Comparative Study On Total Polyphenols Content Of Tunisian Wild Rhus Pentaphylla Fruit Extracts And The Evaluation Of Their Biological Activities

This study was focused on determining the total polyphenols content and biological activities from wild Rhus pentaphylla fruits at two different maturity stages, (stage 1: green-yellow fruits and stage 2: purple-red fruits Highly significant (p <= 0.01) increase was observed in total phenolic contents of fruits ranging from 158.65 +/- 0.06 to 177.57 +/- 0.06 mg Eq.AG.100 mg DW. In contrast, both total flavonoid (from 157.34 +/- 0.07 to 152.69 +/- 0.14 mg Eq.Cat.100 mg DW) and condensed tannins contents (from 200.26 +/- 0.30 to 131.23 +/- 0.24 mg Eq.Cat.100 mg DW) showed dramatic decreases (p <= 0.01). Evaluation of biological activities has provided good effects. Our results show the importance of using this wild fruits in pharmaceutical industries.
