As a part of a continuing chemotaxonomic survey of pigments in Crocus two new and three known anthocyanins have been isolated from the blue perianth segments of Crocus antalyensis [Mathew, B., The Crocus. B.T. Batsford, London]. The novel anthocyanins were identified as delphinidin 3- O-( β- d-glucopyranoside)-5- O-(6- O-malonyl- β- d-glucopyranoside and petudin 3,7-di- O-( β- d-glucopyranoside. Further 3,7-di- O- β- d-glucoside of delphinidin was isolated together with two minor components, 3,5-di- O- β- d-glucosides of delphinidin and petunidin. The complete structural determination of the compounds was achieved by use of 1D and 2D NMR techniques and other spectral evidence.
