Physico-chemical and antioxidant properties of two medicinal wild plants grown in Moldova region

Sorina Ropciuc

Abstract


The major objective of this study is to report physico-chemical (moisture, ash, protein, total phenolic compounds and ascorbic acid) and the antioxidant properties of methanol extracts of nettle (Urtica dioica L.) and typical romaine spice "leurda" (Allium ursinum, wild garlic) fresh and dried. The antioxidant properties of methanol extract of medicinal herbs were evaluated using free radical scavenging test. The phenols were extracted from the medicinal plants with methanol solvent and were quantified by the Folin-Ciocalteu method. The ascorbic acid content varied between 77.94 mg/100g in the fresh Urtica dioica L. and 39.55 from fresh Allium ursinum. The results showed that the total phenolic compounds in all medicinal plants decreased along processing. These results suggest that the medicinal plants sample extract with highest polyphenolic content will indicates the possibility of using them  as ingredients in functional foods.


Keywords
