Abstract: Norisoprenoids are the main components constituting grape varietal aroma. Norisoprenoid compounds make a great contribution to aroma quality of grapes and wines owing to their extremely low perception threshold and pleasant floral fruit characteristics. The present paper summarized the composition of norisoprenoids in grape berries，the representative aroma attribute，the norisoprenoid biosynthesis pathway and the involving key enzymes，as well as the factors affecting norisoprenoid accumulation. The future research focuses in this field are considered on the regulation of key enzymes，transcription factors，the effect of cultivation measures and so on.

Key words: grape, berry, norisoprenoid, biosynthesis, regulation
