Abstract
The aforementioned literature survey provoked us to isolate tobacco tar by specific filters to analyse it by LC/MS analysis and to confirm the efficiency of such types of filters. In addition, the study includes the effect of the isolated tar on certain strains of respiratory micro-organisms and the effect on microbial adherence Avocado trees are vulnerable to bacterial, viral, fungal, and nutritional diseases (excesses and deficiencies of key minerals). Disease can affect all parts of the plant, causing spotting, rotting, cankers, pitting, and discoloration The genus Persea is widely distributed all over the world comprising several species. Some of these species have been used medicinally. The reported medicinal and industrial values encouraged investigators to examine the available Persea species with the aim of their evaluation. The following is a literature survey about chemical and biological investigations of genus Persea.
