Abstract

Object To stuay the quality of seedling leaves cultured from improved variety of Ginkgo biloba L.. Methods The content of terpene lactones in seedling leaves of G. biloba were determined by RP-HPLC-ELSD.Results The content of total terpene lactone producted in Jun. was more than that in Aug., and it was obviously lower in Nov.. The content of terpene lactone in grafting was more than that in seedling. The content of terpene lactone in male trees was more than that in female trees.Conclusion The content of the active components was related to the season of growth, age of tree, raising modes, environment of growth, geographic conditions and others. The evaluation of the content of the main active components BB and GB showed that the quality of seedling leaves cultured from improved variety of G. biloba in Jinagxi is better than that reported by literature.
