从红曲发酵液70%乙醇提取物的正丁醇萃取物中分离得到2种氮杂环丁烷型氨基酸，经光谱分析确定其结构分别为（+）-[1;（+）-monascumic acid]和（-）-syn-2-异丁基-4-甲基氮杂环丁烷-2，4-二羧酸[2;（-）-monascumic acid]。
The structures of two enantiomeric azetidine-type amino acids isolated from the n-butanol-soluble fraction of the 70% ethanol extract of red-mold rice fermented with Monascus pilosus were established to be (+)-[1; (+)-monascumic acid] and (-)-syn-2-isobutyl-4-methylazetidine-2,4-dicarboxylic acids [2; (-)-monascumic acid] based on spectroscopic methods.
