Abstract:

Chironji oil extraction from the Buchanania lanzan seeds using Soxhlet extraction and cold pressing method has been reported. Soxhlet extraction of Chironji oil was carried out using polar solvents such as methanol (M), ethanol (E), dichloromethane (DCM), and ethyl acetate (EA), nonpolar solvents like petroleum ether (PE) and hexane (H), and a combination of polar and nonpolar solvents in various ratios such as PE: M (1:1), DCM:M (1:1, 2:1) and DCM:E (1:1). The Soxhlet extraction using petroleum ether provided the higher oil extraction yield (50.16%) than cold press method (21.57%), but the cold-pressed oil was superior in quality (e.g., no loss of aroma). Chironji oils extracted by the solvent extraction method and cold-pressed method have been analyzed using gas chromatography and mass spectroscopy to get the composition of fatty acids which have nutritional and medicinal significance. Also, the existence of various functional groups such as alkanes, ester, and alkene in the Chironji oil were confirmed by Fourier Transform Infrared Spectroscopy of the extracted oil. Analysis of oil by phytochemical tests and physicochemical properties was carried out, and the presence of tannins, flavonoids, saponins, steroids, and terpenoids was confirmed.
