Method of preparing lyophilizate of Taheebo alcohol extract
The present invention relates to a method of preparing a lyophilizate of a Taheebo alcohol extract, including: (a) extracting Taheebo with an alcohol and concentrating an extract; and (b) lyophilizing the alcohol-extracted and concentrated Taheebo, and a composition for the treatment, prevention or amelioration of an inflammatory disease including a lyophilizate of a Taheebo alcohol extract prepared therefrom.
1. A method of preparing an anti-inflammatory Taheebo extract comprising veratric acid, said method comprising:
(a) extracting Taheebo with an alcohol comprising ethanol in a range of 70 to 90 (v/v) %; and
(b) lyophilizing said alcohol extract solution to produce said anti-inflammatory Taheebo extract comprising a therapeutically effective amount of veratric acid.
2. The method of claim 1 , wherein, in Step (a), the extracting is performed at a temperature of 40 to 80° C. for 3 to 10 hours.
3. The method of claim 1 , wherein said step of lyophilizing is performed at a temperature of −30 to −50° C. for 48 to 168 hours.
4. The method of claim 1 , wherein the lyophilizate of a Taheebo alcohol extract has an inhibitory effect of nitric oxide synthesis.
