Yield, Quality and Composition of Cumin Essential Oil as Affected by Storage Period

International Journal of Analytical Mass Spectrometry and Chromatography 2019年第1期7卷 9-17页

作者： Abdlazim Mohamed ali hana jumma ali jumma Faculty of Agriculture Nile Valley University Atbara Sudan

Essential oils from newly produced (2017) and previous season crop (2016) of cumin (Cuminum cyminum L.) seeds collected from local farmers in Dongla area, north Sudan were extracted and analyzed to determine the effect of storage period on volatile oil yield and quality. The essential oil was extracted using hydro distillation method. Identification of the volatile compounds was performed using gas chromatography-mass spectrometry (GC/MS). Results revealed that oil obtained from cumin (Cuminum cyminum L.) was pale yellow. With respect to oil characteristics, the specific gravity, refractive index, acid value, ester value and other quality characters were not significantly different between the stored and newly harvested seeds. Thirty-eight compounds were separated and identified in cumin seeds essential oil in both seasons with some minor differences in some components between 2016 and 2017 samples. Major effective components of cumin seeds volatile oil were cumin alcohol (4-isopropylbenzyl alcohol), cumin aldehydes as 4-Isopropylbenzaldehyd and 7,7-dimethylbicyclo (4.1.0) hept-3-ene-4-carbaldehyde known as carenal, terpinenes as γ-terpinene and α-terpinene (1,4-Cyclohexadiene, 1-methyl-4-(1-methylethyl) and 1,3-cyclohexadine-1-methanol, 4(1-methethyle)-), β-pinene, o-cymene and p-menthadienol in both stored and newly harvested samples. Differences between the samples season wise were very minor with respect to type of volatile components but percentage oil yield was largely decreased by storage period.

Dental practitioners must be well informed about the pathology, complications and treatment options associated with bleeding disorders patients. Prolongation of bleeding time can seriously complicate the patient’s condition during and after surgery, especially if there is iron deficiency anemia or any other condition accompanied by a decrease in hematopoiesis. For this reason, the dentist surgeon must be aware about the presence of such diseases in advance, in order to prevent the development of bleeding and its undesirable consequences promptly. Blood loss becomes apparent when blood exits through a natural opening in the body, for instance the nose & mouth. In this article, common medical bleeding situations with the potential to compromise the successful outcome of dental surgical procedures have been presented. Bleeding disorders is a disease group, which can be classified as deficiencies of coagulation factors, platelet disorders, vascular disorders, fibrinolytic defects and so on. Fragile blood vessels can cause bleeding, petechiae, bruising, etc. In most cases, vascular disease does not cause serious blood loss, with the exception of hereditary hemorrhagic telangiectasia. In this paper, we discuss the most common hereditary diseases associated with a deficiency of plasma coagulation factors VIII and IX, the disease of platelet deficiency (Glansman disease), the prophylaxis of bleeding in this kind of patients, and the effect of drugs on coagulation processes as well.
