Objective: To evaluate chemical compositions, antioxidant and wound healing properties of Algerian Artemisia absinthium essential ***: The chemical composition of the essential oil from Artemisia absinthium was analyzed by a combination of GC-FID and GC/MS. The antioxidant capacities including the total antioxidant capacity, DPPH· and ABTS+· scavenging capacities were measured. The wound healing potential was assessed by the excision wound model of rats. The wounds were treated daily with an ointment prepared with two concentrations(5% and 10%) of Artemisia absinthium essential oil. The percentage of wound contraction was determined and wound healing was also evaluated by histological examination of the healed skin. Results: The main component of Artemisia absinthium essential oil was camphor(48%) followed by chamazulene(10%) that was responsible for the dark blue color of the oil. Artemisia absinthium essential oil exhibited moderate antioxidant activity compared with BHT and Trolox. All preparations showed significant effects on wound contraction and the ointment prepared with 10% of essential oil was effective as the reference drug ***: The essential oil of Artemisia absinthium shows moderate antioxidant activity. The 10% ointment enhances skin wound re-epithelialization and speeds up the healing process. The essential oil of Artemisia absinthium may be used as an alternative drug for wound healing.

Objective: To investigate the in vitro antiproliferative action of essential oil from Salvia officinalis L.(S. officinalis) grown in Sicily(Italy), and its main components on hormone-dependent cancer cell lines. Methods: S. officinalis essential oil was prepared by hydrodistillation. The actions of the S. officinalis essential oil and its three principal components(毩-thujone, 1,8-cineole and camphor) were evaluated in LNCaP cells(prostate carcinoma), MCF7 cells(breast carcinoma) and He La cells(cervical carcinoma) at various dosages and diverse time points. Cell viability and proliferation were estimated using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Results: S. officinalis essential oil at doses of 100 μg/m L and 200 μg/m L induced a significant reduction of cell viability in MCF7, LNCa P and He La cell lines after a 48-hour incubation. The same cell lines also showed decreased cell viability when they were treated with a mixture of three major components of the essential oil, at doses of 100 μg/mL and 200 μg/mL, after a 48-hour incubation. Conclusions: These preliminary results could shed light on the formulation of new therapeutic agents with antiproliferative activity. Thus supplementary investigations are fundamental to examine the molecular mechanisms of the anticancer effects of this species of Salvia in cancer cells and to achieve confirmation of its in vivo anticancer activity.

A probabilistic analysis was performed on soil arsenic concentration data from 4 brownfield sites at Beijing （Chaoyang and Haidian Districts）, involved in environmental assessment studies. The available data sets were processed to provide a statistical characterization of the background populations and differentiate ＂anomalous data＂ from the natural range of variation of arsenic concentrations in soil. The site-specific background distributions and the existing wide-scale background values defined for the Beijing area were compared, discussing related implications for the definition of metal contamination soil screening levels （SSLs） in site assess- ment studies. The statistical analysis of As data sets discriminated site-specific background populations, encompassing 88% to 94% of the sample data, from oufliers values, associated with either subsoil natural enrichments or possible anthropogenic releases. Upper Baseline Concentration （UBC） limits （＋ 2σ level）, including most of the site-specific metal background variability, were derived based on the statistical characterization of the background populations. Sites in the Chaoyang South District area had UBC values in the range 10.4-12.6mg·kg^-1. These ranges provide meaningful SSL values to be adopted for As in local site assessment studies. Using the wide-scale background value for the Beijing area would have erroneously classified most of the areas in the subject sites as potentially contaminated.
