Natural matrices are important sources of new antitumor and antimicrobial compounds. Species such as Laurus nobilis L. (laurel) might be used for this purpose, considering its medicinal properties. Herein, in vitro activity against human tumor cell lines, bacteria, and fungi was evaluated in enriched phenolic extracts. Specifically, methanol and aqueous extracts of wild and cultivated samples o...

Bay laurel (Laurus nobilis) is an agriculturally and economically important dioecious tree in the basal dicot family Lauraceae used in food and drugs and in the cosmetics industry. Bay leaves, with their abundant monoterpenes and sesquiterpenes, are used to impart flavor and aroma to food, and have also drawn attention in recent years because of their potential pharmaceutical applications. To i...

In this study efficacy of essential and fixed oil Laurus nobilis L., on controlling Aphis fabae Scopoli that grows Vicia faba L. (Fabaceae) has been studied by experiments set up in the laboratories Çukurova University Biology Plant Protection Departments 2016-2017. Fixed oils had previously found to be effective aphids according death rate Abbott test values, but they also phytotoxic effects p...

laurus nobilis l. (sweet laurel) is one of the volatile oil bearing plants of lauraceae family. it is cultivated in different parts of iran and its leaves and fruits have been used in food, cosmetics and pharmaceutical industries. there are a few reports about the effects of some environmental conditions on the quality and quantity of laurel volatiles. the goal of our work was to search the sea...

infection with helicobacter pyloriis the most common cause of stomach and duodenal ulcers. about more than 80 % of people are infected with h. pylori in developing countries. h. pyloriuses urease enzyme product “ammonia” in order to neutralize and protect itself from the stomach acidic condition and urease enzyme activity has been shown to be essential to the colonization of h. pylori. inhibito...

In Tunisia, more precisely in semi-arid and arid areas, drought accentuated by the superficial evaporation of water leads to a gradual increase salinity, which is limiting factor crop production. these highly salty ecosystems, some plants grow naturally; however, various species show different levels tolerance salinity during their development. The germination seeds most sensitive stage this ab...

In this project, total phenolic and flavonoid contents of the aqueous extract of Laurus nobilis L. leaves were evaluated by colorimetric methods. These natural products which are found in plants extracts, can be considered as reducing and stabilizing agents in the synthesis of metal nanoparticles. Regarding to high amounts of these compounds in the extract, silver nanoparticles were synthesized...
