摘　　要：为建立精准的蜂王浆新鲜度检测方法,利用超高效液相色谱-串联四极杆飞行时间质谱(ultra-high performance liquid chromatography-tandem quadrupole-time-of-flight mass spectrometry,UPLC-Q-TOF/MS)对经胰蛋白酶酶解的蜂王浆中王浆主蛋白(major royal jelly proteins,MRJPs)进行定性分析,并通过蛋白质组学分析平台比对,鉴定出8种王浆主蛋白(MRJP1~7和MRJP9)的一级序列数据,然后按同时具备高易酶解性与酶解后高稳定性的标准筛选得到3个特异性标志多肽,包括MRJP1多肽YNGVPSSLNVISK、MRJP2多肽TLQMIAGMK、MRJP3多肽LTVAGESFTVK。分别合成MRJP1~3的3条特异性标志多肽标准品及其同位素标志肽,建立蜂王浆中MRJP1~3的超高效液相色谱-串联三重四极杆质谱(ultra-high performance liquid chromatography-triple quadrupole tandem mass spectrometry,UPLC-TQMS)定量检测方法。采用UPLC-TQMS分别检测蜂王浆样品中MRJP1~3含量发现,MRJP1多肽在10~1 600 ng/mL范围内具有良好的线性关系,MRJP2和MRJP3多肽在10~600 ng/mL范围内均具有良好的线性关系,决定系数(R~2)均大于0.99。最后,通过分析蜂王浆中MRJP1~3随加温老化时间的降解程度,证实MRJP1~3的降解率均与老化时间(40℃)呈正相关(R~2>0.9)。说明本研究所建立的MRJP1~3检测方法具有高度特异性,可为蜂王浆质量评价提供技术支撑。In order to establish an accurate detection method for royal jelly freshness,the major royal jelly proteins (MRJPs) in royal jelly by trypsin enzymatic hydrolysis were identified by ultra-high performance liquid chromatography-tandem quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF/MS).The primary sequence data of eight MRJPs (MRJP1-7 and MRJP9) were identified by proteomics analysis platform.Then three specific marker polypeptides were obtained according to the criteria of highly easy enzymolysis and high stability,including YNGVPSSLNVISK (MRJP1),TLQMIAGMK (MRJP2),and LTVAGESFTVK (MRJP3).The three specific marker polypeptides of MRJP1-3 and their isotopic marker peptides were synthesized respectively,and an ultra-high performance liquid chromatography-triple quadrupole tandem mass spectrometry(UPLC-TQMS) method for the quantitative detection of MRJP1-3 in royal jelly was established.The results showed that the MRJP1 polypeptide had a good linear relationship in the range of 10-1 600 ng/mL,and MRJP2and MRJP3 polypeptides had a good linear relationship in the range of 10-600 ng/mL,and the correlations of determination (R~2) were all more than 0.99.Finally,by analyzing the degradation degrees of MRJP1-3 in royal jelly with the aging time,it was confirmed that the degradation rates of MRJP1-3 were all positively correlated with the aging time at 40℃(R~2>0.9).It is indicated that the MRJP1-3 detection method established in this study is highly specific,which provides technical support for the quality evaluation of royal jelly.
