Abstract

From April to November,ginkgo leaves were selected and the flavonoids were analysed by using spectrophotometer.The results showed that the flavonoids content of ginkgo leaves reached to peak value in October.Moreover,the flavonoids content of the female leaves was higher than that of the male leaves.The water content of ginkgo leaves had no direct relation to the flavonoids content.
