摘要
Gardenia jasminoides is an important ornamental greening plant with medicinal and edible values. This study investigated volatile constituents, alcoholic components and physiological activities on flowers of G. jasminoides Ellis and its variety. It was found that a total of 56 volatile components were identified, and terpenoids and esters were the main compounds to distinguish these species. Furthermore, the alcohol-soluble extracts of G. jasminoides flowers have the high contents of total phenols and total flavonoids, with potential antioxidant and hypoglycemic activities. In addition, nine compounds were identified, whose distribution in petals and stamens of G. jasminoides were significantly dissimilar. The contents of flavonoids and phenolics were stable after blanching confirmed by our findings, while iridoids were remarkably higher after freeze-drying (FD) and hot-air drying (HD). This research provides evidences that the fragrance, active components and activity of flowers of these species were affected by species, flower parts and processing methods.
