Essential oils and various extracts of Heracleum persicum, Nigella arvensis, Cinnamomum zeylanicum and Zingiber officinale were assessed by two methods of disk and solution of BSL. Data were processed in probit-analysis program to estimate LC 50 values. All of the tested fractions have exhibited more cytotoxicity in the solution method. Essential oils of H. persicum and C. zeylanicum have shown the most cytotoxicity with LC 50 values 0.007 and 0.03 µg/ml respectively. None of aqueous extracts showed significant cytotoxicity. The analysis of the essential oil of H. persicum showed the hexyl butyrate and octyl acetate as the main compounds. These results suggest some limitation for using of these spices in diet. Furthermore, these plants could be considered as a source of cytotoxic compounds which might be studied in more details.

Consumers' perception is widely varied in accordance with the Communication quality, call service, facilities, price, customer care and service provider's attributes. A structured questionnaire was developed to collect the required primary data from the consumers. Collected data were analysed, reliability and factor analysis were carried out. The outcome of this research shows a comprehensively integrated framework to understand the relationships among several dimensions. The study shows communication and price were most influential and most preferential factors in selecting telecommunication service provider. However, product quality and availability has a significant impact on consumer perception choice in selecting cellular mobile service provider.
