一系列酚类衍生物被合成,采用傅里叶变换红外光谱仪(FTIR)、核磁共振波谱仪(NMR)和电喷雾质谱(ESI-MS)等波谱技术对其进行了结构表征,并对其进行美白活性测试。结果表明,HB-1(0.229±0.026)、HB-3a(0.829±0.135)、HB-3b(0.446&... 一系列酚类衍生物被合成,采用傅里叶变换红外光谱仪(FTIR)、核磁共振波谱仪(NMR)和电喷雾质谱(ESI-MS)等波谱技术对其进行了结构表征,并对其进行美白活性测试。结果表明,HB-1(0.229±0.026)、HB-3a(0.829±0.135)、HB-3b(0.446±0.047)、HMB-3a(1.747±0.215)、HMB-3b(1.307±0.058)和HPE-4b(2.501±0.261)对酪氨酸酶抑制作用明显优于阳性对照物α-熊果苷(3.60±0.029)。对显示出美白活性的化合物的抗氧化活性测试结果表明,HB-3b和HMB-3a抗氧化活性与阳性对照物槲皮素和番茄红素相当。因此该类化合物今后可作为美白剂和抗氧化剂加以开发利用。 展开更多

There are many studies that compare the quality and biological characteristics of honey with distinct geographical and botanical origins. However, the physico-chemical and biological properties of different types of honey in the same production regions are rarely mentioned.
