All Rights Reserved. Chemical composition of Egyptian and UAE propolis. Said, Sobhi A.; Khan, Saeed A.; Ahmad, Iqbal; Ali, Hayam S. (Dubai Pharmacy College, Dubai, United Arab Emirates). Pakistan Journal of Pharmaceutical Sciences, 19(1), 58-61 (English) 2006 University of Karachi, Faculty of Pharmacy. CODEN: PJPSEN. ISSN: 1011-601X. DOCUMENT TYPE: Journal CA Section: 63 (Pharmaceuticals) The chem. compn. of propolis samples obtained from Behera, Egypt and Dubai, UAE, have been investigated by GC-MS and thirty four compds. have been tentatively identified. Some of these compds.Some commonly used reagents like 1592-38-7 and 1929-29-9 are used in this experiment. have not been reported previously in Egyptian propolis from different regions. The Egyptian sample contains a high amt. of aliph. (13.7%) and arom. (14.4%) acids. The alcs., phenols and esters account for about 17.0% of the total content analyzed. Some anthraquinone and flavone derivs. have also been detected (10%). The UAE sample is characterized by the presence of a high content of aliph. acids (15.2%) and a low content of arom. acids (4.3%). The aldehydes, alcs., phenols and esters amt. to about 9%. In addn. to these some other compds. (high mol. wt. alkanes, sugar derivs., anthraquinone derivs. and flavone derivs.) are also present to the extent of about 33%. .
