Phytonutrient Composition of Two Phenotypes of Physalis alkekengi L. Fruit

Physalis alkekengi L. is the only representative of the genus Physalis (Solanaceae) that is native to Bulgaria, found in wild habitats under different climatic and soil conditions. The plant is poisonous, but produces edible fruit, which are a source of functional nutrients—vitamins, phenolic antiox...

Description
Summary:Physalis alkekengi L. is the only representative of the genus Physalis (Solanaceae) that is native to Bulgaria, found in wild habitats under different climatic and soil conditions. The plant is poisonous, but produces edible fruit, which are a source of functional nutrients—vitamins, phenolic antioxidants, minerals, etc. Therefore, the objective of this work was to determine the presence of certain nutrient and bioactive substances in two phenotypes of P. alkekengi fruit from Bulgaria, in order to better reveal the prospects of fruit use in nutrition. Different macro and micronutrients were determined in the fruit—protein, ash, lipids, fiber, natural pigments, sugars, amino acids, minerals—and the results showed differences between the phenotypes. Fruit energy values were low and identical in the samples, 43 kcal/100 g. The fruits were rich in extractable phenolics (TPC, 17.74–20.25 mg GAE/100 g FW; flavonoids, 15.84–18.03 mg QE/100 g FW) and demonstrated good antioxidant activity (DPPH, 171.55–221.26 mM TE/g; FRAP, 193.18–256.35 mM TE/g). P. alkekengi fruits were processed to obtain a dry extract with ethanol (yield 47.92–58.6%), and its individual composition was identified (GC-MS). The results in this study supported the presumed phytonutritive potential of P. alkekengi fruit, thus, opening doors for further research.
