目的初步确定多伞阿魏Ferula ferulaeoides体外抗胃癌活性部位,并对其进行GC-MS指纹图谱研究。方法采用MTT法检测多伞阿魏不同提取物对胃癌细胞SGC-7901增殖的抑制作用;采用GC-MS、主成分分析对多伞阿魏体外抗胃癌活性部位指纹图谱进行研究。结果多伞阿魏氯仿提取部位对胃癌细胞SGC-7901增殖的抑制作用最强;建立了多伞阿魏体外抗胃癌活性部位GC-MS指纹图谱分析方法,确立了28个共有峰,与抑制胃癌细胞增殖作用有较强关系的11个共有峰,分别鉴定为峰1(3-甲氧基-1,2丙二醇)、2(右旋柠檬烯)、4(左旋乙酸龙脑酯)、6(乙酸松油酯)、7(2,6,10-三甲基-1,5,9-十一烷三烯)、8(α-柏木烯)、9(α-香柑油烯)、12(β-雪松烯)、21(8-表-γ-桉叶油醇)、22(γ-桉叶油醇)、23(茅苍术醇)。10批样品中共有峰成分占总成分的92%以上,其相似度达到0.9以上。结论初步确证了多伞阿魏氯仿提取部位具有抑制胃癌细胞SGC-7901增殖作用。建立的GC-MS指纹图谱方法快速、简便,具有良好的精密度、重复性、稳定性,可作为多伞阿魏活性部位的质量控制方法。

Objective To preliminarily ascertain the anti-gastric cancer active parts from the roots of Ferula ferulaeoide and to study its GC-MS fingerprint Methods The inhibitory effects of different extraction from the roots of F. ferulaeoide on the cell proliferation of SGC-7901 cells were determined with MTT colorimetric method. GC-MS fingerprint of in vitro anti-gastric cancer active parts from F. ferulaeoide was investigated and analyzed by GC-MS and principal component analysis（PCA）. Results The chloroform extract showed the best inhibition on the growth of SGC-7901 cells. The method on GC-MS fingerprint of in vitro anti-gastric cancer active parts from F. ferulaeoide was established, showing 28 common characteristic peaks. The PCA demonstrated that the common peaks 1, 2, 4, 6, 7, 8, 9, 12, 21, 22, and 23 were connected closely with the in vitro anti-gastric cancer activity, and the seven compounds were 3-methoxy-1,2-propanediol, D-limonene, L-borneol acetate, terpinyl acetate, 1,5,9-undecatriene, 2,6,10-trimethyl, α-cedrene, and a-bergsmotene, β-cedrene, 8-epi-γ-eudesmol, γ-eudesmol, hinesol. Totally 28 common compounds of 10 batches of samples accounted for over 92% of the volatile contents, and the similarity of the GC-MS fingerprints from the 10 batches of samples was over 0.90. Conclusion The chloroform extract from the roots of F. ferulaeoides with potential inhibitory effect on gastric cancer SGC-7901 cells is tentatively confirmed, and needs further to verify by animal cells in vivo. The method of GC-MS fingerprinting is rapid, simple, and accurate with good reproducibility and stability, and can be used to control the quality of active parts of F. ferulaeoides.
