description |
The knowledge of the chemical composition of different plant organs provides valuable information for clarifying the functionality of secondary metabolites. Essential oils are secondary metabolites produced and stored in secretory structures on leaves, flowers, and steam. Many studies have shown that the chemical composition of the essential oil can differ depending on the plant organ and the secretory structures even if they are at the same organ. Such differences may be the consequence that organs also differ in type and density of glandular structure. Moreover, the same type of glandular structure can change its chemical composition depending on its position within the same organ. However, no study has been evaluating the chemical composition of the essential oil from the same glandular structure in leaves and fertile floral whorls. The aim of this work was to characterize the chemical composition of essential oils of peltate glandular trichomes from anthers and leaves of Lepechinia floribunda. We found a lower richness of chemical compounds and higher relative abundance of monoterpene hydrocarbons on anthers than leaves. Leaves showed an increased relative abundance of oxygenated sesquiterpenes. Such differences probably respond to a high tissue-specificity expression of genes in different plant organs. |

Composición química del aceite esencial de tricomas glandulares peltados en hojas y flores de Lepechinia floribunda (Lamiaceae). El conocimiento de la composición química del aceite esencial producido por distintos órganos en las plantas, brinda información para conocer las funciones de dichos compuestos. Los aceites esenciales son metabolitos secundarios producidos y almacenados en diferentes estructuras glandulares en hojas, flores y tallos. La composición química del aceite esencial difiere entre órgano de la planta y entre estructuras de secreción, incluso ubicadas en un mismo órgano. Tales diferencias podrían ser consecuencia del distinto tipo y densidad de estructuras glandulares en cada órgano. El aceite esencial del género Lepechinia ha sido escasamente estudiado, sin embargo su uso etnobotánico pone en evidencia propiedades medicinales y antisépticas. Hasta la fecha varios estudios han evaluado la composición química del aceite esencial en distintas partes de las plantas o de la misma estructura glandular en diferentes posiciones dentro de las mismas. Sin embargo, no se han encontrado estudios que evalúen la composición química del aceite esencial del mismo tipo de estructura glandular en hojas y verticilos florales fértiles. El objetivo de este trabajo fue caracterizar la composición química del aceite esencial proveniente de tricomas glandulares peltados de anteras y hojas de Lepechinia floribunda (Lamiaceae). Se encontró menor riqueza de compuestos químicos y un incremento en la abundancia relativa de monoterpenos hidrogenados en el aceite esencial de anteras que en hojas, mientras que en hojas hubo mayor abundancia de sesquiterpenos oxigenados. Estos cambios en la composición química probablemente respondan a la alta especificidad tisular en la expresión de genes que existe para cada órgano.
