BELTRAN CIFUENTES, Martha Cecilia et al. I STUDY FARMACOGNOSICO FOR THE CARE OF THE HEALTH FROM ESSENTIAL OILS OBTAINED BY DISTILLATION OF STEAM DRAGGING. Investig. andina [online]. 2010, vol.12, n.20, pp.8-18. ISSN 0124-8146.

Introduction: natural medicine has substantially addressed the ethnobotanical knowledge of medicinal plants from the study of active principles, using techniques of phytochemistry, for application in different fields of health, including cosmetology. The production of medicinal and aromatic plants is cost-effective when given added value to primary production, those are not as drugs marketed fresh or dried vegetables, but processed and transformed. In that sense can be obtained extracts, oils or develop phytomedicines, phytocosmetic, etc. Method: a study with an experimental approach which was taken as reference of the genus Ocimum species belonging to the family Labiatae (Lamiaceae) that are cultivated in the Department of Risaralda. The species studied were of the varieties: O. basilicum L. var cinammom, O. anisatum, O. purpurescens, O. album, O. thyrsiflorum, O. cf. gratissimum. Essential oils were obtainedfrom the aerial parts of each plant species by extraction of the steam distillation and solvent extraction with ethyl acetate. This procedure was performed in triplicate for each species and its chemical composition was determined by GC-MS. To identify the components of the oils used the database Wiley library (Seventh Edition Version 2003). The recording of data was performed using Microsoft Excel program. Results: the chemical composition of essential oils obtained by GC-MS, reported high in phenylpropane (eugenol, (E)-methyl cinnamate (Z)-methyl cinnamate) and oxygenated monoterpenes (eucalyptol, α-terpineol, β - terpineol and linalool). Conclusions: the results are confirmed by reviewing reports from other studies on the chemical composition of some varieties of basil grown in the department of Tolima. This study found a chemotype for them "methyl cinnamate", and volatiles of these plants were rich in phenylpropanoids.
