Argyreia nervosa has been used as an antiulcer in ethano medicine. So the aim of the present study was to evaluate the leaves of the plant for its antiulcer potential and to isolate the bioactive compounds. On the basis of the result of the preliminary screening for antiulcer potential of different fractions of methanolic extract of Argyreia nervosa leaves; n-butanol fraction was charged into s...

Cross incompatibility of wild Manihot species with cassava (M. esculenta) can impede their utilization for improving this cultigen. We tested whether compatibility could be determined based on electrophoresis results. Manihot pilosa, M. glaziovii, M. reptans, and M. cearulescens were tested. These species were allowed to hybridize with cassava to determine whether hybridization coincides with t...

Abstract Compositae family comprises the largest number of species invasive alien plants (IAPs) in China. Two IAPs can co-invade same habitat. Drought alter litter decomposition and soil enzyme activities. This study aims to estimate independent combined effects two composite (Bidens pilosa Solidago canadensis) on activities under drought. A polyethylene litterbags experiment (5 g litters B. pi...

A significant part of drug discovery in the last forty years has been focussed on agents to prevent or treat cancer. This is not surprising because, in most developed countries and, to an increasing extent, in developing countries, cancer is amongst the three most common causes of death and morbidity.

The application of tissue culture techniques, particularly in the area of embryo rescue, has had a major impact on the maintenance and development of hybrid embryo from wide crosses. Embryo rescue techniques are directed towards obtaining more efficient survival of embryos in situations where very immature embryos are to be cultured. An in vitro embryo rescue culture technique has been develope...
