Eleven Tunisian natural populations of Lavandula multifida L., from different geographic regions and bioclimates, were assessed for their variability using six polymorphic loci and 35 terpenoids. Isozymes were revealed by 13% gel electrophoresis. Volatiles were analysed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). A high genetic diversity within populations and w...

Wounds are structural and functional disruptions of the skin that occur as a result an injury. Wound healing is complex tissue repair or remodelling process in response to The most common factor causes wounds not properly heal infection. An infection develops when microorganisms enter body, multiply, trigger immune reaction body. This study aims determine activity Jatropha multifida L., Stachyt...

The isolation of intact, high-molecular mass genomic DNA is essential for many molecular biology applications including PCR, endonuclease digestion, southern blot analysis, and genomic library construction. Many protocols are available for the extraction of genomic DNA from plant tissue, and all the protocols have used expensive and hazardous chemical-liquid nitrogen for grinding plant material...

Population differentiation can be driven in large part by natural selection, but selectively neutral evolution can play a prominent role in shaping patters of population divergence. The decomposition of the evolutionary history of populations into the relative effects of natural selection and selectively neutral evolution enables an understanding of the causes of population divergence and adapt...

Antioxidants are vital substances which possess the ability to protect the body from damage caused by free radical induced oxidative stress. A variety of free radical scavenging antioxidants exist within the body which many of them are derived from dietary sources like fruits, vegetables and teas. In this study the antioxidant activity and radical scavenging activity of methanolic extracts of s...
