The present study is a contribution to the enhancement of Ivorian traditional medicine, by carrying out bio-tolerance tests an aqueous extract aerial parts Crotalaria retusa (EACr) in mice and rats according guidelines Organization for Economic Co-operation Development (OECD) 423 407, respectively. doses 2000 5000 mg/kg body weight (BW) were used acute toxicity. For subacute toxicity which last...

This study addresses the adaptation of Nitraria sphaerocarpa to blown sand at the edge of a desert oasis with regard to the aspects of soil seed banks, seedlings, and population. Horizontally, the total number of seeds per unit area decreased from the shrub canopy center to intershrub areas, and most seeds were found under shrub canopies. Vertically, the highest proportion of seeds was found at...

Vegetation root water uptake is one of the most central transport processes along soil-vegetation-atmosphere interface particularly in (semi-)arid ecosystems. The identification and quantification activities patterns arid vegetation remain challenging. This paper aims at quantitative examination behaviors Nitraria, a prevalent desert species environments, during growth phase via multivariate li...

A new species of Hoya R.Br. from Sulawesi (Indonesia), Hoya isabelchanae Rodda & Simonsson, is described and illustrated. It is one of the largest flowered species in Hoya section Acanthostemma (Blume) Kloppenb. Its flowers are of comparable size to those of Hoya benchaii Gavrus et al., Hoya kloppenburgii T.Green, Hoya rundumensis (T.Green) Rodda & Simonsson and Hoya sigillatis T.Green ssp. sig...

arid and semi-arid lands cover around one-third of the world's terrestrial expanse and their widespread plantdistributions provide these areas with a high potential for sequestering carbon. vegetation management for developingshrub or tree species in arid and semi-arid regions is one inexpensive and multi-purpose approach for decreasing co2.this study assessed the potential of carbon sequestrat...

In the present study, the anti-diabetic effect of aqueous extract of Sida rhombifolia ssp. retusa (Malvaceae) leaves was studied in normal and streptozotocin (STZ)-induced (60 mg/kg, single intraperitoneal injection) diabetic rats. Hypoglycemic activity in normal rats was tested after administration of 200 mg/kg of extract. Aqueous extract showed a 15% reduction in plasma glucose level after 1....
