Analysis and Evaluation on Idioplasmic Resource of Ginkgo biloba's Half-sib

Using total flavonoids,total terpene lactones,and total ginkgolic acids in leaves as index,HPLC method was applied to analyze and evaluate the quality of Idioplasmic Resource of Ginkgo biloba's half-sib.The results showed that the content of total flavonoids,total terpene lactones,and total ginkgolic acids in Ginkgo biloba leaves of half-sib was 3.644～8.119 mg/g,2.890～5.768 mg/g,and 6.070～20.148 mg/g,respectively.Synthetically,the quality of Idioplasmic Resources of Ginkgo biloba's half-sib had obvious differences.These results would provide a scientific basis for the selecting and breeding of superior varieties of Ginkgo biloba for leave production.
