alcoholic extract of rosemary on oral bacteria, compared to a commercially available herbal dentifrice. Standard strains of Streptococcus mutans (ATCC 25175), Streptococcus oralis (ATCC 9811) and Lactobacillus rhamnosus (ATCC 7469) were used, as well as different toothpastes based on rosemary (TR), on propolis (TH), triclosan (positive control) (TPC) and non-fluoridated dentifrice (negative con...

Medicinal plants represent a significant reservoir of unexplored substances for early-stage drug discovery. Of interest, two flowering Mediterranean plants have been used for thousands of years for their beneficial effects on nervous disorders, including anxiety and mood. However, the therapeutic potential of these plants regarding their ability to target ion channels and neuronal excitability ...

BACKGROUND Phenolic compounds act as food antioxidants. One of the postulated mechanisms of action is chelation of prooxidant metals, such as iron. Although the antioxidative effect is desirable, this mechanism may impair the utilization of dietary iron. OBJECTIVE We sought to determine the effect of phenolic-rich extracts obtained from green tea or rosemary on nonheme-iron absorption. DESI...

In the present work, four green processes have been compared to evaluate their potential to obtain rosemary extracts with in vitro anti-proliferative activity against two colon cancer cell lines (HT-29 and HCT116). The processes, carried out under optimal conditions, were: (1) pressurized liquid extraction (PLE, using an hydroalcoholic mixture as solvent) at lab-scale; (2) Single-step supercrit...

The essential oil of Rosmarinus officinalis L. (rosemary) was obtained by hydro-distillation and analysed by gas chromatography-mass spectrometry. Sixty-two constituents were identified, representing 98.06% of the total oil content. Oxygenated monoterpenes were the predominant components. The rosemary oil was characterized as having prominent (> 5%) contents of camphor (18.9%), verbenone (11.3%...

Rohlík B-A., Pipek P., Pánek J. (2013): The effect of natural antioxidants on the colour and lipid stability of paprika salami. Czech J. Food Sci., 31: 307–312. The typical red colour of paprika salamis is a very important quality attribute but it is also very susceptible to oxidation. Rosemary extracts and lycopene appear to be efficient antioxidants for dry fermented sausages. The complicated...

Background The aim of present study was to evaluate antileishmanial effects of Lavandula angustifolia (L. angustifolia) and Rosmarinus officinalis (R. officinalis) medicinal plants essential oils and nano-emulsions on Leishmania major (L. major). Methods The present study was performed in Leishmaniasis Reference Lab at Mazandaran University of Medical Sciences, Iran during 2016-2017. The IC50...

Oral candidiasis causes pain in oral cavity or tongue. Antifungal drugs are commonly used for the treatment of candidiasis, however, there could be several problems such as side effects, drug resistance, or contraindication to concomitant use with drugs already taken. The development of substituting antimicrobial agents, which could be used internally or as gargling agents, is expected. Some es...

The effect of feed supplementation with natural α-tocopherol, rosemary, green tea, grape seed and tomato extracts on the oxidative stability of broiler meat was investigated by measuring lipid oxidation, protein oxidation and α-tocopherol content of breast muscle. Supplementation with α-tocopheryl acetate at a dietary concentration of 200 ppm was used as a control. The broilers were fed a diet ...
