BARRIENTOS RAMIREZ, Lucía et al. Polyphenols content and antioxidant capability of wild and under cultivation Physalis chenopodifolia Lam. Rev. mex. de cienc. forestales [online]. 2019, vol.10, n.51, pp.182-200. ISSN 2007-1132.  https://doi.org/10.29298/rmcf.v10i51.323.

The composition of polyphenols as well as the antioxidant activity in Physalis chenopodifolia (Solanacea) has been little studied in Mexico. In this work the content of total phenols, total flavonoids and antioxidant activity was evaluated by two methods DPPH and ORAC, in leaves and fruits of wild plants and under culture of said species. The results showed that the leaves and fruits of the wild plants have more polyphenols content [196.46 and 9.44 mg 100 g-1 respectively of dry weight (PS)] and total flavonoids (148.52 and 23.1 mg 100 g-1 respectively of PS) than the cultivated plants. The antioxidant activity by the DPPH method revealed higher percentage in leaves of the cultivated plants (4.19-11.5 %) in all the concentrations, than those of wild plants (2.14-8.28 %). In fruits, the results were similar, both in the two types of plants; however, through the ORAC method, the leaves of wild plants had more activity than those of cultivated plants: of 1 396 and 156 μM Etx 100 g-1 of PS, respectively, data that correlated with the high values of total polyphenols (R2 = 0.953). Therefore, it is concluded that the contribution to the knowledge of the presence of polyphenols in different Solanaceae is important for the potential use of the species studied as an antioxidant.
