Abstract
 A qualitative and quantitative study on the distribution of iridoids, flavonoids and mannitol in 5 of Jasmins has been carried out. The over ground parts of the plants under investigation are free from flavonoidal aglycones. They contain flavonol glycosides but no flavones. Kaempferol glycosides are mainly restricted in J. azoricum, L. On the other hand, quercetin-3-O-dirhamnoglucoside is present mainly in the 2 varieties of J.sambac, Ait. and absent in J. azoricum, L. Iridoids (Jasminin and azoricin), flavonol glycosides (rutin and quercetrin) and mannitol are present in all samples in a significant concentrations and can be considered as finger prints for them.
