Applying grading methods of synthesizing multiple guidelines to optimizing alcohol-steam processing technology from Ploygonatum odordatum
In order to improve the quality of processed products and application in the field of medicine or healthy food,we optimized the alcohol-steam processing technology of Ploygonatum odordatum.On the basis of the content and antioxidant activity of the saponins,polysaccharose,total flavonoids,ethanol extracts and water extracts,the best extracted technology was generated using orthogonal test coupled with grading methods of synthesizing multiple guidelines.The results showed that the optimal technology was 2 h alcohol-moistening,5 times the amount of solvent,60 ℃ for 1 h,and the material-liquid ratio was the most significant influence factor.This method had effectively raised the utility value of Ploygonatum odordatum.[Ch,1 fig.6 tab.31 ref.]
