摘　　要：对银杏花粉的一般性状和化学成分进行了初步研究，内容包括花粉堆积密度，每克的花粉数目，孢粉素含量，黄酮含量及甙元组成、脂肪酸组成。结果表明，花粉中总黄酮甙含量为０９５％，主要甙元为山柰酚，脂肪酸组成为棕榈酸２１７％，硬脂酸７５％，油酸２７７％，亚油酸６０％，亚麻酸１６２％，花粉壁主要组成孢粉素含量为１５％。A preliminary study was made on Ginkgo biloba pollens, including general property (stacked density, pollen numbers per gram, average diameter) and chemical components (sporopollenin, flavomoid and composition of fatty acids). The results showed that the content of general flavonoid glycoside was 0.95% in pollens, the main flavonoid aglycone was kaempferol. The composition of fatty acids was 160(217%),180(75%),180(27.7%),182(6.0%) and 183(16.2%). The content of sporopollenin, main component of pollenwall, was about 15%.
