Interest in alternative medicine and plant-derived medications that affect the "mind" is growing rapidly since last two decades. The aim of the present study was to investigate the effects of ethanolic extract of flower of Plumeria rubra (PR) along with its fractions in the elevated plus-maze (EPM) model of anxiety. The P. rubra extract or its fractions was(More)
The aim of the present study was to evaluate the antidyslipidemic effect of ethanolic extract of Rheum emodi rhizomes and its constituents in Triton-WR-1339 and high-fat diet (HFD)-induced dyslipidemic rats. In preliminary screening, the ethanolic extract showed significant activity in Triton-treated rats. Bioassay-guided fractionation of the ethanolic(More)
Whitebacked planthopper (WBPH) along with brown planthopper (BPH) has emerged as a major pest of rice in several Asian countries. Development and cultivation of varieties resistant to both planthoppers is an ecologically acceptable strategy to manage these pests. Sinna Sivappu, a Sri Lankan landrace, was reported to be resistant to both planthoppers. While(More)
A series of Lupeol-based chalcones have been synthesized aiming to enhance the therapeutic efficacy of parent compound, the novel compounds were evaluated for their antidyslipidemic activity in triton-WR 1339 induced hyperlipidemic rats. Among the ten synthesized chalcones, the most active K4, K8, and K9 reversed the plasma levels of TC by (24, 25, 27 %),(More)
The field of cancer research and treatment has made significant progress, yet we are far from having completely safe, efficient and specific therapies that target cancer cells and spare the healthy tissues. Natural compounds may reduce the problems related to cancer treatment. Currently, many plant products are being used to treat cancer. In this study,(More)
The present study was designed to evaluate the anti-ulcerogenic properties of an alkaloid chromane, rohitukine from Dysoxylum binectariferum. Anti-ulcer potential of rohitukine was assessed in cold restrained, pyloric ligated and ethanol induced ulcers in rats. In addition, rohitukine was tested in vitro for H+ K+-ATPase inhibitory activity in gastric(More)
A number of pathogenic fungi like Candida, cannot survive upon damage to mitochondrial DNA (mtDNA) while the budding yeast can tolerate the damage therefore we chose Saccharomyces cerevisiae as a model system for this study. Since a number of potent antifungals have originated from various natural sources, we decided to use a triterpenoid and tetraterpenoid(More)
Gastric ulcer is a very common gastrointestinal disorder affecting a large number of people worldwide. It arises due to an imbalance between aggressive (acid, pepsin and Helicobacter pylori infection) and protective (mucin secretion, prostaglandin, epidermal growth factors and bicarbonate) factors in the stomach. In this study, the gastroprotective activity(More)
