| titleOfInvention | The method that algistatic activity ingredient prepares algae-inhibiting agent is extracted from grape pip |
| abstract | A method of algistatic activity ingredient, which is extracted, from grape pip prepares algae-inhibiting agent, steps are as follows: (1) by pretreated grape pip and acetone soln according to quality: volume ratio is the ratio mixing of 1:10~30(kg:L), is stood to promote active constituent contained in grape pip to be fully dissolved out；Then residue of grape seeds is removed, grape pip leaching liquor is obtained；(2) obtained grape pip leaching liquor is depressurized, concentration, recycles acetone, obtain the aqueous solution of grape pip extract, adjustment aqueous solution volume to former acetone soln volume；(3) aqueous solution of the grape pip extract sodium hydroxide solution of 2mol/L is adjusted into pH to 12, after n-hexane extraction 3 times, again by the aqueous solution salt acid for adjusting pH of 2mol/L to 5, it is extracted with ethyl acetate 3 times, it collects upper layer ethyl acetate portion and merges 3 acetic acid ethyl acetate extracts, revolving recycling ethyl acetate, obtains grape pip medicinal extract；(4) final algae-inhibiting agent will be obtained after grape pip medicinal extract dimethyl sulfoxide hydrotropy. |
