Problems solved by technology

During this process, valerian triesters are destroyed; while β-cyclodextrin can be used to embed volatile oil, but it needs to be processed by grinding (or other methods), filtering, vacuum drying, etc. There are many processes and a long cycle

Embodiment 1

[0011] Such as figure 1 As shown, firstly, 300 kg of Xiecao was taken, soaked with 2 times the amount of 95% ethanol, then placed in a multi-functional traditional Chinese medicine extraction tank, extracted by percolation with 10 times the amount of 95% ethanol, collected the percolation liquid, and reduced it at 45°C. Recover ethanol under pressure to obtain about 16 kg of oil, add 5 times the amount of water to the dregs, heat to boiling, extract for 3 hours, collect the water extract, concentrate under reduced pressure to 9-10 Baume, and obtain a water-extraction concentrate. Take about 30kg of water-soluble capsule material (such as a kind of denatured cornstarch), put it in a mixing tank, add 300kg of water to heat and stir to dissolve, cool to room temperature, add all the above-mentioned oily substances, stir well, then add water to extract the concentrate, stir to mix Uniform, spray-dried to obtain about 58kg of valerian extract. After measurement, the transfer rate ...

Embodiment 2

[0013] Such as figure 1 As shown, first take 300kg of valerian root, soak it with 2 times the amount of 95% ethanol, then place it in a multifunctional traditional Chinese medicine extraction tank, use 13 times the amount of 95% ethanol for percolation extraction, collect the percolation liquid, and depressurize at 40°C Recover ethanol to obtain about 18 kg of oil; add 3 times the amount of water to the dregs, heat to boil, extract for 1 hour, collect the water extract, concentrate under reduced pressure to 5-6 Baume, and obtain a water-extraction concentrate. Take about 19KG of water-soluble capsule material (such as a kind of denatured cornstarch), put it in a stirring tank, add 150kg of water to heat and stir to dissolve, and cool to room temperature; Uniform, spray-dried to obtain about 61kg of valerian extract. After measurement, the transfer rate of volatile oil reaches 69.0%, the transfer rate of valerian triesters is more than 72.0%, and the encapsulation and embeddin...

Abstract

The preparation method of valerian root extract includes the following steps: coarse breaking fresh or dried valerian root; using 95% ethyl alcohol to make diacolation extraction; collecting diacolation liquor; low-temp. reduced pressure recovering ethyl alcohol; using water and heating to extract residuum to obtain aqueous extract, reduced pressure concentrating; using water soluble capsule material, adding proper quantity of water, heating, stirring and dissolving, cooling to room temp., adding said ethyl alcohol extract concentrate, fully stirring, more adding water extract concentrate, uniformly mixing, spraying and granulating, drying to obtain the invented valerian root extract. As compared with existent technology it features high effective component conversion rate, fire granular product, good water solubility, stable product quality and simple process.

Description

technical field [0001] The invention relates to a preparation method of valerian root extract. Background technique [0002] Valerian has a calming and tranquilizing effect, can strengthen the inhibition process of the cerebral cortex, and reduce reflex excitability. The valerian triesters isolated from valerian have stabilizing effects on frogs, mice, and rabbits: valerian volatile oil can make mice quiet and prolong sleep time; valerian water extract also has similar activity. The sedative effect of valerian is related to the extraction of volatile oil, valerian triesters, and water. [0003] Because valerian triesters are easy to degrade and valerian volatile oil is easy to volatilize, conventional preparation methods cannot guarantee its stability. The essential oil is usually extracted by steam distillation. During this process, the valerian triesters are destroyed; while the β-cyclodextrin can be used to embed the volatile oil, but it needs to be processed by grindi...
