The genus Polianthes (Asparagaceae) is endemic from Mexico, the main use of this genus is ornamental, represented for this purpose tuberose (Polianthes tuberosa L.) which is mainly used in the perfumery for its sweet fragrance in its flowers. Regarding the wild species of this genus, little is known about the chemical composition in its different structures. In the present work, the volatile profile in flowers from wild and commercial cultivars belonging to the genus Polianthes was studied. Different compounds like aldehydes, alcohols, esters, monoterpenes, sesquiterpenes, and lactones were identified. The flowers of P. sessiliflora showed a similar composition with the commercial cultivars (P. tuberosa 'Simple' and 'Double'), while the rest of the wild genotypes showed different chemical composition. There are no studies analyzing the volatile compounds in flowers of wild specimens of the genus Polianthes, so this is the first study comparing the volatile composition in the flowers from wild and commercial cultivars, where the different profiles allowed us to group these genotypes for their use in perfumery, pharmaceutical or agro-industrial applications.
