【中文摘要】 探討用超聲提取法提取樺褐孔菌中樺褐孔菌多糖的工藝條件及樺褐孔菌多糖對肝癌SMMC7721細胞株的抗增殖作用。設計正交實驗,對樺褐孔菌的超聲提取工藝進行研究,并用MTT比色法研究樺褐孔菌多糖對肝癌SMMC7721細胞株的抗增殖作用。樺褐孔菌多糖超聲提取的最佳工藝條件為95℃、15倍水、20kHz、超聲60min,樺褐孔菌多糖在1.0￣16.0μg/mL范圍內對肝癌SMMC7721細胞株的增殖均有抑制作用,且表現出濃度相關性。

【英文摘要】 OBJECTIVE To investigate the optimal purified protocol of extracting Inonotus obliquus polysaccharide using ultrasonication and the effect of the extractions from Inonotus obliquus polysaccharide on anti-proliferation for SMMC7721 cells of liver cancer.METHORD The method of orthogonal analysis was used to extract Inonotus obliquus polysaccharid with ultrasonication,The methods of MTT was used to study the anti-proliferative effect of the polysaccharide on the hepatocarcinoma SMMC7721cells.RESULT The best condition used in the course of extraction of Inonotus obliquus polysaccharide was: the temperature was 95℃,the volume of water was 15 times,the frequency of ultrasonication on the extraction was 20kHz,the optimal duration of extraction was 60min.The Inonotus obliquus polysaccharide had the inhibiting action on SMMC7721 cells of liver cancer line in the concentration of 1.016.0ug/mL by means of MTT assay,and exhibited a strong dependence on concentration.
