应用桃叶提取成分的水解产物—扁桃酸作体外杀精子实验,结果表明,扁桃酸具有较强的杀精效应,它使精子瞬间失活的最低有效浓度为0.8mg/ml～3.3mg/ml。并且应用弱酸杀精剂硼酸作比较,证明扁桃酸的杀精效力比硼酸高40倍。文中讨论了扁桃酸杀精子和杀滴虫的双重作用等问题。
The results showed that mandelic acid has strong spermicidal effect. The minimum effective concentration of mandelic acid inactivation is 0.8mg / ml ~ 3.3mg / ml . And the application of weak acid spermicidal boric acid comparison, proved spermic acid spermicidal effect than boric acid 40 times. The article discusses the dual effects of mandelic spermicides and trichomoniasis.
