祛斑中药组方干预黑素合成的主效应中药剖析

摘要

目的 解析祛斑中药组方干预黑素合成的主效应中药.方法 采用3×2析因设计,以山楂、当归、山萸肉为考察因素,各设2水平,分别测定酪氨酸酶活性抑制率、多巴色素自动氧化生成黑素量、多巴自动氧化抑制率,并运用SPSS16.0软件辅助解析祛斑组方对干预黑素合成不同途径的主效应中药.结果 组方中山萸肉对酪氨酸酶活性具有显著抑制作用(P<0.05),山萸肉、当归对多巴色素自动氧化生成的黑素量具有极显著抑制作用(P<0.01),山萸肉、当归对多巴自动氧化具有显著抑制作用(P<0.05),山萸肉在组方中贡献最大.结论 山萸肉为组方中抑制酪氨酸酶活性、多巴色素自动氧化生成黑素量、多巴自动氧化的主效应中药.%Objective To investigate the major effective Chinese materia medica inQuban Prescription for intervention in melanin synthesis.Methods 3×2 factorial design was used. The factors of investigation were Crataegi Fructus, Angelicae Sinensis Radix and Corni Fructus. Tyrosinase activity, melanin generation and auto-oxidation of dopa were determinated respectively; and the major effective Chinese materia medica ofQuban Prescription for intervention in melanin synthesis was analyzed by SPSS16.0 software.Results Tyrosinase activity was remarkably inhibited by Corni Fructus (P<0.05). Melanin generation was remarkably inhibited by Corni Fructus and Angelicae Sinensis Radix (P<0.01). Auto-oxidation of dopa was remarkably inhibited by Corni Fructus and Angelicae Sinensis Radix (P<0.05). Corni Fructus was in an absolute leading position.ConclusionCorni Fructus is the major effective Chinese materia medica in inhibiting tyrosinase activity, melanin generation and auto-oxidation of dopa in the prescription.
