Determination of the free radical scavenging activity of Lycium extracts
(Consultants Bureau, 2003)Lycium species growing in Turkey have not so far been studied sufficiently. For this reason, non-polar and polar extracts obtained from the fruits of Lycium barbarum L. and L. ruthenicum Murray (Solanaceae) were assessed ... -
Fatty acid composition of pistachio nuts in Turkey
(Consultants Bureau, 2003)In this study oil yields and fatty acid compositions in the kernels of two varieties (Uzun and Siirt) of pistachio grown in different region of Turkey were investigated. Kernel oils were obtained by Soxhlet extraction using ... -

The glycosidically bound volatile compounds of Taxus baccata
(Consultants Bureau, 2003)The steam volatiles obtained from the fresh and dried needles of Taxus baccata (Taxaceae), collected from Turkey after enzymatic hydrolysis, were analyzed by GC/MS. Sixty-three compounds representing 88.6% of the oil ... -
An improved on-line HPLC-DPPH* method for the screening of free radical scavenging compounds in water extracts of Lamiaceae plants
(Consultants Bureau, 2003)An on-line HPLC-1,1-diphenyl-2-picrylhydrazyl (DPPH*) method has been improved for the detection of polar and nonpolar radical scavenging compounds from complex plant extracts. Eight water extracts were prepared from ... -
Isolation of some soluble and dispersed materials of Oregano Water
(Consultants Bureau, 2003)Recent results obtained on determining the extraction efficiency and composition of organic volatiles in Oregano Water obtained from Origanum onites L are described. Oregano Water was subjected to liquid-liquid extraction ... -
Seed oils of fifteen Ebenus taxa growing in Turkey
(Consultants Bureau, 2001)Oil yields and compositions from seeds of 15 Ebenus taxa growing in Turkey were investigated. The yields were found between 4.0% and 13.0%. The seeds of E. barbigera showed the highest while E. plumosa var. plumosa showed ... -
Studies on Turkish rose concrete, absolute, and hydrosol
(Consultants Bureau, 2003)The production of rose absolute from fresh flowers of the cultivated Rosa damascena Miller was realized using traditional and modem techniques, such as molecular distillation, extraction with liquified gases, etc. Headspace ...
