Phytochemical screening and assay of micro-constituents and macronutrients of oak cork fruits

Abstract

The medicinal plants play a great role in the treatment of a lot of different diseases. The use of remedies and the therapeutic qualities of plants are gaining renewed interest thanks to the improvement of extraction techniques and advances in structural analysis methods for the discovery of new active substances. The objective of our study was designed for the determination of micro constituents polyphenols (pericarps 10.13±0.46 GAE mg/g DM, almonds 9.12±0.26 GAE mg/g DM), and macronutrients sugars (almonds 1.84±0.08 mg/g DM), pericarps (0.494±0.02 mg/g DM), proteins (almonds 3.82±0.04 g/100g DM pericarps 1.74± 0.01 g/100g DM), present in oak cork fruits, and which play a very important role. We were interested in determining their content in dried, powdered oak cork fruits (acorns). The carried out phytochemical screening revealed the presence of flavonoids, tannins, and saponins, the presence of these compounds attribute to this species several therapeutic and pharmacological characteristics. The extraction of secondary and primary metabolites by the use of organic solvents gave significant portions that testify the richness of this species in active ingredients. This species (oak cork fruits) should be put in valor as well as complement or food and making the parapharmaceutical products.
