摘　　要：研究了用甲醇－水作为流动相从μ－Ｂｏｎｄａｐａｋ Ｃ１８柱上分离和测定α－萘酚诸条件，建立了ＨＰＬＣ定量分析染发剂中α－萘酚的方法。借助于紫外检测器于波长２８５ｎｍ 处检测，其保留时间为９．３２ ｍ ｉｎ，标准曲线的线性范围为１０～２００ ｎｇ，其检出限为０．４５ ｎｇ（信噪比为２∶１），此方法准确、简单、快速、灵敏。Separation and determination of α naphthol were investigated with a μ bondapak C 18 column by elution with methanol water. A HPLC method for quantitative analysis of α naphthol in hair dye was developed. α Naphthol was detected at 285 nm with UV detector and the retention time was 9.35 min. The standard curve based on peak area is linear in the range of 10～200 ng. Detection limit is 0.45 ng(at a signal to noise ratio of 2∶1). This method is accurate、simple、rapid and sensitive.
