摘　　要：目的:研究何首乌生品及不同炮制品的抗氧化活性。方法:采用化学发光法对何首乌生品及不同炮制品清除自由基的能力进行比较。结果:以发光抑制率表示超氧化物歧化酶的活性,结果发光抑制率从高到低依次为生品、黑豆制品、清蒸品、黑豆加酒制品,即何首乌生品的抗氧化活性最高。结论:如果能采取一种炮制方法仅破坏何首乌的泻下成分而保留其有效成分,则能增强其补益效果,充分发挥其抗衰老作用。OBJECTIVE:To study the antioxidation activity of different processed products of polygonum multiflorum thunb and its crude.METHODS:The capabilities of different processed products of polygonum multiflorum thunb and its crude in eliminating free radical were studied and compared by chemical luminescent technique.RESULTS:The luminescent inhibiˉtion ratio was used to represent the activity of superoxide dismutase(SOD),the result showed that the ratio of luminescent inˉhibition of the crude sample of polygonum multiflorum thunb ranked the top,i.e.the crud sample had the highest antioxidation activity,then the black bean product,product that steamed in clear soup and that steamed in black bean alcohol soluˉtion.CONCLUSION:If one can develop a preparation method in which only the purgative component of polygonum multifloˉrum thunb were destroyed while the effective components remained,the tonification function of which can be enhanced and the anti-aging effect of which can be brought into full play.
