摘 要 目的:研究美洲大蠊提取物CⅡ-3与其体外抗肝癌活性的谱效关系,并初步明确其抗肝癌活性成分。方法:在已建立10
批 C Ⅱ -3 样 品 的 超 高 效 液 相 色 谱(UHPLC)指 纹 图 谱 的 基 础 上 ,借 助 超 高 效 液 相 色 谱 - 四 极 杆 - 飞 行 时 间 质 谱 联 用 法
(UHPLC-Q-TOF/MS),通过标准品和相关文献定性鉴定各色谱峰对应的化合物;以各批CⅡ-3样品对人肝癌细胞HepG2的半数
抑制浓度(IC50 )为抗肝癌活性指标,采用灰色关联度分析法(GRA)与正交偏最小二乘法(OPLS)建立并分析指纹图谱与抗肝癌活
性之间的谱效关系。结果:10 批 CⅡ-3 样品的 UHPLC 指纹谱图中有共有峰 25 个,指认出其中 10 个,分别为环(酪氨酸-脯氨酸)
(峰24)、环(甘氨酸-苯丙氨酸)(峰15)、次黄嘌呤(峰3)、腺嘌呤(峰7)、苯丙氨酸(峰10)、肌苷(峰11)、N-乙酰多巴胺(峰16)、环
(脯氨酸-丙氨酸)(峰 13)、2-羟基马尿酸(峰 22)、环(脯氨酸-丝氨酸)(峰 6)。10 批 CⅡ-3 样品对 HepG2 细胞的 IC50为 70.550~
200.303 μg/mL。25个共有峰中,以抗肝癌活性的GRA分析关联度(r)排序为峰20>23>24>15,且其r值均大于0.7;以OPLS分
析变量重要性投影(VIP)值排序为峰23>18>15>24>7>14>6>2>20,且VIP值均大于1,其中峰7、15、20、23、24的标准回归
系数均大于 0,峰 2、6、14、18 的标准回归系数均小于 0。联合分析显示,CⅡ-3 样品抗肝癌活性主要成分依次为峰 20>23>24>
15。结论:CⅡ-3中两个未知化合物(峰20、23)和环(酪氨酸-脯氨酸)(峰24)、环(甘氨酸-苯丙氨酸)(峰15)可能是其抗肝癌活性
的主要成分。

ABSTRACT OBJECTIVE:To study the spectrum-effect relationship of anti-hepatoma effect of CⅡ-3 extract from Periplaneta
americana,and to preliminarily clarify the anti-hepatoma active components of it. METHODS:Based on UHPLC fingerprints of
10 batches of CⅡ-3 samples,with the help of UHPLC-Q-TOF/MS,the compounds corresponding to each chromatographic peak
were identified qualitatively by standard substances and related literatures. Using the IC50 value of each batch of CⅡ-3 sample
against human hepatoma cells HepG2 as anti-hepatoma activity index, the spectrum-effect relationship of fingerprint and
anti-hepatoma effect was established and analyzed by the combination of grey relational analysis(GRA)and orthogonal partial least
squares(OPLS). RESULTS:There were 25 common peaks in UHPLC fingerprints of 10 batches of CⅡ-3 samples,and 10
chemical compounds were identified,which were cyclo-(Tyr-Pro)(peak 24),cyclo-(Gly-Phe)(peak 15),hypoxanthine(peak 3),
adenine(peak 7),phenylalanine(peak 10),inosine(peak 11),N-acetyldopamine(peak 16),cyclo-(Pro-Ala)(peak 13),2-hydroxy
propionyl(peak 22),cyclo-(Pro-Ser)(peak 6). The IC50 of 10 batches of CⅡ-3 samples to HepG2 cells was 70.550-200.303 μg/mL.
Among 25 common peaks,the order of GRA correlation(r)of anti-hepatoma activity was peak 20>23>24>15,all of r values
were greater than 0.7;the order of variable importance projection(VIP)of OPLS analysis was peak 23>18>15>24>7>14>6>
2>20,all of VIP values were greater than 1. The standard regression coefficients of peak 7,15,20,23,24 were all greater than
0;while the standard regression coefficients of peak 2,6,14,18 were all less than 0. Conjoint analysis shows that the order of
anti-hepatoma activity was peak 20>23>24>15.
