在分析、比较了多种中草药提取物对脂肪酶的激活效率的基础上 ,作者用温和的生物工程手段 ,从中药紫花地丁中纯化得到高效的脂肪酶激活剂 ,当浓度达到 16 6 .6 7mg/ml,酶浓度为 40 mg/m l时 ,激活效率可达2 80 % .研究表明 ,此激活剂对脂酶具有竞争性与反竞争性的混合激活效应 ,并且该激活剂具有热稳定性 .在 p H =7.0的反应条件下 ,激活效率达到最高 Based on the analysis of the efficiency of lipase activation by a variety of herbal extracts, the authors purified the lipase activator from Vitex glabra by gentle bioengineering. When the concentration reached 16.6.6 7mg / ml, the enzyme concentration of 40 mg / ml, the activation efficiency of up to 2 80% .Studies show that this activator of lipase has a competitive and anti-competitive mixed activation effect, and the activator has thermal stability At p H = 7.0, the activation efficiency is maximized
