The use of plants is as old as the mankind. Natural products are cheap and claimed to be safe. They are also suitable raw material for production of new synthetic agents. Rosemary (Rosmarinus officinalis Linn.) is a common household plant grown in many parts of the world. It is used for flavouring food, a beverage drink, as well as in cosmetics; in folk.medicine it is used as an antispasmodic i...

The effects of rosemary extract, chitosan and carnosine, added individually or in combination, on colour, lipid stability and sensory attributes of beef patties were investigated. All samples were stored for up to 15 days at 4 ± 1 oC. Surface colour (Hunter L*, a* and b* values), and lipid oxidation (2-thiobarbituric acid reactive substances) were measured on days 0, 1, 3, 6, 9, 12 and 15 of st...

Supercritical fluid extraction (SFE) is an innovative, clean and environmental friendly technology with particular interest for the extraction of essential oil from plants and herbs. Supercritical CO(2) is selective, there is no associated waste treatment of a toxic solvent, and extraction times are moderate. Further, supercritical extracts were often recognized of superior quality when compare...

the antifungal potential of essential oils of thyme (thymus vulgaris l.), rosemary (rosmarinus officinalis l.), and laurel (laurus nobilis l.) was determined. to establish this antifungal potential, two molds related to feed spoilage, namely, aspergillus flavus and aspergillus parasiticus, were selected. the agar dilution method was employed for the determination of antifungal activities. the i...

A total of 220 broiler chicks in five groups were used to reveal the effects of different levels of 0.0, 1.5, 3.0 and 6.0 mL/L rosemary extract along with sodium nitrate (27.4 mg/L) in drinking water as compared to the control (without any supplement in water) on performance and antioxidant potential of treated broiler chickens. Body weight gain and feed conversion ratio were negatively affecte...

Although rosemary essential oil (EO) shows many biological activities, its topical benefits have not been clearly demonstrated. In this work, we assessed the effects on skin hydration and elasticity of rosemary EO after topical application via gel vehicles in human volunteers. To improve its topical efficacy, rosemary EO was loaded into lipid nanoparticles (NLCs) consisting of cetyl palmitate a...

The use of herbs in the food industry has recently increased significantly because of their antioxidant action on lipid degradation, besides their traditional role in food aroma. In particular, rosemary (Rosmarinus officinalis L.) extracts have proved to possess such useful antioxidant properties. The present research that reports on a study on the morphological and chemical characteristics, co...

Background: A sequence of time-dependent changes can affect the brainchr('39')s functional capacity. Aims: This study aimed at investigating the effects of forced aerobic exercise (FAE) versus the rosemary extract (RE) on the learning abilities and oxidative stress modulation in rats. Methods: Young and old rats received daily FAE and RE for 3 months. Using the passive avoidance (PA) test, we...
