摘要:

分析补骨脂醇提物(Psoraleae Fructus alcohol extract,PFE)化学成分并探讨其促黑色素生成作用机制。采用超高效液相色谱-四级杆飞行时间质谱(UPLC-Q-TOF-MS)对PFE化学成分进行鉴定;观察PFE对斑马鱼黑色素生成的影响;通过实时荧光定量聚合酶链式反应(quantitative real-time PCR,qRT-PCR)考察PFE、补骨脂素和异补骨脂素对小鼠黑色素瘤细胞B16-F10中酪氨酸酶(tyrosinase,Tyr)、酪氨酸酶相关蛋白1(Tyr-related protein 1,Tyrp1)和相关蛋白2(Tyr-related protein 2,Tyrp2)mRNA表达的影响。结果在PFE中共鉴定47个化学成分,其中黄酮类27个,香豆素类10个,单萜酚类8个和其他类2个;发现PFE作用斑马鱼18 hpf(受精后小时,hours post fertilization)后,能明显增加其体内黑色素水平;qRT-PCR结果显示,与对照组相比,PFE能显著增加TyrTyrp2 mRNA的表达,其他给药组均能不同程度地增加TyrTyrp1Tyrp2 mRNA的表达。

Abstract:

This study aims to analyze the chemical constituents of Psoraleae Fructus ethanol extract (PFE)and explore its mechanism of promoting melanin production.The chemical constituents of PFE were analyzed and identified by ultra performance liquid chromatography-quadrupole-time of flight-mass spectrometry (UPLC-Q-TOF-MS) technology.Zebrafish was used to investigate the effects of PEF on the melanogenesis.The regulation effects of PFE,psoralen and isopsoralen on the mRNA expression of tyrosinase (Tyr),Tyr-related protein 1(Tyrp1) and Tyr-related protein 2(Tyrp2) in mouse melanoma cells (B16-F10) were detected by real-time fluorescence quantitative PCR(qRT-PCR).A total of 47 compounds were identified in PFE extract,including 27 flavonoids,ten coumarins,eight monoterpenoids and two other compounds.Meanwhile,the Zebrafish experiment results showed that PFE could significantly increase the melanin level in zebrafish after 18 hpf (hours post fertilization).The results of qRT-PCR showed that compared with the control group,PFE could significantly increase the mRNA expression of Tyr and Tyrp2,while other groups exhibited up-regulation effects on the mRNA expression of Tyr,Tyrp1 and Tyrp2 in varying degrees.
