Preliminary Phytochemical Screening of Five Commercial Essential Oils

摘要

The discovery of natural resources from plants remains crucial for the development of new therapeutic remedies. The present study focused on the phytochemical study of commercial essential oils of certain medicinal plants: Thym (iThymus vulgaris/i), basil (iOcimum basilicum/i), sage (iSalvia officinalis/i), Garden cress (iLepidium sativum/i) and lettuce (iLactuca sativa/i). The qualitative dosage of twelve secondary metabolites showed the presence of terpenoids and saponins in all tested oils while steroids, alkaloids, anthraquinones and phlobatannins were absent. The results obtained are encouraging and the secondary metabolites present in these oils were responsible for certain activities, hence the interest of their uses in traditional phytotherapy as well as the pharmacological and cosmetic field.
