The leaves of Rosmarinus officinalis harvested from three different locations of Turkey were extracted by both methanolic and supercritical CO(2) extraction. Subsequently, six extracts and the active compounds, carnosic acid, and rosmarinic acid were applied to various human cancer cell lines including NCI-H82 (human, small cell lung, carcinoma), DU-145(More)
Rosmarinus officinalis is widely found in the lands of Aegean and Mediterranean regions of Turkey. Stem explants of very young shoots were cultured in both woody plant medium (WPM) and Murashige and Skoog (MS) media supplemented with 7g/L agar, 30g/L sucrose, and 1 and 3mg/L naphthaleneacetic acid (NAA) for callus initiation. Induced calli were subcultured(More)
The foam collapse and foam formation properties of four different simulated fermentation media were compared in the presence and absence of natural oils. It was found that optimum effective natural oil concentration resulting in optimum foam suppression did not always correspond with the optimum for foam collapse, nor the optimum for maximum foam collapse(More)
Most agroindustrial wastes generally undergo various thermal treatments during processing stages. The aim of this study was to determine the effect of different heat treatment methods on hydrolysis efficiency of such natural substrates. It was found that a wet thermal treatment generally increases the rate and degree of hydrolysis, while a dry one has a(More)
Lactonic sophorolipids were produced by the yeast Candida Bombicola ATTC 22214 (Torulopsis bombicola) in a 3L bioreactor using batch cultivation, with corn oil and glucose as carbon sources. The main compound of the lactonic mixture was separated from the mixture by column chromotography and was identified as 17 hydroxyoctadecanoic-1’,4’’-lactone 6’ 6’’(More)
Bioactive compounds extracted from plants are widely used. The natural habitats for a large number of plants are rapidly destroyed leading to extinction of many valuable and even endemic species. Studies on the production of plant metabolites by callus and cell suspension cultures have been carried out on an increasing scale since the end of the 1950's. The(More)
