Condition Optimization of Semi-bionic Extraction for Gardenia Jasminoides Ellis by Uniform Design / 中国药师

ABSTRACT

Objective: To optimize the extraction conditions of semi-bionic extraction for Gardenia jasminoides Ellis. Methods:The best extraction conditions of the semi-bionic extraction for Gardenia jasminoides Ellis was screened by uniform design with yield of geniposide, total iridoid glycosides and dry extract as the indices. Results:The optimal conditions were as followsthe pH value of wa-ter for the lst, 2nd and 3rd decoction was 2. 0, 6. 5 and 9. 0, respectively, and the extraction time was 2. 0, 1. 0 and 1. 0h according-ly. Conclusion:The optimized extraction conditions by uniform design is scientific and reasonable.
