Effect of Extraction Solvent on Oil and Bioactives ..., Springer
Commercially available niger (Guizotia abyssinica (L.f.) Cass.) seed was investigated to evaluate the effect of extraction solvent on oil and bioactives composition. For this purpose, niger seeds were subjected to solvent extraction using solvents of different polarity, viz., hexane, petroleum ether, chloroform, acetone, methanol and ethanol. The oil content of niger seeds obtained after
The extraction mixture consisted of approximately 10.0 ± 0.1 g of sunflower collets and 180 mL of ethanol (95%, bp 78 °C), corresponding to a collet-to-solvent ratio of 1:18 (g/mL). The agitation rate was kept constant in all experiments, being sufficient to maintain a well-mixed fluid and the particles in suspension.
Effect of Extraction Solvent on Oil and Bioactives
For this purpose, niger seeds were subjected to solvent extraction using solvents of different polarity, viz., hexane, petroleum ether, chloroform, acetone, methanol and ethanol. The oil content of niger seeds obtained after extraction with solvents of different polarities was in the range of 31.8–41.3 g/100 g.
This oil content of niger seeds was taken as the reference for comparing the oil yields by cold pressing, hexane and ethanol extractions done at pilot scale. Hexane is considered the most suitable solvent for oil extraction and has been used extensively by researchers for niger seed oil extraction [1–5, 8–11]. However, hexane usually
Comparing the extraction methods, chemical composition
The oil extract, 2 mL DPPH • solution and solvent (methanol or ethanol) were added to the test tube, so that the volume percent concentration of the oil extract in the sample was in the range of
Rice bran oil extracted using aqueous ethanol had 1.53% oryzanol and 769mg/kg tocotrienols, while absolute isopropanol extract had higher tocopherol content (98.10mg/kg) as compared to other solvents. The authors concluded that short chain alcohols could serve as better alternatives to hexane for solvent extraction of oil from oilseeds.
Physico-chemical characteristics of niger seed oil extracted
Bhatnagar and Krishna (2013) investigated the impact of ethanol, methanol, petroleum ether, chloroform, acetone, and hexane as extraction solvents on niger seed oil and bioactives and reported
For this purpose, niger seeds were subjected to solvent extraction using solvents of different polarity, viz., hexane, petroleum ether, chloroform, acetone, methanol and ethanol. The oil content
Extraction of sunflower oil using ethanol as solvent
Abstract. The ethanolic extraction of oil from sunflower collets was studied and compared with previous data where hexane was used as extraction solvent. First, the extractive power of ethanol was determined by Soxhlet. It gave a higher yield of extracted material, whose content of soluble hexane components (oil phase) was similar to that
The bioactives rich niger seed oil (BRNSO) obtained by extraction of niger seed with ethanol appeared to be a brownish thick liquid, while the bioactives concentrate from niger seed oilcake
