Diabetes mellitus is the most common endocrine disorder that impairs glucose homeostasis resulting in severe diabetic complications including retinopathy, angiopathy, nephropathy, and neuropathy causing neurological disorders due to perturbation in utilization of glucose. Hypoglycemic activity was detected in aqueous extract of Passiflora ligularis, a traditionally used medicinal plant, using s...

Ten Linnaean names of Pedicularis (Orobanchaceae) are lectotypified: P. comosa, P. flammea, P. hirsuta, P. incarnata, P. lapponica, P. resupinata, P. rostrata, P. tristis, P. tuberosa and P. verticillata. Lectotypes are designated from the Linnaean herbarium at LINN. The type choices made here maintain the present usage of the corresponding Linnaean names for ten Pedicularis species.

Tendrils can be found in different plant species. In legumes such as pea, tendrils are modified leaves produced by the vegetative meristem but in the grape vine, a same meristem is used to either form a tendril or an inflorescence. Passiflora species originated in ecosystems in which there is dense vegetation and competition for light. Thus climbing on other plants in order to reach regions wit...

Plants used in traditional medicine are rich sources of hemolysins and cytolysins, which are potential bactericidal and anticancer drugs. The present study demonstrates for the first time the presence of a hemolysin in the leaves of Passiflora quadrangularis L. This hemolysin is heat stable, resistant to trypsin treatment, has the capacity to froth, and acts very rapidly. The hemolysin activity...

Background Leaf shape among Passiflora species is spectacularly diverse. Underlying this diversity in leaf shape are profound changes in the patterning of the primary vasculature and laminar outgrowth. Each of these aspects of leaf morphology-vasculature and blade-provides different insights into leaf patterning. Results Here, we morphometrically analyze >3300 leaves from 40 different Passifl...

DNA barcoding is a technique for discriminating and identifying species using short, variable, and standardized DNA regions. Here, we tested for the first time the performance of plastid and nuclear regions as DNA barcodes in Passiflora. This genus is a largely variable, with more than 900 species of high ecological, commercial, and ornamental importance. We analyzed 1034 accessions of 222 spec...

Cinco glicosídeos foram isolados a partir das folhas de P. alata. Após extensivas análises espectroscópicas, as estruturas 1-5 foram identificadas como sendo o 3-O-β-D-glicopiranosilestigmasterol (1), o ácido 3-O-β-D-glicopiranosil-oleanólico (2), o ácido 3-O-β-D-glicopiranosil(1→3)-β-D-glicopiranosil-oleanólico (3), o ácido 3-O-β-Dglicopiranosil-(1→2)-β-D-glicopiranosiloleanólico (4) e 9,19-ci...

Summa Phytopathol., Botucatu, v. 40, n. 2, p. 134-140, 2014 The purple passionfruit plant, Passiflora edulis Sims, ranks second in fruit exportation in Colombia, and its main destination is the European market. However, its production is affected by several diseases, including fusariosis. This paper presents the histopathological features of different tissues affected by the pathogens Fusarium ...
