In Local markets of Khyber Pakhtunkhwa, Pakistan dried medicinal flowers are available for different purposes. Local communities consume flowers for medicinal purposes. In order to confirm the authentication and standardization of these flowers are more important for consumption. For this purpose, the present study focused on the phytochemical, extractive values, nutritional, and elemental analysis of Althea officinalis, Hyssopus officinalis, Nymphaea alba and Sphaeranthus indicus flowers. The experimentation of elemental analysis (EA) through atomic absorption spectrophotometry, extractive values (EV) via percentage, and nutritional analysis (PA) by AOAC and phytochemical screening were carried out according to different protocols. Qualitative Phytochemical screening exhibited the existence of proteins, reducing sugars, saponins, hydrolyzable phytosterols, steroidal glycosides, phenols, triterpenoids, and terpenes, flavonoids, and fixed oils, while tannins were absent in all the flowers. The percent extractive value revealed that the highest extractive value was that of S. indicus (50.39±0.80%) in methanol. Elemental analysis of the flowers detected various nutrient elements (macro and micro) viz., sodium (7.421mg/L), magnesium (27.170 mg/L), potassium (12.840 mg/L), calcium (129.30 mg/L), iron (15.53 mg/L), copper (0.025 mg/L) zinc (0.543 mg/L), cobalt (0.035 mg/L), lead (0.725 mg/L), and cadmium (0.025 mg/L). The results of the nutritional analysis of the flowers revealed the presence of significant moisture contents (4.17±0.62%), ash contents (32.33±1.93%), proteins (14.11±0.81%), carbohydrates (34.25±0.94%), fats (6.70±0.42%), and fibers (22.00±1.22%). Gross energy was reported higher (308.25±5.06 Kcal/100g) by A. officinalis. Current study has revealed that all flowers have significant Phyto-constituents macro and micro elements within acceptable ranges, extractive values, and nutritional values that make the flowers suitable for medicinal consumption without toxic potential.
