Embodiment 1
[0030] Such as figure 1 Shown, a kind of method for simultaneously extracting solanesol, cembrane diterpene, vitamin E, phytosterol from tobacco, specifically comprises the steps:
[0031] (1) Extraction: Take the prepared low-grade flue-cured tobacco leaves, dry them at 60°C, crush them, weigh 200g of the crushed tobacco powder, use n-hexane as the extractant, the ratio of solid to liquid is 1:10, ultrasonically extract at 45°C for 30min, centrifuge Or filter, and the residue is washed twice with the extract (the ratio of solid to liquid twice is 1:8, 1:6 respectively), the extract is combined, concentrated under reduced pressure and the solvent is recovered to obtain 12.5g extract;
[0032] (2) Saponification: Add 120mL of 95% ethanol and 2g of sodium hydroxide to the extract obtained in the above steps, and heat and reflux saponification at 60°C for 1h. After the saponification is completed, adjust the pH value to neutral and concentrate to remove the organic solvent. Add ...
Embodiment 2
[0038] Such as figure 1 Shown, a kind of method for simultaneously extracting solanesol, cembrane diterpene, vitamin E, phytosterol from tobacco, specifically comprises the steps:
[0039] (1) Extraction: take the unsuitable lower or upper part of flue-cured tobacco in the mature stage of the field, dry it at 60° C., grind it, weigh 200 g of the ground tobacco powder, use petroleum ether as the extractant, and the remaining steps are the same as in Example 1;
[0040] (2) Saponification: the used extraction solvent for extracting the fat-soluble active ingredient after saponification is completed in this saponification process is sherwood oil, and all the other steps are with implementation example 1.
[0041] Following separation steps are the same as implementation example 1.
Embodiment 3
[0043] Such as figure 1 Shown, a kind of method for simultaneously extracting solanesol, cembrane diterpene, vitamin E, phytosterol from tobacco, specifically comprises the steps:
[0044] (1) Extraction: take mature sun-cured tobacco leaves, dry at 60° C., pulverize, weigh 200 g of pulverized tobacco dust, and use petroleum ether as the extractant. The following steps are the same as in Example 1.
