摘　　要：目的:建立青稞红曲质量中氨基酸的参考指标,并为青稞红曲的质量标准提供科学依据。方法:采用相应前处理方法、氨基酸自动分析仪、高效液相分析仪,进行氨基酸检测及对比实验。结果:在18种氨基酸含量中,青稞的总氨基酸含量为7.42%,青稞红曲的总氨基酸含量为11.38%,红曲米的总氨基酸含量为11.11%;青稞红曲与大米红曲在总氨基酸含量上接近,在与谷物青稞相比,总氨基酸含量提高53.37%;青稞红曲与市售红曲的功效成分γ-氨基丁酸、Monacolin K的测定对比中,青稞红曲的γ-氨基丁酸、Monacolin K平均含量在2.33、4.34 mg/g,高于市售红曲的含量。结论:青稞红曲的总氨基酸含量为11.4%,γ-氨基丁酸平均含量为2.33 mg/g,Monacolin K平均含量为4.34 mg/g,可以为青稞红曲的质量标准研究提供参考数据。Objective： To establish highland barley Monascus quality amino acids reference indicators, and to provide a scientific basis for the highland barley Monascus quality standard. Method： Using the appropriate pre-treatment methods, automatic amino acid analyzer, high performance liquid analyzers, amino acid detection and comparative experiments. Results： 18 kinds of amino acids in the highland barley total amino acid content of 7.42%, the total amino acid content of the highland barley Monascus is 11.38%, 11.11% of the total amino acid content of red kojic rice; highland barley Monascus, red kojic rice in close to the amino acid content, highland barley and grain compared to the 53.37% increase in total amino acid contcnt; highland barley Monascus the effectiveness of the composition of red kojic rice γ-aminobutyric acid Monacolin K determination contrast, highland barley Monascus γ-aminobutyricthe average content of 2.33 mg/g, Monacolin K average content of 4.34 mg/g, higher than the content of the red kojic rice.Conclusion： The total amino acid content of highland barley Monascus 11.4%, the average content of ^-aminobutyric acid to 2.33 mg/g, average Monacolin K content to 4.34 mg/g, can provide a reference for the of highland barley Monascus quality standard research data.
