Comparative Phytochemical Analysis and Mineral Profile of Rosa damascene and Rosa centifolia
Main Article Content
Abstract
The present study was mainly focused to analyse the phytochemical, biochemical quantification and mineral profile of dried rose petals of Rosa damascena and Rosa centifolia. The Quantitative analysis of carbohydrates, protein, phenol and the qualitative phytochemical analysis were carried out in aqueous and ethanolic extract of Rosa damascena and Rosa centifolia petals using the standard procedures. From the present study it can be interpreted that the preliminary phytochemical analysis of the aqueous and ethanolic petal extract of Rosa damascena showed positive results in many tests namely carbohydrate, protein, flavonoid, glycosides and alkaloids. Nutrient composition of the dried rose petals of R. damascene and R. centifolia contain carbohydrate, protein and phenol. The highest amount of carbohydrate (448.70 mg GL /gm), Protein (312.33mg BSA/gm) and phenol (287.42 mg GAE/gm) were observed in Rosa damascene and the lowest amount of carbohydrate (100.22 mg GL /gm), Protein (170.17mg BSA /gm), and phenol (245.45mg GAE/gm) were observed in Rosa centifolia. Mineral profile of the following parameters such as Nitrogen, Potassium, Calcium, Magnesium, Chloride, Iron, Sodium, Sulphate were determined and quantified. In conclusion, the presence of nutrients was considered to be the first biochemical quantification that reports the major nutrients of carbohydrates, proteins and phenol and some minerals in the dried rose petals of Rosa damascene and Rosa centifolia that can be strongly recommended for human diet intake.
