IN THIS STUDY, WE HAVE EXAMINED THE ANTIOXIDANT ACTIVITY AND TOTAL PHENOLIC CONTENT OF DIFFERENT EXTRACTS (INCLUDING WATER, METHANOL, WATER : methanol and acetone) of Nerium oleander L. grown in the north of Iran by employing various in-vitro assay, i.e. DPPH free radical scavenging, reducing power and total antioxidant capacity through the Mo (VI) reduction. The extracts showed different level...

Oleander poisoning, though widely seen in the Mediterranean region, is rarely Nepal. The poisonous effect of fodder due to accidental ingestion different parts ‘oleandrin’ which contains cardiac glycosides called cardenolides causing mortality animals. In our study, 8 lactating cows were affected after oleander leaves accidentally mixed and chopped with Napier. After fodder, out cows, 5 died in...

symptoms of the leaf scorch disease on the leaves of oleander infected by xylella fastidiosa appearing for the first time in lebanon were confirmed by elisa tests and anatomical observations of sections of petioles by a scanning electron microscope. xylella fastidiosa was detected in the xylem forming bacterial aggregates in the lumen of tracheary elements. the bacterium colonizes and invades t...

The importance of genetic variation for sustaining biological diversity and evolutionary processes is widely accepted. The present study aims to investigate the phylogenetic relationships among five selected species of Apocynaceae collected from various regions of Pakistan using chloroplast gene (rps11) which encode ribosomal protein of smaller subunit11. For this purpose rps11 gene was amplifi...

This study screened the antidiarrhoeal, antimicrobial and cytotoxic effects of ethanol-extracted leaves of yellow oleander (Thevetia peruviana). The extract was tested against castor oil-induced diarrhoea in a model of albino rats and showed significant antidiarrhoeal activity (P<0.01). Disc diffusion technique was used to test the in vitro antibacterial activities of the extract and exhibited ...

We compared the capacity to accumulate airborne heavy metals of two lichens (Flavoparmelia caperata and Parmotrema chinense) and one higher plant (Nerium oleander) at a very densely populated urban site near Naples. After 15, 45, 75, and 120 days of exposure at four sites with different levels of air pollution, equal portions of thalli and 20 leaves were collected, and four environmentally sign...

Nerium oleander var. ‘Villa Romaine’, commonly called oleander, is an ornamental shrub that exists in Tunisia the wild and cultivated form. This plant frequently propagated produced nurseries used urban plantings on roadsides. The effects of nature plants (spontaneous or cultivated), climatic conditions (localities), altitude (from 6 to 447 m) seed shape, size, germination Tunisian populations,...

In this project, studies were conducted to 1) develop a method to detect and differentiate multiple strains of Xylella fastidiosa in individual glassy-winged sharpshooters (GWSS,) and 2) determine the relative ability of an individual GWSS to simultaneously retain or transmit two strains of X. fastidiosa. Strain-specific primers were developed that can detect and differentiate the Pierce’s dise...
