摘　　要：以氨基酸总量为测量指标,对我国不同地区银杏花粉的氨基酸总量进行分析测定,结果表明不同地区百年左右的银杏古树花粉的氨基酸总量差异较大,平均为23.43169g(以100g花粉为单位,其余同);银杏花粉中含有人体所必需的8种氨基酸,每100g花粉中8种必需氨基酸的平均含量为5.925484g,并且必需氨基酸在氨基酸总量中所占的比例较高;在这20个单株中,银杏花粉的氨基酸总量含量最高的是泰兴02为26.44422g,此外,重庆01、郯城01、通江02、嵩县02、西峡02、长兴04、奉化01、桂林09、天目01的氨基酸总量超过24g。The amino acid contents of pollen of aged male Ginkgo from different sources were determined in this study. The results showed that the amino acid content of Ginkgo pollens had significant difference among sources, the average amino acid content was 23.43 g/100 g. Ginkgo pollen contained 8 kinds of amino acid indispensable to human being,and their average content reached 5.925 g/100 g. Pollens from Tai-xing02 had the highest amino acid content of 26.44 g/100 g. Besides this,pollens from Chongqing 01 ,Tancheng 01, Tongjiang 02, Songxian 02, Xixia 02, Changxing 04, Fenghua 01, Guilin 09, Tianmu 01 had also high amino acid content （more than 24 g/100 g）, indicating the possibility of superior individual selection and pollen-producing plantation establishment.
