Abstract

DC60 (23/01/57) Method for preparing galangal extract containing phenylbutanoids by extracting galangal powder with isopropyl myristate using a ratio of 1 kilogram of galangal powder to 0.7 to 1.3 kilograms of isopropyl myristate, extracted using heat or microwave and using a repeated extraction method using galangal extract as a solvent for extracting new galangal powder, extracted at least 3 times to obtain galangal extract that has At least 3 types of phenylbutanoid active ingredients, namely (E)-1-(3,4- diethoxyphenyl) butadiene or DMPBD, (E)-4-(3,4- dimethoxyphenyl)but-3-en-1-ol or Compound D and (E)-4-(3,4- dimethoxyphenyl)but-3-en-1-yl acetate in a total amount of not less than 8 percent by weight. The method for preparing zingiber officinale extract containing phenylbutanoids is by extracting zingiber officinale powder with isopropyl myristate at a ratio of 1 kilogram of zingiber officinale powder to 0.7 to 1.3 kilograms of isopropyl myristate. The extraction is done by heating or microwave, and by repeating the extraction process using zingiber officinale extract as a solvent for extracting new zingiber officinale powder. The extraction is repeated at least 3 times to obtain a zingiber officinale extract containing: At least three phenylbutanoid compounds, namely (E)-1-(3,4- diethoxyphenyl) butadiene or DMPBD, (E)-4-(3,4- dimethoxyphenyl) buteth-3- n-1- ol or Compound D, and (E) (-4)(3,4- dimethoxyphenyl) buteth-3- n-1- yl acetate, in a total amount of not less than 8% weight by weight.

Claims (1)

Then filter the extract and extract with new galangal powder again. c. The first re-extraction: Extract new galangal fruit using the galangal extract obtained from the extraction in step b. as a solvent using a ratio of 1 kilogram of galangal powder to 0.7 to 1.3 kilograms of extract and use the method Extract in section B. Filter the extract and then extract the new galangal powder again. D. Second re-extracting: Extract the new galangal fruit using the herbal extract obtained from the extraction in section C as a solvent using the ratio of 1 kilogram of galangal powder to 0.7 to 1.3 kilograms of extract and use the extraction method in section B. Filter the extract and then extract the new galangal powder again. E. Third re-extracting: Extract the new galangal fruit using the herbal extract obtained from the extraction in section C as a solvent using the ratio of 1 kilogram of galangal powder to 0.7 to 1.3 kilograms of extract and use the extraction method in section B. Filter the extract and store in a tightly closed container to protect from light.
