Stara Planina Mt is rich in medicinal plants, that are natural sources of various bioactive substances and have many useful medicinal properties. Rosehip, the fruit of wild rose (Rosa canina L.) is very popular and widely used. There is extensive empirical evidence of its therapeutic effects. The high content of vitamins, organic acids, phenolic compounds, carotenoids and pleasant taste define it as a valuable dietary supplement.

There are different procedures for making rosehip teas. In this paper, we have optimized the process of preparation of rosehip tea from the aspect of maximum extraction and preservation of vitamin C content in tea. The antioxidant activity of aqueous extracts of rosehips, depending on the extraction time and the temperature at which the extraction is performed, was also examined..The free radical scavenging activity of the plant extracts was analyzed by using the 2.2-diphenyl-1-picrylhydrazyl (DPPH) assay.

Optimal conditions are 30 minutes and a temperature of 40 °S. In this way, vitamin C is best extracted and its stability is preserved, which results in the high antioxidant activity of the tested teas.
