“…Delimitation of taxa is one of the main objectives of systematic classification. Chemical components can be used as markers to assess taxonomical correlation of plant species . The study of FAs composition of the seed oils can be used as one of the appropriate tools for appraising relationships between the plant taxa .…”

In this study, the seed oil content and fatty acid (FA) profile of 21 populations from 16 wild Salvia species of Iran were analyzed by GC. Patterns of chemical variations of the oils among species were identified via numerical analyses and also the taxonomic status of the infrageneric grouping was outlined in the genus. Salvia species were scored based on the contents of main FAs using principal coordinate analysis (PCO). The results showed that the total oil content in the seeds varied significantly, and ranged from 6.68 to 38.53% dry weight. α-Linolenic (18:3ω3, 1.69 - 53.56%), linoleic (18:2ω6, 13.04 - 60.64%), oleic (18:1ω9, 6.15 - 27.06%), palmitic (16:0, 3.77 - 9.27%), and stearic (18:0, 1.78 - 3.05%) acid were identified as five major FAs in the oils. The amount of ω-3 and ω-6 FAs ranged between 1.90 - 53.80% and 13.46 - 60.83% of total FAs in the seed oils, respectively. The results confirmed that FA profiles were distinctive among the species and that they can be used as chemotaxonomic markers. The discrimination of Salvia species according to their botanical classification at intersectional level was supported. In general, seed oils of Salvia species were rich sources of polyunsaturated FAs, except in linoleic and α-linolenic acid, and may be valuable for food and pharmaceutical industries.

“…In this context, we performed an antiviral screening of three plants endemic to Turkey flora and here we report on the anti-HRoV activity of Rindera lanata (Boraginaceae). Boraginaceae is a plant family represented by about 2,000 species in the world [15]. The genus Rindera includes about 25 species distributed mainly in Central and Western Asia [16], four of which growing in Turkey, namely R. lanata , R. caespiota , R. albida and R. dumani.…”

BackgroundHuman rotavirus (HRoV) is the leading cause of severe gastroenteritis in infants and children under the age of five years. No specific antiviral drug is available for HRoV infections and the treatment of viral diarrhea is mainly based on rehydration and zinc treatment. In this study, we explored medicinal plants endemic to Turkey flora as a source of anti-HRoV compunds.MethodsWe performed an antiviral screening on Ballota macrodonta, Salvia cryptantha and Rindera lanata extracts by focus reduction assay. The extract with the highest selectivity index (SI) was selected; its antiviral activity was further confirmed against other HRoV strains and by virus yield reduction assay. The step of viral replicative cycle putatively inhibited was investigated by in vitro assays.ResultsThe methanolic extract of R. lanata (Boraginaceae) showed the most favourable selectivity index. This extract exhibited a dose-dependent inhibitory activity against three different HRoV strains (EC50 values ranging from 5.8 μg/ml to 25.5 μg/ml), but was inactive or barely active against other RNA viruses, namely human rhinovirus and respiratory syncytial virus. The R. lanata extract targets the early steps of HRoV infection, likely by hampering virus penetration into the cells.ConclusionThese results make the R. lanata methanolic extract a promising starting material for a bioguided-fractionation aimed at identifying anti-HRoV compounds. Further work is required to isolate the active principle and assess its clinical potential.

“…In addition, Echium oil fatty acids contained predominantly α-linolenic acid (31.7%), oleic acid (14.5%), linoleic acid (14.1%), stearidonic acid (13.7%) and γ-linolenic acid (10.7%). The fatty acid profile of Echium oil fatty acids was found to be close to the Echium oil fatty acid composition (Guil-Guerrero et al, 2000;Özcan, 2008;Bilgiç and Yeşilçubuk, 2012).…”

SUMMARY:Structured lipids (SLs) were produced from the free fatty acids of Echium oil and tricaprylin by enzymatic acidolysis reactions. Lipozyme ® RM IM, immobilized sn-1,3 specific lipase was used in the enzymatic reactions. In order to optimize the incorporation of stearidonic acid (SDA), three factors were chosen , reaction time (6-12 hour) and substrate molar ratio (3-6 mol/mol (total free fatty acids/ tricaprylin)] for the application of response surface methodology (RSM) using a central composite circumscribed design (CCC) with five levels. The optimum temperature, time and substrate molar ratio obtained from the models were 60 ºC; 6 h, 6 mol/mol, respectively. Furthermore, SLs with 6.2% SDA content at sn-2 position were produced by scaling up the process. SL was obtained with nearly 78-79% of long-chain fatty acids at the sn-2 position. According to the melting profile analysis, the melting peaks of tricaprylin and Echium oil were sharper and narrower while the SL had more broadened peaks. KEYWORDS: Echium oil; Enzymatic acidolysis; Lipozyme® RM IM; Response surface methodology; Stearidonic acid; Tricaprylin RESUMEN: Uso de ácidos grasos de aceite de Echium y tricaprilina como sustratos de interesterificación enzimática para la producción de lípidos estructurados. Se produjeron lípidos estructurados (SL) a partir de ácidos grasos libres de aceite de Echium y tricaprilina mediante reacciones de acidolisis enzimática. Se usó Lipozyme ® RM IM, lipasa inmovilizada específica de sn-1,3 en las reacciones enzimáticas. Para optimizar la incorporación de ácido estearidónico (SDA), se eligieron tres factores [Temperatura de reacción (50-60 ºC), tiempo de reacción (6-12 horas) y proporción molar del sustrato (3-6 mol/mol (total de ácidos grasos libres) / tricaprylin)] para la aplicación de la metodología de superficie de respuesta (RSM) mediante el uso de un diseño compuesto central circunscrito (CCC) con cinco niveles. La relación óptima de temperatura, tiempo y sustrato obtenida de los modelos fue 60 ºC; 6 h, 6 mol/mol. Además, se produjeron SL con un contenido de SDA del 6,2% en la posición sn-2 mediante el proceso de escalamiento, SL se obtuvo con casi 78-79% de ácidos grasos de cadena larga en la posición sn-2. Según el análisis del perfil de fusión, los picos de fusión de la tricaprilina y el aceite de Echium fueron más agudos y estrechos, mientras que los SL tuvieron picos más amplios.
