Embodiment 1
[0027] (1) Grind hyssop into powder and pass through a 40-mesh sieve, mix hyssop powder under the net, 30% alcohol solution by volume, and sodium chloride at a mass ratio of 1:10:0.05, and reflux for 2 hours Finally, to obtain the reflux extract, add 5% tartaric acid aqueous solution into the reflux extract by mass percentage, stir while adding, adjust the pH to 5, and filter with a 0.45 μm membrane, the obtained filtrate is the crude extract of hyssopus, and the filter residue abandoned.
[0028] (2) the hyssopus crude extract in step (1) is transferred in the material tank of molecular distillation equipment, at scraper speed 300r / min, vacuum tightness 150Pa, distillation temperature 40 ℃, feed rate 1ml / min, Molecular distillation was carried out under the condition of condensation temperature of 6°C to obtain light components and heavy components, and the light components were discarded.
[0029] (3) Add a butyl acetate solvent whose volume is 1 / 3 times its volume to the h...
