中文摘要:
      目的研究药用紫草高效液相色谱 -质谱 -多反应监测( UHPLC-QTRAP-MS/MS(MRM)特征轮廓谱与抗肿瘤活性的谱效关系,为明确紫草抗肿瘤作用物质基础提供依据。方法(2018年 5月至 2019年 12月,数据来源于嘉应学院医学院客家药用生物资源研究所)采用 UHPLC-QTRAP-MS/MS(MRM)技术建立药用紫草的特征轮廓谱,以 A549细胞抑制率为药效指标,采用偏最小二乘回归法分析其谱效关系,并对部分化合物进行活性验证。结果分析辨识了 24个与紫草抗肿瘤作用具有重要影响的成分,其作用相关性由高到低依次为峰 59、9、66、32、62、45、46、58、43、71、13、63、41、44、5、39、34、65、49、21、12、3、22和 60。验证结果显示紫草呋喃 A(19.86±0.55)μmol/L、紫草素( 1.10±0.05)μmol/L、紫草呋喃 E(22.60±0.92)μmol/L、乙酰紫草素(2.53±0.11)μmol/L、去氧紫草素( 5.43±0.24)μmol/L、异丁酰紫草素( 2.16±0.10)μmol/L、β,β-二甲基丙烯酰紫草素( 3.50±0.16) μmol/L和 α-甲基丁酰紫草素( 0.74±0.03)μmol/L对 A549细胞均有一定抑制作用,其 IC50值为 0.74~22.60 μmol/L,而阳性药紫杉醇的半数抑制浓度( IC50值)为( 3.45±0.16)μmol/L。结论紫草的抗肿瘤药效是多种成分共同作用的结果,该研究初步明确了紫草抗肿瘤药效物质基础,为紫草后续研究和开发提供了科学依据。
英文摘要:
      Objective To study the relationship between the UHPLC-QTRAP-MS/MS (MRM) characteristic chemical profile and an?ti-tumor effect, and to provide a basis for clarifying the material basis of anti-tumor effect of medicinal Zicao.Methods The characteristic chemical profile of medicinal Zicao from different habitats was established by UHPLC-QTRAP-MS/MS (MRM) technology (Data derived from the Hakka Institute of Medicinal Biological Resources, Jiaying University School of Medicine from May 2018 to December2019). The anti-tumor effect of inhibition to A549 cells was studied by MTT assays. The spectra-effect relationship was established by partial least squares regression analysis and validation test of anti-tumor in vitro was carried out.Results The anti-tumor effect of medicinal Zicao towards A549 cells was the combined action of 24 components, and the peaks of the major contribution to anti-tumor effect were as the following order: 59, 9, 66, 32, 62, 45, 46, 58, 43, 71, 13, 63, 41, 44, 5, 39, 34, 65, 49, 21, 12, 3, 22 and 60. The validation test showed that shikonofuran A (19.86±0.55) μmol/L, shikonin (1.10±0.05) μmol/L, shikonofuran E (22.60±0.92) μmol/L, acetylshikonin (2.53±0.11) μmol/L, deoxyshikonin (5.43±0.24) μmol/L, isobutyrylshikonin (2.16±0.10) μmol/L, β, β-dimethylacrylshikonin (3.50±0.16) μmol/L and α-methylbutyrylshikonin (0.74±0.03) μmol/L exhibited good inhibitory effects on A549 cells with inhibitory concentration 50 (IC50)values ranging from 0.74 to 22.60 μmol/L. The IC50 value of paclitaxel was (3.45±0.16) μmol/L.Conclusion The anti-tumor effect of medicinal Zicao is the result of combination of various components and the material basis of the antitumor effect has been revealed preliminarily. This study provides a reference for the further research and development of medicinal Zicao.
