 of French Jasminum grandiflorum flowers showed maltol also to be a key odorant. Conventional hexane extraction produces absolutes which contain comparatively much lower amounts of maltol (which is significantly soluble in benzene and ethanol, but only poorly solubilized in hexane). Maltol could also be detected in the headspace of living jasmine flowers, contributing to the exquisite fragrance of natural jasmine. \\

+Using a total of 14 commercial samples of J. grandiflorum flower absolutes from India, Egypt and Morocco, a composition range of the absolutes was established for the 3 main J. grandiflorum flower grower countries. The 12 main ingredients in the absolutes showed great variations: Linalool (2.0-6.9%), benzyl acetate (15.7-27.6%), indole (0.3-4.9%), (Z)-jasmone (1.2-5.7%), benzyl benzoate (8.8-25.5%), isophytol (4.7-8.2%), geranyllinalool (1.2-3.8%), methyl linoleate (1.7-4.8%), (E)-phytol (4.8-16.8%), (E)-phytyl acetate (2.9-6.8%), squalene (1.7-4.9%), 2,3-epoxy squalene (0.7-11.0%). \\
