Characterization Of Bioactive Phytochemicals From The Stem Bark Of African Mahogany Khaya Senegalensis (Meliaceae), Huaping Zhang
Characterization Of Bioactive Phytochemicals From The Stem Bark Of African Mahogany Khaya Senegalensis (Meliaceae), Huaping Zhang
All Dissertations
ABSTRACT
African mahogany Khaya senegalensis (Desr.) A. Juss (Meliaceae) is a large tree growing mainly in the sub-Saharan savannah forests from Senegal to Uganda. This plant is one of the most popular medicinal meliaceous plants in traditional African remedies, used as a bitter tonic, folk and popular medicine against malaria, fever, mucous diarrhea, and venereal diseases as well as an anthelmintic and a taeniacide remedy. Its extracts and chemical constituents have been the subject of extensive phytochemical and pharmacological investigations since 1960s. Anti-inflammatory, anti-bacterial, anthelmintic, and antiplasmodial activities of plant extracts have been reported. Limonoids with anti-feeding, feeding deterrent and …
Optimization Of Biodiesel Production From Crude Cottonseed Oil And Waste Vegetable Oil:Conventional And Ultrasonic Irradiation Methods, Xiaohu Fan
All Dissertations
Biodiesel, derived from the transesterification of vegetable oils or animal fats with simple alcohols, has attracted more and more attention recently. As a cleaner burning diesel alternative, biodiesel has many attractive features including: biodegradability, nontoxicity, renewability and low emission profiles.
Although cottonseed oil was the first commercial cooking oil in the U.S, it has progressively lost its market share to some vegetable oils that have larger production and less cost. However, regarding the active researches on biodiesel production from vegetable oils, there is a promising prospective for the cottonseed oil as a feedstock for biodiesel production, which may enhance the …
Assessment Of A Pilot Nutrition Education Program For Hispanic Youth And Their Parents, Maria Rossi
Assessment Of A Pilot Nutrition Education Program For Hispanic Youth And Their Parents, Maria Rossi
All Theses
Obesity and overweight are increasing at epidemic proportions in South Carolina for both adults and children, particularly affecting minority groups. Hispanic populations residing in South Carolina are not the exception. It is important to provide nutrition education, exercise, and behavior interventions as they are the foundations to treat parents and children who are overweight, obese, or are at risk for overweight and obesity. This study used quantitative and qualitative methods to examine the effectiveness of a nutrition and physical activity program, 'Jump into Food and Fitness' with the Hispanic population and to determine the effectiveness of the program on knowledge, …
Secondary Metabolism Inducing Treatments During In Vitro Development Of Turmeric (Curcuma Longa L.) Rhizomes, Matthew M. Cousins, Jeffrey W. Adelberg, Feng Chen, James Rieck
Secondary Metabolism Inducing Treatments During In Vitro Development Of Turmeric (Curcuma Longa L.) Rhizomes, Matthew M. Cousins, Jeffrey W. Adelberg, Feng Chen, James Rieck

Turmeric (Curcuma longa L.) plants that were grown in vitro for 17 or 22 weeks as a fed-batch culture in 2.5 L vessels yielded 39 to 43 g and 62 to 70 g of fresh rhizomes per vessel, respectively (95 % confidence interval). The MS liquid medium was maintained at 6 % sucrose through media addition twice during the experiment. Various methods were employed in attempts to increase secondary metabolism. Antioxidant and total phenolics assays were employed to characterize phytochemical activity. A first experiment exposed four clones to phenylalanine and/or methyl jasmonate (MeJa) from week 12 to 17 in …

Two cottonseed oil biodiesel samples (cottonseed oil methyl esters, COME) produced in Clemson lab, together with other two commercial cottonseed oil biodiesels were evaluated on their engine performance with the No. 2 diesel fuel as a reference. The results revealed that emission of CO, CO2 and NOx from cottonseed oil biodiesels was lower than that of the No. 2 diesel fuel. CO decreased by 13.8%, CO2 by 11.1% and NOx by 10%, though there was no significantly statistical difference at p<0.05. The engine test also showed a slightly higher amount of consumption and less tendency of coke formation from COME than the No. 2 diesel fuel. The oxidative stability study showed COME with acceptable stability. COME exhibited friendly environmental benefits and acceptable stability, demonstrating its feasibility as an alternative fuel.
