O. margaretellus Rohwer, 1915 (type species) and cinnabarinus Bohart, 1939, Parkerodynerus erythrogaster 1939). comb. is newly recorded Nevada New Mexico B. California, Mexico, Utah, Wyoming.

El cambio de color las flores y la producción asexual semillas (apomixis), son dos fenómenos poco estudiados en angiospermas. En este trabajo estudiamos ambos Fuchsia thymifolia, una especie ginodioica donde coexisten plantas hembra que únicamente producen femeninas con hermafroditas, poblaciones naturales Michoacán. Para estudiar el flores, se marcaron botones florales los cuales fueron censad...

UNLABELLED PREMISE OF THE STUDY We developed 24 nuclear microsatellite primers from an enriched genomic library for the Pacific coastal dune endemic Camissoniopsis cheiranthifolia to study the consequences of mating system differentiation, the genetics of species' range limits, and hybridization with its closest sister taxon, C. bistorta. • METHODS AND RESULTS Twenty-four primer pairs were...

Two new flavonol glycosides, myricetin 4'-O-alpha-L-rhamnopyranoside (1) and quercetin 3'-O-alpha-L-rhamnopyranoside (2), together with a novel biflavonol compound, speciin (3), as well as eleven phenolic metabolites, namely myricitrin (4), europetin 3-O-alpha-L-(1)C(4)-rhamnopyranoside (5), quercitrin (6), hyperin (7), rhamnetin 3-O-beta-galacto-pyranoside (8), caffeic acid (9), caffeic acid m...
