银杏花粉化学成分初步研究
A Preliminary Study on Ginkgo biloba Pollens
【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%。
【Abstract】 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%.
