目的 观察元首口服液对O 2 的清除能力、抗衰老作用以及与卵磷脂的关系。方法 采用AP -TEMED比色测定法 ,测定O 2 含量 ,并计算O 2 清除率。结果 元首口服液几种型号 (1、2、3、4型 )对O 2 的清除率分别是 79.72 % ,2 9.40 % ,-195 .66% ,40 .66% ;O 2 浓度分别是 0 .791、2 .82 3、9.3 13、2 .0 77(μmol/L) ,有效成分卵磷脂含量分别是 2 5 .43、3 8.14、5 9.8、2 1.74(mmol/L)。结论 元首口服液对O 2 有明显的清除作用 ,其中 1型对O 2 清除率最强 ,清除率与含量成正比关系 (r =0 .93 45 ,P <0 .0 1)。
Objective To observe the O 2 scavenging ability, anti-aging effect and the relationship with lecithin in Yuanshou oral solution. Methods The AP-TEMED colorimetric method was used to determine the O 2 content and the O 2 clearance was calculated. Results The O 2 clearance rates of several models (1, 2, 3, and 4) were respectively 79.72%, 29.4%, -195.66%, and 40.66%; the O 2 concentrations were 0. 791, 2.82 3, 9.3 13, 2.07 (μmol/L), lecithin content of the active ingredient were 25.43, 3 8.14, 5 9.8, 2 1.74 (mmol/L), respectively. Conclusion Oral liquid of Yuanshou has obvious scavenging effect on O 2 , of which type 1 has the strongest clearance rate of O 2 , and the clearance rate is proportional to the content (r = 0.935 45, P <0.01).
