摘　　要：为了认识大熊猫乳中氨基酸的组成特点,将大熊猫乳经6mol/L盐酸水解后,用高效液相色谱测定了不同泌乳阶段的20个乳样的氨基酸组成。结果显示,大熊猫初乳中含量最高的氨基酸是谷氨酸,约为5.2g/L;常乳和干乳期乳腺分泌物中含量最高的是脯氨酸;总氨基酸含量在泌乳2～10d内变化不明显,平均值约为34g/L;干乳期乳中氨基酸含量变化显著。The aim of present research is to investigate the amino acid composition of giant panda colostrum. Amino acid composition of 20 milk samples collected in different lactation periods was analyzed with high performance liquid chromatography using giant panda milk hydrolyzed by 6 mol/L HCl. The result showed that glutamate content was the highest in giant panda colostrum with average level of approximately 5.2 g/L, while in mature milk and mammary gland secretion in the dry period, proline content was the highest. No significant difference was observed in total amino acid concentration during day 2 to day 10 of lactation, with average level of about 34 g/L. Amino acid contents in the dry period exhibited significant alteration.
