海带ACE酶抑制剂的浸提工艺研究
Study on extraction process of ACE inhibitor from kelp
摘要
Abstract
RP-HPLC was used to evaluate the inhibitory activity of water extract from kelp to angiotensin converting enzyme（ACE） ,which could reveal its antihypertensive activity.Effects of three single factors including solid-liquid ratio,extraction time and temperature on activities of kelp extract were investigated by single factor and orthogonal test.The results showed that the optimum technological conditions were solid-liquid ratio 1 ：200,30℃ in the water immersion for 24h.Inhibition rates of water extract from root, middle and rhizoid of kelp to ACE were 66.？% ,22.8% and 80.？%,respectively.Water extract from rhizoid of kelp was the most active part.The results of analysis on ingredients showed that water extract from rhizoid of kelp contained the lowest content of protein, iodine, total sugar and fucoidan, and the highest content of amino acid, calcium ion and sulfate radical.The contents of natrium, magnesium and kalium of different parts of kelp had no significant difference.关键词
