This paper presents a phytochemical screening of extracts of M. sylvestris leaves and petioles. The antioxidant activity was studied in vitro by determination of DPPH, FRAP and phenolic compounds in the extracts. The soluble carbohydrates were also investigated. Results show that flower extracts have a higher amount of total phenolics with 6.32 ± 0.13 mg GAE/g FW, and total flavonoids with 1.45 ± 0.21mg QE/g FW. In general, more total soluble carbohydrates were found in the flowers 42.9 g/100 g FW, as reducing sugars presented mainly by glucose and fructose were also higher in the flowers – 5.5 g/100 g FW.
The results from current study evaluated mallow flowers as a rich source of bioactive compounds for healthy human nutrition.
