IMPORTANCIA DEL ACEITE ESENCIAL Y LA PRODUCCION DE ORÉGANO Lippia palmeri Watson EN EL ESTADO DE SONORA

Abstract

El saber de mis hijos hará mi grandeza" 57Volumen XV, Número 1 RESUMENEl orégano, es una planta aromática de climas áridos y semiáridos de Sonora. En este estudio se analiza el contenido del aceite esencial y algunas características fisicoquímicas, de material recolectado de dos localidades silvestres [Puerto del Orégano (AEPO) y Álamos (AEA)] y uno cultivado (AEOC). Se evaluaron algunas prácticas agronómicas, se observó el comportamiento de la planta en estado silvestre, y se evaluó la germinación en respuesta a cinco dosis de ácido giberélico (AG 3 ) 0, 100, 200, 300, 400 y 500 ppm en tres tiempos de remojo. En la evaluación de la propagación asexual, las estacas se sometieron a 0, 2000, 3000, 4000 y 5000 ppm de ácido indol-3butirico. Los compuestos más abundantes estuvieron en la localidad de AEPO siendo principalmente carvacrol (24.57%), timol (15.11%) y p-cimeno (14.25%). Para la localidad de AEA los compuestos más abundantes fueron: p-cimeno (22.37%), timol (21.39%) y carvacrol (8.76%). En AEOC, el timol (28.90%), p-cimeno (24%) y carvacrol (12.80%) fueron los más abundantes. Los tres aceites esenciales difieren en las concentraciones de sus componentes, lo cual pudiera deberse a las condiciones ambientales. En germinación, 100 ppm de AG 3 durante 60 minutos se obtuvo el 90%; las dosis de 3000 y 4000 ppm de ácido Indol-3butírico, mostraron el 75% de enraizamiento. Con densidades de 5000 plantas ha -1 , se producen 2,240 kg de hoja seca.

Antiproliferative Effect of Essential Oil Obtained from Oregano (Lippia palmeri S. Watson) Leaves Grown in Hydroponics and LED Light

“…Like other species of the genus Lippia , L. palmeri shows high variability in the composition of its essential oil. Chemotypes for this species have been described, including carvacrol, thymol, and p‐ cymene [5] . There is an evident chemical polymorphism of EOs within the species under a different light treatment, as shown by the variability in the composition of L. palmeri in our study and the literature cited ( Table 3).…”

Bueno et al, [35] mentioned that EO from Lippia spp.…”

“…Found percentage of carvacrol and thymol in this work was higher than in other reports in wild samples of L. palmeri from two locations of the same region, where the sum of these compounds was 30.15 and 39.68 %. [5] Plants have numerous mechanisms to adapt to environmental changes by producing a repertoire of secondary metabolites, which generate a variety of responses to changes in the environment. These changes can be induced by environmental components, including seasonal or climatic changes, temperature, light, humidity, and developmental processes, impacting biomass production and biosynthesis of secondary metabolites.…”

COMPOUNDS WITH in vitro ANTIBACTERIAL ACTIVITY FROM HYDROSOL OF Lippia palmerI AND MORPHOMETRIC CHANGES ON Listeria monocytogenes

“…Leaves of L. palmeri plant were collected in the region of Alamos, Sonora, Mexico at 380 meters above sea level, at 27°01' N and 108° 56' W, during the spring. They were transported to the laboratory and dried in the dark at 15 °C for 3 weeks (Corella-Bernal and Ortega-Nieblas, 2013). Hydrosols were obtained by hydrodistillation employing 100 g of dry plant in 500 mL of distilled water, and the extraction was conducted for 3 h in a Clevenger hydrodistilator (AOAC, 1990).…”

Correlation between Relative Humidity and Forest Seeds Moisture on the Incidence of Fungi

“…In addition to the importance of A. lechuguilla, L. graveolens, and N. cespitifera, some endangered species have priority within the phytogenetic resources for their in vitro conservation, and Agave is one of them as well as Allium L. e importance of seeds under study is big; for instance, A. lechuguilla is used for the production of aguamiel and pulque, as distilled alcoholic beverages such as tequila and mezcal, and also to obtain fibers, food, and materials for ornaments and construction, among others [83]; N. cespitifera is for a large number of families in rural areas of arid and semiarid zones of northeastern Mexico [84]. It is the main source of economic income, obtaining a high resistance hard fiber used as raw material in the manufacture of brooms, brushes, rustic furniture, and explosive cartridges [85], and L. graveolens have industrial and pharmaceutical uses; its essential oil is used as a fragrance in soaps, perfumes, cosmetics, and flavorings, [86]; in addition, it is used as a condiment in the preparation of regional dishes such as sauces, stews, broths, and salads and in international foods as pizzas and the production of sausages [87].…”
