【摘要】 为了解薏苡非种仁部位中氨基酸的含量,为薏苡非种仁部位的质量评价与优质药材的选择和培育提供依据,采用柱前衍生化RP-HPLC法,对贵州和云南不同采收期、不同产地薏苡非种仁部位的氨基酸含量进行了测定。结果表明:9种薏苡非种仁部位中均含有16种氨基酸,其中包含人体必需的7种氨基酸。内种皮中氨基酸总量和人体必需的7种氨基酸总量最高,为11 342~13 981 mg/100g和3 553~4 260mg/100g;其次为薏苡的根和外种皮,分别为4 263~6 753mg/100g、1 373~1 683mg/100g和1 537~6 851mg/100g、506~1 751mg/100g。因此,在薏苡非种仁部位的开发中,可选择贮藏时间较短的内种皮进行综合利用。更多还原

【Abstract】 In order to understand the amino acids content in Coix non kernel parts,and provide a reference for quality evaluation and selection and breeding of high-quality medicinal materials,the amino acids in non kernel parts of Coix,collected in Guizhou and Yunnan with different harvest time and origin, were determined by pre-column derivatization for RP-HPLC.The results showed that nine Coixnon kernel parts contained 16kinds of amino acids,which contained seven kinds of essential amino acids.Overall, within the Coixendopleura the total amino acids and essential amino acids were the highest,11 342~ 13 981mg/100g and 3 553~4 260mg/100g respectively,followed by Coixroots and testa,4 263~6 753 mg/100g and 1 373~1 683mg/100g in roots,1 537~6 851mg/100gand 506~1 751mg/100g in testa. Consequently,endopleura with short storage time could be comprehensively utilized in the exploitation of non kernel parts of Coix.更多还原
