ABSTRACT
Vitamin C (L-ascorbic acid) is as vital to flora as it is to animals. It is modulating the regeneration of antioxidants, hormone biosynthesis, and photosynthesis. This study includes the collection of Rosa brunonii rosehips from various locations in Murree Hills and the quantification of vitamin C in these samples. The average weight of rosehips varied from 4.54 to 7.92 g. Rosehips collected from Lower Topa (LT) showed the highest weight with a mean value of 7.92 g, followed by rosehips collected from Danoi (DA) (7.25 g). The average vitamin C content varied from 918 to 2985 mg/100 g. Whereas the total soluble solids (TSS), and total dry weight (TDW) varied from 31 to 34% and 34 to 40%, respectively. Rosehips collected from Bhurban (BH) showed the highest vitamin C content with 2985 mg/100 g along with 36% TSS and 40% TDW, followed by rosehips from Ghora Gali (GG) that had 2535 mg/100 g vitamin C content along with 35% TSS and 39% TDW. The difference in vitamin C content could be attributed to climate, including temperature and rainfall patterns, which directly influence plant growth and metabolism. Rosehips are used in the production of a variety of sweets and beverages, including syrup, marmalade, jellies, and jams. Therefore, high vitamin C content as well as TDW and TSS characteristics for rosehips are desired and preferable.
