Abstract
Rosa × alba is cultivated almost exclusively for the production of aromatic water and fruits widely used as ingredients in some traditional food preparations sold commercially. Results of the proximate and elemental analyses revealed that flowers exhibited higher moisture content while the dry matter content was higher in leaves. Total fat and ash was higher in fruits when compared with leaves and flowers. All studied organs were found to be rich in essential mineral such as K, Ca, P and Mg. Qualitative and quantitative analysis of the volatile oils revealed different composition patterns between organs. Linalool and geraniol were found as major constituents of the leaf oil whereas 2-phenethyl alcohol and eugenol were the major constituents of the floral oil. In contrast, fruits showed very distinct composition and alkanes/alkenes were found to have the major contribution. The present composition could justify the traditional use of Rosa × alba which could be considered as a potential source of essential minerals and volatile constituents.
Highlights
The Rosaceae family is one of the most employed as a consolidated source of phytoproducts with functional properties[1]
The genus Rosa provides various species and their essential oils possess a wide range of applications as flavour, fragrance and additive in cosmetic and toiletries[2]
Any study concerned with the phytochemistry of this species is considered crucial to define the possible application areas for the rational use of this species. With regard to this topic, this study aims to provide the proximate, mineral and volatile oil composition of different organs of Rosa x alba which has not been reported to date
