摘要:

本研究旨在分析假蒟提取物的活性成分并评价其体外抗氧化和抗炎活性。试验通过ABTS法检测3种假蒟提取物(石油醚、正丁醇及乙酸乙酯提取物)的抗氧化能力;采用LPS法建立猪小肠上皮细胞(IPEC-J2)体外炎症模型,用假蒟提取物预处理后,以ELISA法检测细胞上清液中肿瘤坏死因子(TNF-α)、白细胞介素-1(IL-1)和白细胞介素-6(IL-6)的含量。结果表明,3种假蒟提取物总抗氧化活性由大到小依次是假蒟正丁醇提取物、乙酸乙酯提取物、石油醚提取物(P<0.05),其中假蒟正丁醇提取物总生物碱、总酚含量最高,分别为2.81 mEq/100 g、161.82 mg/g。与空白组相比,LPS组IPEC-J2细胞的TNF-α(P<0.05)、IL-1(P>0.05)及IL-6(P<0.05)含量均升高;与LPS组相比,假蒟预处理组的这几种细胞因子含量均显著降低(P<0.05),由高到低依次为乙酸乙酯提取物>石油醚提取物>正丁醇提取物。综合试验结果,假蒟提取物具有一定的抗氧化作用,能影响IPEC-J2细胞炎性因子的分泌,抑制炎症反应。

Abstract:

This study was aimed to investigate the active ingredient and evaluate the antioxidant and anti-inflammatory activities of Piper sarmentosum Roxb. extracts in vitro.The antioxidant activities of three pepper extracts (petroleum ether,n-butanol and ethyl acetate) in vitro were determined by ABTS method.The inflammation model of IPEC-J2 cell was established with LPS in vitro,the levels of tumor necrosis factor (TNF-α),interleukin-1 (IL-1) and interleukin-6 (IL-6) were detected in cell supernatant by ELISA after pretreatment of Piper sarmentosum Roxb. extract.The results showed that the total antioxidant activity of Piper sarmentosum Roxb. extract in descending order were n-butanol extract,ethyl acetate extract and petroleum ether extract (P<0.05).The contents of total alkaloids and total phenols of Piper sarmentosum Roxb. n-butanol extract were the highest,which were 2.81 mEq/100 g and 161.82 mg/g,respectively.In anti-inflammatory experiments,compared with the blank group,the levels of TNF-α(P<0.05),IL-1(P>0.05) and IL-6 (P<0.05) in IPEC-J2 cells increased in LPS group,while compared with the Piper sarmentosum Roxb. pretreatment groups,these indexes in LPS group decreased significantly (P<0.05).The concentrations of cytokines from high to low were ethyl acetate extract,petroleum ether extract and n-butanol extract.In conclusion,the extract of Piper sarmentosum Roxb. had antioxidant activity,and it could affect the secretion of cytokines in IPEC-J2 cells and inhibit the inflammation.
