Abstract
Objectives. Ocimum basilicum is one of the widespread medicinal plants, widely used due to its multiple therapeutic properties (antimicrobial, antiviral, hypoglycemic, antispasmodic, anti-inflammatory, carminative, stomachic, antioxidant, analgesic, etc.), as well as its specific aromatic character. The aim of this study was to comparatively investigate the chemical composition (flavonoids, caffeic acid derivatives, tannins, essential oil) of the aerial parts of some Romanian medicinal teas of Ocimum basilicum. Materials and methods. The content of flavonoids, phenolic acids and tannins in three samples of O. basilicum tea were determined spectrophotometrically. Identification of important phenolic compounds (rutin, isoquercitrin chlorogenic acid and caffeic acid) was performed by thin layer chromatography (TLC). The essential oils were obtained by hydrodistillation method. Outcomes and conclusions. Following the quantitative determinations performed, it can be seen that the basil samples are rich in active principles, and their use for the treatment of some diseases can be justified.

Summary
Ocimum basilicum L.(basil, Lamiaceae family) is an aromatic medicinal plant and is a rich source of bioactive principles [1,2,3,4,5]. Basil is a plant cultivated in many areas of Romania and is frequently used for medicinal purposes and to specific flavor. The aerial parts (Basilici herba) contain essential oil (with linalool, methyl chavicol, 1,8-cineole, eugenol, methyleugenol or methyl cinnamate), polyphenols (flavonoids, caffeic acid derivatives, etc.), triterpene acids, phytosterols, with antimicrobial, diuretic, antioxidant, digestive stimulant properties. The essential oil has antimicrobial, antifungal, insect-repelling, antioxidant activities [6,7,8]. The purpose of this research was the chemical analysis of some vegetal raw materials from three medicinal teas of O. basilicum from the Romanian market, in order to evaluate the quality of commercial products
