Embodiment 1
[0145] 1000 g of fenugreek seeds with a moisture content below 7% were crushed in a roller flaker to a thickness of 5 mm. The crushed material was packed in a column with a bed height of 300mm. 5 L of hexane was passed through the fenugreek layer and the eluate (or effluent) collected from the bottom was recirculated through the fenugreek layer at 35 °C for a period of 10 h. After 10 h, the fenugreek layer was drained free of hexane. A solvent mixture (8 L) comprising isopropanol and water in a 4:1 ratio was passed through the layer by recirculating the eluent over a period of 8 h at 35 °C. After 8 h, the fenugreek bed was drained free of extract and all extract was collected. The collected extracts were concentrated in vacuo at 50 °C to a semi-solid mass. The concentrated pellet was redissolved in 5 L of deionized water to obtain a clear solution. The clear aqueous solution was slowly passed through a column containing 500 mL of strong acid cation exchange resin in macrop...
Embodiment 2
[0152] 1000 g of fenugreek seeds with a moisture content below 7% were crushed in a roller mill to a thickness of 5 mm. The crushed material was packed in a column with a bed height of 300 mm. 5 L of hexane was passed through the fenugreek layer and the eluate (or effluent) collected from the bottom was recirculated through the fenugreek layer at 35 °C for a period of 10 h. After 10 h, the fenugreek layer was drained free of hexane. A solvent mixture (8 L) comprising ethanol and water in a 4:1 ratio was passed through the layer by recirculating the eluent over a period of 8 h at 35 °C. After 8 h, the fenugreek bed was drained free of extract and all extract was collected. The collected extracts were concentrated in vacuo at 50°C to a semi-solid mass. The concentrated pellet was redissolved in 5 L of deionized water to obtain a clear solution. The clear aqueous solution was passed slowly over a period of 2 h through a column containing 500 mL of strong acid cation exchange ...
Embodiment 3
[0163] 1000 g of fenugreek seeds with a moisture content below 7% were crushed in a roller mill to a thickness of 6 mm. The crushed material was packed in a column with a bed height of 300mm. 5 L of hexane was passed through the fenugreek layer and the eluate (effluent) collected from the bottom was recirculated through the fenugreek layer at 35° C. for a period of 10 h. After 10 h, the fenugreek layer was drained free of hexane. A solvent mixture (8 L) comprising methanol and water in a 4:1 ratio was passed through this layer by recirculating the eluent over a period of 8 h at 35 °C. After 8 h, the fenugreek bed was drained free of extract and all extract was collected. The collected extracts were concentrated in vacuo at 50°C to a semi-solid mass. The concentrated pellet was redissolved in 5 L of deionized water to obtain a clear solution. The clear aqueous solution was passed slowly over a period of 2 h through a column containing 500 mL of strong acid cation exchange r...
