“…El aceite esencial de Lepechinia conferta (30), y Lepechinia shiedeana (31), de Venezuela exhibieron Ledol con 24,2 a 28,9% respectivamente como compuestos principales. Para el caso de Lepechinia floribuna de Argentina, Borneol 21,4%, β-Cariofileno 15,1% y acetato de ledilo 16,8% fueron los compuestos principales; sin embargo, para la misma especie recolectada en Bolivia, fue acetato de bornilo 12,3%, β-cariofileno 9,0% y canfeno 5,7% como compuestos principales (32).…”

“…En el aceite esencial de Lepechinia meyeni (Walp) Epling los monoterpenos constituían la fracción más importante con 61% seguidamente con 40% seguido de sesquiterpenos oxigenados (32). Otra especie endémica del género Lepechinia presente en Chile (35), reportó una composición particularmente rica en sesquiterpenos (50.6%), pero con porcentajes similares de componentes oxigenados e hidrocarburos (26,4%) y (24,2%) respectivamente.…”

Las hierbas aromáticas tienen una amplia distribución en la región de Apurímac, Perú, donde encontramos especies silvestres y cultivadas, su interés se basa en la presencia de aceites esenciales que contiene componentes bioactivos que son usados como conservantes en la industria de alimentos. El objetivo de la investigación fue determinar el perfil químico y actividad antioxidante de los aceites esenciales de Lepechinia meyenii (Walp) Epling y Mentha piperita L. La extracción de aceites esenciales se realizó mediante la destilación por arrastre de vapor de agua a condiciones de sobresaturación. Se determinaron los siguientes parámetros: rendimiento de extracción, densidad relativa e índice de refracción. El perfil químico se realizó mediante la cromatografía de gases acoplada a espectrómetria de masas y la actividad antioxidante mediante la eliminación del radical libre 1,1-difenil-2-picrilhidrazilo y H2O2. (DPPH), como resultado, el porcentaje de rendimiento fue del 0,87 % y 0,56 %, con densidades de 0,942 g/mL y 0,919 g/mL y índice de refracción de 1,4917 y 1,4676 para Lepechinia meyenii (Walp) Epling y Mentha piperita L.), respectivamente. Los aceites esenciales se caracterizaron principalmente por una fracción sesquiterpenoides en un (55,73 %) y con una fracción monoterpenoides en un (55,60 %). La actividad antioxidante fue significante de 4,95-0,06 mg/mL y 7,21-0,21 mg/ mL. Los aceites esenciales a partir de hierbas aromáticas presentaron significativamente altos componentes químicos y actividad antioxidante, siendo posibles candidatos antimicrobianos, antioxidantes, antibacterianas para la industria alimentaria.

In order to investigate the influence of drying, the essential oil from fresh, shade dried and sun dried flowering twigs of Artemisia capillaris was compared. The essential oil content was found higher in fresh herb (0.63 %) compared to dry materials (0.57 %). GC and GC-MS analysis enabled identification of twenty five components, representing 93.8 % -95.0 % of the total oil. The major components of these oils were capillene (32.5 % -39.6 %), γ-terpinene (26.4 % -34.3 %), eugenol (7.4 % -10.1 %), β-caryophyllene (4.8 % -7.9 %) and ρ-cymene (2.0 % -5.1 %). Interestingly, capillene content was found to decrease, whereas γ-terpinene and eugenol increased on drying. The study suggested that the A. capillaris biomass should be distilled afresh for better oil yield and quality under hill conditions of Kumaon Himalaya.

“…The Literature survey based on geranylacetone natural products and relative compounds, reveals that 9-geranylnyl-p-cymene is a rare diterpene originally observed in Helichrysum species, also members of the Asteraceae family (Figure 1) [7,8]. 9-(15,16-Dihydro-15-methylene)-geranyl-p-cymene and 9-(15,16-dihydro-15-methylene) -geranyl-α-terpinene were first identified in the essential oils of the flowers of Tanacetum annuum (Asteraceae) [9,10]. Larvicidal activity of Eucalyptus globulus leaf essential oil was effective against 4th instar larvae of C. quinquefasciatus compared to Temephos [11].…”

Larvicidal Activity of Geranylacetone Derivatives against Culex quinquefasciatus Larvae and Investigation of Environmental Toxicity and Non-Target Aquatic Species

A grindstone method based on Mannich condensation was used to synthesize geranylacetone derivatives (1a–1f). The method showed a high yield under milder reaction conditions. Analyses of the synthesized compounds were carried out by FTIR, 1H, 13C NMR, mass spectrometry, and elemental analysis. We synthesized and evaluated the larvicidal and ichthyotoxic activities of six compounds (1a–1f) in this study. Compound 1f (5,9-dimethyl-1-phenyl-3-(2-(3-phenylallylidene)hydrazinyl)deca-4,8-dien-1-one) was more active (LD50: 14.1 µg/mL) against the second instar larvae of Culex quinquefasciatus than geranylacetone (67.2 µg/mL), whereas the former caused 13.9% mortality at 100 µg/mL. Geranylacetone, in an antifeedant screening test, showed 53.1% against Oreochromis mossambicus within 24 h. The compound 1f showed high larvicidal activity against C. quinquefasciatus and was non-toxic to non-target aquatic species.
