In this study, the minor and major mineral contents of 31 kinds of medicinal and aromatic plant collected from the south region of Turkey in 2004 year were established by inductively coupled plasma atomic emission spectrometry (ICP-AES). The samples were composed of Al, Ca, Fe, K, Mg, Na, P and Zn. The highest mineral concentration were measured between 57.70-2962.74 mg/kg Al, 1160.04-16452.88 mg/kg Ca, 44.83-1799.5 mg/kg Fe, 3570.73-27669.72 mg/kg K, 477.17-4313.59 mg/kg Mg, 1102.62-20912.33 mg/kg Na, 443.60-9367.80 mg/kg P and 7.18-48.36 mg/kg Zn. The highest values of Ca, K and P were established in Foeniculum vulgare (bitter fennel) (16452.88 mg/kg), Ocimum minumum (basil) (27669.72 mg/kg) and F. vulgare (bitter fennel) (9367.80 mg/kg), respectively. The heavy metal contents were determined too low in all samples. Nitrate and nitrite contents of samples were analysed using the phenolicdisulphonic acid method and the diazotisation method of the American Public Health Association, respectively. These nitrate and nitrite values were established to vary widely depending on the different plant species. While nitrate contents were high in most cases and varied from 12.15 mg/kg lime flover (Tilia corata) to 238.85 mg/kg myrtle (Myrtus communis), nitrite contents were established between 3.69 mg/kg sesame (Sesamum indicum) to 52.70 mg/kg basil (Ocimum minumum). Generally, nitrate contents of samples were found very high compared with nitrite values. © 2007 Elsevier Ltd. All rights reserved.

Juniperus drupacea fruit is widely used in traditional and complementary medicine in Turkey for the treatment of different diseases in various forms such as molasses and tar. This study was carried out to evaluate the phenolic compounds, organic acid, sugar, and macro- and micromineral distributions of methanol and water extracts of J. drupace fruit, as well as their antioxidant and antimicrobial potential. For this purpose, total phenolic content by spectrophotometer, phenolics, organic acids, and sugars distributions by HPLC in extracts of J. drupacea fruits, and macro- and micromineral element content by ICP-AES in fruit were determined. 2,2-diphenyl-l-picrylhydrazyl assay (DPPH assay) was used to evaluate in vitro antioxidant activity in extracts. The antimicrobial potential of J. drupacea fruit methanol extract against some gram-positive and gram-negative pathogenic bacteria was evaluated using disk diffusion and minimum inhibitory concentration (MIC) methods. The potassium macroelement and the iron microelement were found at high content in J. drupacea fruit. The total phenolic content in the methanol extracts was higher than the water extracts. Among the individual phenolic compounds, catechin, a flavonoid that was the highest in both extractions, was determined as 300.49 μg/g in methanol extract and 314.88 μg/g in water extract. DPPH scavenging activity was higher in methanol extracts. While the methanol extract of J. drupacea had no-inhibitory effect on the gram-negative bacteria tested, it exhibited a strong inhibition on the gram-positive bacteria Listeria innocua, Listeria monocytogenes, Staphylococcus carnosus, and Enterococcus faecalis.
