Background and Aims: Sideritis species (Lamiaceae) which are quite widespread in the Mediterranean region represented by 46 53 taxa Turkey, often used as a antirheumatic, anti-inflammatory, antimicrobial diuretic remedies. Methods: In this study, infusion (INF), essential oil (EO) methanolic extract (ME) of chemical compounds prepared from aerial parts albiflora Hub.-Mor. (endemic) were investi...

Previous studies suggested the existence of a correlation between 26 Al relative crystallisation ages and mineralogical and bulk chemical compositions of ferromagnesian chondrules from the Bishunpur and Semarkona unequilibrated ordinary (Mostefaoui et al., 2002; Tachibana et al., 2003). However, because the precision in 26 Al ages was moderate, these correlations are questionable. Here, we repo...

pomegranate juice (pj) and its products are directly used in foods due to their pleasant taste and palatability as well as preservative effects. in spite of useful effects of essential oils such as zataria multiflora boiss essential oil (zeo) on prolonging shelf-life of foods, their application is restricted due to their vigorous taste and aroma. in the present study, physicochemical characteri...

A method of clay mineral sample preparation for electron microprobe analysis has been developed in which a film of clay plus 10-12 wt. % colloidal graphite is deposited on a porous ceramic disc using a specially designed suction device. Correction procedures are used to obtain quantitative elemental analyses representing the average chemical composition of the prepared sample. A statistical tec...
