摘  要:基于高效液相色谱检测方法,分析黑龙江省5个不同地区(方正、响水、查哈阳、五常、建三江)之间糙米中γ-谷维素总含量的差异,并且通过相关性分析得出稻米中阿魏酸酯单体间的变化关系,结果表明γ-谷维素总含量范围为10.88~33.53 mg/100 g,其中环木菠萝烯醇阿魏酸酯、24-亚甲基环木菠萝烯醇阿魏酸酯的含量最高,其次为菜油甾醇阿魏酸酯和β-谷甾醇阿魏酸酯,此外还发现不同成熟阶段的籽粒中γ-谷维素含量也有差别。在天然条件下γ-谷维素总含量发生显著变化,五常地区糙米中γ-谷维素平均含量最高,为(21.48±5.04)mg/100 g,响水地区均值最低,为(16.56±6.29)mg/100 g,并且多个阿魏酸酯单体间存在一定的线性关系。By high performance liquid chromatography(HPLC),we analyzed the difference in totalγ-oryzanol content in brown rice from five different rice-producing regions(Fangzheng,Xiangshui,Chahayang,Wuchang,and Jiansanjiang)in Heilongjiang province,and we determined the correlation between ferulic acid ester monomers in rice.The results showed that the total content ofγ-oryzanol changed from 10.88 to 33.53 mg/100 g,with cycloartenol ferulate,24-methylenecycloartanyl ferulate being the most abundant,followed by campesterol ferulate andβ-sitosterol ferulate.In addition,theγ-oryzanol content varied at different maturity stages.The total content ofγ-oryzanol significantly varied under natural conditions.The average content ofγ-oryzanol in brown rice from Wuchang was the highest,(21.48±5.04)mg/100 g,and the lowest value(16.56±6.29)mg/100 g was found in brown rice from Xiangshui.There was a linear relationship between the ferulic acid ester monomers.
