结晶紫法测定OH自由基清除能力的原理
结晶紫法测定OH自由基清除能力的原理是沙棘果粉对DPPH自由基、超氧阴离子O2-、羟基自由基（·OH）、过氧化氢H2O2有较强的清除或抑制作用，且显示较好的量效关系。绛旓細缁撴櫠绱硶娴嬪畾OH鑷敱鍩烘竻闄よ兘鍔涘熀鏈師鐞嗘槸寮曡█缇熻嚜鐢卞熀鏄竴绉嶆哀鍖栬兘鍔涘緢寮虹殑鑷敱鍩锛屽鏄撳湴姘у寲鍚勭鏈夋満鐗╁拰鏃犳満鐗╋紝鏄犳垚鐢熺墿缁勭粐鑴傝川杩囨哀鍖栥佹牳閰告柇瑁傘佽泲鐧借川鍜屽绯栧垎瑙ｇ殑閲嶈娲汇侶2O鍙戠敓Fenton鍙嶅簲浜х敓OH锛孫H瀹规槗杩涙敾楂樼數瀛愪簯瀵嗗害鐐癸紝浼氫笌缁撴櫠绱腑鍏锋湁楂樼數瀛愪簯瀵嗗害鐨勫熀鍥㈠彂鐢熶翰鐢靛姞鎴愬弽搴 ...
