摘　　要：对同一品种、同一产地、同时采集的白笋和绿笋(食用部分),用氨基酸分析仪测定氨基酸含量。结果表明,含18种氨基酸。白笋除含天冬氨酸较多外,绿笋中其他各氨基酸含量均高于白笋。绿笋中氨基酸总量为19.93％,白笋为16.91％(以干重计)。用原子吸收分光光度法测定锌、铜、铁、锰,用DAN荧光法测定硒。结果表明,绿笋和白笋除铜含量相近外,其他元素含量绿笋都高于白笋。它们中的硒含量高于一般蔬菜。The white shoot and green shoot from the same breed of Asparagus were collected in the sane area at the same time. 1) The concentrations of Amino acids of the shoots were determined by amino acid high speed analysis instrument. The result showed that Asparagus contained 18 kinds of amino acids. All kines of amino acies of green shoot were more than those of white shoot except the aspartic. The concentrations of amino acids in green shoot and white shoot were 19. 93% and 16.91% (dry weight) reepectively. 2) The trace elements zinc copper, iron and manganese were measmed by atomic absorption spectrometer and selenium, by 2, 3-DAN fluorometry. The green shoot has as much copper as the white shoot, other trace element concentration in the green shoot war higher. The than in the white shret of selenium in both shoots were higher than in general vegetables.
