Bee pollen, which is known as a "full-nutrient food", has outstanding anti-tyrosinase activity. However, the chemical components contributing to this activity remain unknown. To comprehensively elucidate the chemical components of bee pollen inhibiting tyrosinase, we performed the anti-tyrosinase activity evaluation of bee pollen extract (BPE) of eight species, metabolomic analysis of chemical composition, multivariate statistical analysis and correlation analysis. The results revealed that the anti-tyrosinase activity of eight BPEs was significantly different (p < 0.05), with IC value ranging from 10.08 to 408.81 μg/mL. A total of 725 metabolites were detected from these BPEs, and 40 differential metabolites were identified, all of which were phenolamides. All these phenolamides were positively correlated with the anti-tyrosinase activity, among which 26 phenolamides (21 spermidine derivatives and five spermine derivatives) showed particularly high correlations (r > 0.7). This is the first report to reveal the main contributor to the anti-tyrosinase activity of bee pollen.
蜂花粉,被誉为“全营养食品”,具有出色的酪氨酸酶抑制活性。然而,其具有该活性的化学组成部分尚不清楚。为了全面阐明抑制酪氨酸酶的蜂花粉的化学组成,我们对 8 种蜂花粉提取物(BPE)进行了酪氨酸酶抑制活性评价、化学成分的代谢组学分析、多元统计分析和相关分析。结果表明,8 种 BPE 的酪氨酸酶抑制活性差异显著(p<0.05),IC 值范围为 10.08 至 408.81μg/mL。从这些 BPE 中检测到 725 种代谢物,鉴定出 40 种差异代谢物,均为酚酰胺。所有这些酚酰胺与酪氨酸酶抑制活性呈正相关,其中 26 种酚酰胺(21 种亚精胺衍生物和 5 种精胺衍生物)相关性特别高(r>0.7)。这是首次报道揭示了蜂花粉抑制酪氨酸酶活性的主要贡献者。
