摘要：
Disclosed is a method for preparing a soluble powder of an ethanolic extract of Hypericum perforatum. Provided is the method for preparing the soluble powder of the ethanolic extract of Hypericum perforatum, comprising: a step (a) of washing Hypericum perforatum a step (b) of inputting 70 to 80% ethanol (9 to 12 times with respect to the weight of Hypericum perforatum) and adding an alkaline agent to the washed Hypericum perforatum to prepare a solution with pH 8 to12, immersing the solution for 3 to 10 hours, conducting extraction of the immersed solution at a temperature of 85 to 120°C for 7 to 9 hours to separate a first extract from the Hypericum perforatum solution a step (c) of inputting 70 to 80 % ethanol (4 to 6 times with respect to the weight of Hypericum perforatum) to the washed Hypericum perforatum, conducting extraction of the solution at a temperature of 85 to 120°C for 3 to 5 hours to separate a second extract from the Hypericum perforatum solution a step (d) of mixing the first extract and the second extract to obtain a Hypericum perforatum extract and filtering the obtained Hypericum perforatum extract using a 0.5 to 2 &mum cartridge filter to prepare a Hypericum perforatum filtrate a step (e) of eliminating the ethanol from the Hypericum perforatum filtrate, vacuum concentrating at 25 to 35 brix to obtain a Hypericum perforatum concentrate a step (f) of adding an emulsion stabilizer to the obtained Hypericum perforatum concentrate to be stirred at a temperature of 55 to 75°C for 20 to 40 minutes to prepare a Hypericum perforatum mixture a step (g) of sterilizing the Hypericum perforatum mixture at a temperature 75 to 85°C for 10 to 20 minutes and a step (h) of spray drying the sterilized Hypericum perforatum mixture.COPYRIGHT KIPO 2016요한초 주정추출물의 수용화 분말 제조방법이 개시된다.
