摘要/Abstract

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。

Abstract: By high performance liquid chromatography (HPLC), we analyzed the difference in total γ-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 of γ-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 and β-sitosterol ferulate. In addition, the γ-oryzanol content varied at different maturity stages. The total content of γ-oryzanol significantly varied under natural conditions. The average content of γ-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.

Key words: brown rice; γ-oryzanol; ferulic acid ester; high performance liquid chromatography
