Abstract

Introduction: Curcuma longa L. (turmeric) belongs to the Zingiberaceae family. The aim of this study was to evaluate the phytochemicals present in turmeric. The method of Extraction has an effect on the percentage and type of chemical compounds extracted. Instrumental analysis was used to determine the Flavonoid and Flavanol content of turmeric utilizing different Extraction methods. Materials & Methods: Phytochemical tests were performed on an ethanolic Soxhlet extract to determine the secondary metabolites present. Different methods of instrumental analysis were used to verify the presence of Curcuminoids. Flavonoid and Flavanol content was evaluated using different Extraction methods. They included maceration, ultrasonic, and Soxhlet Extraction. Quercetin was utilized as standard. Findings: Phytochemical studies confirmed the presence of alkaloids, Flavonoids, and glycosides in turmeric ethanolic extracts. Tannins and saponins were however absent. IR, UV, GC, and GC/MS indicate the presence of Curcuminoids in turmeric extract prepared by Soxhlet Extraction. Statistical analysis indicated that the highest Flavonoid and Flavanol content was from hexane and ethanolic extracts. Discussion & Conclusions: Despite the requirement of high temperature and the use of a hot solvent in Soxhlet Extraction, the Curcuminoids structure was retained. This method of Extraction may be suitable for Extraction of curcumin from the turmeric plant. Another suitable Extraction method for Flavonoid and Flavanol compounds is the use of both ethanol and hexane as solvents.
