The present study investigated the in vitro antiprotozoal activity of sixteen selected medicinal plants. Plant materials were extracted with methanol and screened in vitro against erythrocytic schizonts of Plasmodium falciparum, intracellular amastigotes of Leishmania infantum and Trypanosoma cruzi and free trypomastigotes of T. brucei. Cytotoxic activity was determined against MRC-5 cells to a...

Botanists and mycologists have long debated the potential for full myco-heterotrophy in the achlorophyllous Pyrola aphylla (Ericaceae). Here we address the ecophysiology of this putative myco-heterotroph and two other closely related green species in the tribe Pyroleae (Pyrola picta and Chimaphila umbellata). The stable isotopes of carbon and nitrogen (delta13C and delta15N) were analysed from ...

Liparis aphylla G.A.Romero & Garay was previously known only from two herbarium specimens collected in 1945 and 1977 in Ecuador and Colombia, respectively. This little-known species is hereby reported for the first time for Peru. An updated description, line illustration, color photographs and distribution map of Liparis aphylla, as well as an identification key to the Peruvian species of Lipar...

Context. Many diseases are associated with oxidative stress caused by free radicals. Objective. The present study evaluated the in vitro antioxidant and antibacterial activities of various extracts of aerial parts of Periploca aphylla and Ricinus communis. Materials and Methods. In vitro antioxidant activities of the plant extract were determined by DPPH and NO scavenging method. Superoxide ani...

The mother tinctures of desert were screened for antibacterial activity against bacterial strains of Gram-positive and Gram-negative bacteria. Mother tinctures were prepared by maceration process and antibacterial activity of different plants was evaluated and compared by measuring their zones of inhibition. The results indicated that Boerrhavia diffusa mother tincture had excellent activity on...

A taxonomic revision of the genus Tamarix for Iberian Peninsula and Balearic Islands is provided, updating Flora iberica account published in 1993. new dichotomous key species also included. The presence certain number previously cited study area (T. arborea, T. canariensis, dalmatica, mannifera, mascatensis, meyeri, octandra, rosea, tetragyna) discarded or considered doubtful. Seven are accept...

The larva of Aphylla protracta is described and figured. It is characterized by 3rd antennomere subcylindrical, flattened on ventral surface, 4.2 times longer than its widest part. Abdomen with dorsal protuberances well developed on S2-4, reduced on S5, vestigial or absent on S6-9; lateral spines lacking entirely, tergites 5-8 with minute reddish setae, tergite 9 with abundant, small, reddish s...

Three new species of Dactuliothrips Moulton are described, two from Mendoza, Argentina and one from Southern California, USA: D. prosopis sp.n. from Prosopis alpataco (Fabaceae), D. monttea sp.n. from Monttea aphylla (Scrophulariaceae), and D. ephedra sp.n. from Ephedra sp. (Ephedraceae). A revised diagnosis and an illustrated identification key to the nine recognized species of Dactuliothrips ...

stemflow is a part of precipitation which enters in to the soil through stem and branches. in this paper, we studied the stem flow features of anabasis aphylla as a bush and pteropyrum aucheri as a shrub in northwest of isfahan. stemflow production mechanism as well as the effects of canopy cover on this system was investigated during precipitation seasons in 2013 and 2014. a rain simulator was...
