Introduction: Turmeric as the scientific name of Curcuma longa L. belongs to Zingiberaceae family. Extraction method is effective on the percentage and type of chemical compounds present in the extract. The aim of this study was phytochemical surveying of turmeric soxhelt extract by using instrumental analysis and determination of flavonoids and flavenols contents in different extraction methods.
Materials & Methods: Phytochemical tests were done on ethanolic soxhelt extract to determine secondary metabolites and different instrumental analysis methods in order to verify the existence of curcuminoids on it extract took place. The content of flavonoids and flavonol extracts were measured by different extraction methods (maceration, ultrasonic and soxhlet) using quercetin as a standard.
Findings: The results of phytochemical studies have confirmed the presence of alkaloid, flavonoids and glycosides compounds and the absence of tannins and saponins in the ethanolic soxhelt extract. The results of IR, UV, GC and GC / Mass indicate the presence of curcuminoids in turmeric extract by soxhelt extraction. The results of statistical tests indicated that the highest content of flavonoids and flavenols belongs to the extraction with hexane and ethanol.
Discussion & Conclusion: In soxhelt method despite requiring high temperature and using of hot solvent, the curcuminoids structure was retained and this extraction method may be a suitable method for curcumin extraction from turmeric plant. Also suitable method for extracting flavonoids and flavonoid compounds is extraction with two solvent “ethanol and hexane“. |
