Citrus essential oils are very complex matrices which contain numerous compounds of different chemical classes. These compounds are generally divided into two fractions: the volatile fraction, which is the most representative, and ranges between 85 and 99% in the different cold-pressed citrus oils, and the non-volatile residue, which ranges between 1 and 15%. The development of new instrumental...

A main target in the treatment of hypertension is the angiotensin-converting enzyme (ACE). This enzyme is responsible for producing angiotensin II, a potent vasoconstrictor. Therefore, one of the targets in the treatment of hypertension is to inhibit ACE activity. Hence, this study's aim is to use computational studies to demonstrate that the proposed heterocyclic compounds have a molecular aff...
