Embodiment 1
[0023] (1) Soak 50g of tobacco leaves in 95% ethanol for 2 hours, the ratio of solid to liquid is 1:10, extract in a water bath under reflux, the temperature of the water bath is 50°C, repeat the extraction twice, and then carry out vacuum distillation at 50°C to concentrate the extracted solution to brown Brown viscous liquid, 8.7 grams of extract was obtained after cooling.
[0024] (2) Dissolve the above-mentioned extract in water, filter it, and put it on a macroporous adsorption resin column HPD-100. The dosage is 20 times the mass of the extract. With a flow rate of 1.5BV / h, first wash 10 column volumes with water, and then 20 column volumes were eluted with 95% ethanol, and the eluate was collected, and the target segment I was concentrated under reduced pressure to 5.9 g
[0025] (3) After the target segment I is dissolved and filtered with ethanol, go to the gel chromatography column (filler is SephadexLH-20, and the consumption is 40 times of the target segment I qua...
Embodiment 2
[0044] (1) Soak 50 g of tobacco leaves in 95% ethanol for 2 hours, the ratio of solid to liquid is 1:8, and extract in a water bath under reflux at a temperature of 60° C., and repeat the extraction twice. Afterwards, the extracted solution was concentrated by distillation under reduced pressure at 50° C. to a brown viscous liquid, and 9.5 grams of extract was obtained after cooling.
[0045] (2) Dissolve the above-mentioned extract in water, filter it, put it on a macroporous adsorption resin column (HPD-100, the dosage is 10 times the mass of the extract), and elute 8 columns with water at a flow rate of 1.5BV / h volume, then 20 column volumes were eluted with 90% ethanol, and the eluate was collected, and the target segment I was concentrated under reduced pressure to 6.6g
[0046] (3) After the target segment I is dissolved and filtered with ethanol, the gel chromatographic column packing is (SephadexLH-20, the dosage is 30 times the mass of the target segment I), and the m...
Embodiment 3
[0051] (1) Soak 50g of tobacco leaves in 95% ethanol for 1h, the ratio of solid to liquid is 1:20, extract in a water bath under reflux, and the temperature of the water bath is 70°C, repeat the extraction twice, and then carry out vacuum distillation at 50°C to concentrate the extracted solution to brown Brown viscous liquid, 10.3 grams of extract was obtained after cooling.
[0052] (2) Dissolve the above-mentioned extract in water, filter it, put it on a macroporous adsorption resin column (HPD-100, the dosage is 15 times the mass of the extract), and elute 8 columns with water at a flow rate of 1.5BV / h volume, then 15 column volumes were eluted with 95% ethanol, and the eluate was collected, and the target segment I was concentrated under reduced pressure to 7.3g
[0053] (3) After dissolving and filtering the target segment I with ethanol, put it on a gel chromatographic column (SephadexLH-20, the dosage is 50 times the mass of the target segment I), the mobile phase is a...
