dc.description.abstractThe plants offer since time immemorial products with beneficial properties useful in health, food, construction and decoration among others. In the Andean region among ornamental plants, a species known as “false incense” was selected due to its aroma, which was striking to start a chemical study and its ethnobotanical applications; For this purpose it was necessary to carry out a literature review on the Plectranthus genus which includes taxonomic classification, geographical distribution, morphology and its chemical composition. According to this, genus under study have diterpenic compounds such as abietane, pimaranes and clerodanes. In addition, for many species, the results show the presence of essential oils (EOs), for which the preliminary chemical characterization of the essential oil of the introduced species determined as Plectranthus madagascariensis Pers (Benth), belonging to the Lamiaceae family, was determined. The extraction of the EO was made by steam distillation. A sample was analysed by Gas Chromatography with mass detector (GC-MS). 78 constituents were detected in this study: monoterpenic hydrocarbons (0.4%), oxygenated monoterpenes (0.9%), sesquiterpenic hydrocarbons (78.5%), oxygenated sesqui-terpenes (13.8%) diterpenic hydrocarbons (0,5%) and unidentified compounds (6%). The major constituents were ß-gurjunene (24%), α-santalene (11%), valencene (7.7%) and Spatulenol (4%). This is the first EO study of P. madagascariensis conducted in Colombia whose results offer the possibility of developing phytotherapeutic products, for aromatherapy and cosmetology.spa
dc.description.abstractLas plantas ofrecen desde tiempo inmemorial productos con propiedades benéficas útiles en salud, alimentación, construcción y decoración entre otras. En la región andina entre las plantas ornamentales destaca una especie conocida como “falso incienso” por su aroma lo cual fue llamativo para iniciar un estudio químico y de sus aplicaciones etnobotánicas; a tal efecto fue necesario realizar una revisión bibliográfica sobre el género Plectranthus el cual incluye la clasificación taxonómica, la distribución geográfica, la morfología y su composición química. De acuerdo a esto en el género bajo estudio son comunes compuestos diterpenicos tipo abietano, pimaranos y clerodanos entre otros; además para numerosas especies los resultados muestran la presencia de aceites esenciales por lo cual se realizo la caracterización química preliminar del aceite esencial (AE) de la especie introducida determinada como Plectranthus madagascariensis Pers (Benth), perteneciente a la familia Lamiaceae. La extracción del AE se realizó por destilación arrastre con vapor. Una muestra se analizó por Cromatografía de Gases con detector de masas (CG-EM). Se detectaron en este estudio 78 constituyentes así: hidrocarburos monoterpenicos (0,4%), monoterpenos oxigenados (0,9%), hidrocarburos sesquiterpenicos (78,5%), sesqui-terpenos oxigenados (13,8%) hidrocarburos diterpenicos (0,5%) y compuestos no identificados (6%). Los constituyentes mayoritarios fueron el ß-gurjuneno (24%), α-santaleno (11%), valenceno (7,7%) y espatulenol (4%). Este es el primer estudio del AE de P. madagascariensis realizado en Colombia cuyos resultados ofrecen la posibilidad de desarrollo de productos fitoterapéuticos, aromaterapia y cosmetología.spa
