Embodiment 1
[0032] A production method of Hypericum perforatum extract, comprising the following steps:
[0033] (1) Raw material pretreatment: take the aboveground part of Hypericum perforatum, dry it until the water content is less than 10%, and then pretreat the product with an organic solvent after crushing; the particle size of the raw material after crushing is less than 2cm.
[0034] The specific steps of pretreatment are to add solvent oil to the raw material according to the ratio of 1:4, the temperature is 40°C, the extraction time is 3h, the solvent residue in the raw material is recovered after solid-liquid separation, and the solid raw material is used as a spare.
[0035] (2) Extraction: Add alkaline solvent to the pretreated raw material to adjust the pH value of the aqueous solution to 10 and extract with extractant. The weight ratio of the total solution of alkaline solvent and extractant to the raw material is 1:5, and the extractant accounts for the total solution. 60% ...
Embodiment 2
[0042] A production method of Hypericum perforatum extract, comprising the following steps:
[0043] (1) Raw material pretreatment: take the aboveground part of Hypericum perforatum, dry it until the water content is less than 10%, and then pretreat the product with an organic solvent after crushing; the particle size of the raw material after crushing is less than 2cm.
[0044] The specific steps of pretreatment are to add petroleum ether to the raw material at a ratio of 1:8, the temperature is 50°C, the extraction time is 2 hours, and the solvent residue in the raw material is recovered after solid-liquid separation, and the solid raw material is used as a spare.
[0045] (2) Extraction: Add alkaline solvent to the pretreated raw material to adjust the pH value of the aqueous solution to 13 and extract with the extractant. The weight ratio of the total solution of alkaline solvent and extractant to the raw material is 1:12, and the extractant accounts for the total solution....
