FUNG BOIX, Yilan et al. Qualitative evaluation of monoterpenes in Rosmarinus officinalis cultivated with magnetically treatment water. cultrop [online]. 2016, vol.37, suppl.1, pp. 136-141. ISSN 1819-4087.

Lamiaceae (labiatae labiadas) family have many species for example Rosmarinus officinalis L., it is one of the species with the highest antioxidant power by the presence of essential oils, monoterpenes and phenolic compounds. Its vegetative propagation in Cuba is one of its difficulties and in recent years, this species has been removed from the National Formulary of Phytopharmaceuticals because of its availability. The magnetically treated water has been used for irrigation because it stimulates the growth and development of plants, showing that its application can activate metabolism of cells; however, studies have been very limited in these respects. The aim of this work was to evaluate monoterpen bioactive compounds present in the species Rosmarinus officinalis L., cultivated with magnetically treated water in Santiago de Cuba. N-hexane extracts were analysed by the method of thin layer chromatography of high-resolution (HPTLC) silica gel (fluka plates, foils analytical Alu thickness 0, 2 mm) with a solvent system of toluene and ethyl acetate. Monoterpen standard solutions as cineol, borneol, geraniol, linalool, citral, eucalyptol, citronellal were used and two types of developers vanillin in 10 % ethanol and a solution of sulphuric acid in ethanol, the observation was with white light. The results showed that hexane extracts from treated plants with 120 mT and control plants had the presence of monoterpens, and it was identified with retention factor (R_f) between 0,08 to 0,93
