中文摘要: 建立不同品种荔枝核的定性分析方法，并探讨不同品种荔枝核间共有成分的变化规律。采用超高效液相色谱-串联四极杆-飞行时间质谱技术（ultra performance liquid chromatography tandem quadrupole time of flight mass spectrometry，UPLC-Q-TOF/MS）[ACQUITY UPLC HSS T3色谱柱；流动相以0.1%甲酸水溶液为A，以0.1%甲酸乙腈溶液为B，进行梯度洗脱；体积流量0.4 mL/min；柱温30℃，电喷雾离子源负离子模式（ESI-）]分析不同品种荔枝核中共有化学成分及含量高低。结果显示4种不同品种的荔枝核供试品共检识化合物99个，其中共有成分有9个，分别是维生素C、喇叭茶醇、去氢白菖蒲烯、别香橙烯、芍药二酮、缬氨酸、紫苏醇、环-（亮氨酸-异亮氨酸）、甲基麦冬黄烷酮B。
Abstract:The qualitative analysis method of different Litchi chinensis Soon.was established,and the change law of common components among different Litchi chinensis Soon.was discussed.Ultra performance liquid chromatography tandem quadrupole time of flight mass spectrometry（UPLC-Q-TOF/MS）[ACQUITY UPLC HSS T3 chromatographic column;the mobile phase was gradient eluted with 0.1%formic acid aqueous solution as a and 0.1%formic acid acetonitrile solution as B;volume flow:0.4 mL/min;the column temperature was 30 C,the electrospray ion source negative ion mode（ESI-）.]was used to analyze the common chemical components and content of Litchi chinensis Soon.of different varieties.The results showed that a total of 99 compounds were identified in the Litchi chinensis Soon.samples of four different varieties,included 9 components,namely vitamin C,horn tea alcohol,dehydrogenated gladiolene,allonerolene,paeoniflorin,valine,perilla alcohol,cyclo-(leucine isoleucine)and methyl ophiopogon flavanone B.
