La web ‘Etnobotànica dels Països Catalans’: coneixement tradicional al servei de la societat

Presentamos en este trabajo la web ‘Etnobotánica de los Países Catalanes’ (https://etnobotanica.iec.cat), una herramienta interactiva para redescubrir el saber popular sobre las plantas. En el momento de hacerse pública, contiene casi 80.000 entradas con nombres de plantas y 55.000 con usos medicinales, y se trabaja para introducir, en los próximos dos años, unas 30.000 entradas de usos alimentarios y unas 30.000 más de otros usos y otras informaciones. Estos datos provienen de más de 1300 entrevistas realizadas a casi 2000 informantes de alrededor de 500 municipios del dominio lingüístico catalán. Los territorios de lengua catalana se encuentran entre las áreas del sur de Europa mejor prospectadas etnobotánicamente, y actualmente sigue habiendo investigaciones activas. La información hasta ahora volcada ha originado un centenar de obras, cuya lista se puede consultar en la misma web. En cuanto a nombres populares, los táxones con mayor diversidad son Zea mays, Achillea millefolium, Cynara cardunculus, Hypericum perforatum y Ceterach officinarum. En cuanto a usos medicinales -los únicos que por el momento figuran-, los táxones más reportados son Thymus vulgaris, Sambucus nigra, Olea europaea subsp. europaea var. europaea, Matricaria recutita y Rosmarinus officinalis. Esta página web es una buena herramienta para el retorno a la sociedad de un saber sobre los patrimonios natural y cultural que de ella proviene, conservándolo y poniéndolo al alcance de las nuevas generaciones y, además, permitirá detectar huecos en la investigación etnoflorística, realizar metanálisis hasta ahora muy raramente hechos en etnobotánica y suministrar información a instituciones y empresas interesadas en desarrollar productos comerciales a base de plantas.

Olea Europaéa

Background: The present study investigated the antifungal activity and mode of action of four Olea europaea leaf extracts, Thymus vulgaris essential oil (EO), and Boswellia carteri EO against Fusarium oxysporum. Methods:Fusarium oxysporum Lactucae was detected with the internal transcribed spacer (ITS) region. The chemical compositions of chloroform and dichloromethane extracts of O. europaea leaves and T. vulgaris EO were analyzed using GC-MS analysis. In addition, a molecular docking analysis was used to identify the expected ligands of these extracts against eleven F. oxysporum proteins. Results: The nucleotide sequence of the F. oxysporum Lactucae isolate was deposited in GenBank with Accession No. MT249304.1. The T. vulgaris EO, chloroform, dichloromethane and ethanol efficiently inhibited the growth at concentrations of 75.5 and 37.75 mg/mL, whereas ethyl acetate, and B. carteri EO did not exhibit antifungal activity. The GC-MS analysis revealed that the major and most vital compounds of the T. vulgaris EO, chloroform, and dichloromethane were thymol, carvacrol, tetratriacontane, and palmitic acid. Moreover, molecular modeling revealed the activity of these compounds against F. oxysporum. Conclusions: Chloroform, dichloromethane and ethanol, olive leaf extract, and T. vulgaris EO showed a strong effect against F. oxysporum. Consequently, this represents an appropriate natural source of biological compounds for use in healthcare. In addition, homology modeling and docking analysis are the best analyses for clarifying the mechanisms of antifungal activity.

Olea Europaéa

Phenolic compounds are secondary metabolites that are found ubiquitously in plants, fruits, and vegetables. Many studies have shown that regular consumption of these compounds could have a positive effect on our health. The aim of this study was to compare the phytochemical contents of the water extracts from three different plants used as folk remedies in Turkey: Aesculus hippocastanum, Olea europaea, and Hypericum perforatum. A liquid chromatography-electrospray tandem mass spectrometry (LC-ESI-MS/MS) analysis was performed to explore the phenolic profiles. The biological activities of these extracts were also evaluated in terms of their antioxidant activities (2,2-diphenyl-1-picrylhydrazyl DPPH, 2,2′-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid ABTS, Ferric Reducing Antioxidant Power Assay FRAP, cupric ion reducing antioxidant capacity CUPRAC, β-carotene, phosphomolybdenum, and metal chelating) and enzyme inhibitory properties (against acetylcholinesterase, butyrylcholinesterase, and tyrosinase). The aqueous extract of H. perforatum showed the highest levels of total phenolic, flavonoid, and saponin contents. Protocatechuic acid, vanillic acid, verbascoside, hesperidin, hyperoside, apigenin 7-hexosides, and quercetin were the most common compounds found in this species. The results confirm that A. hippocastanum, O. europaea, and H. perforatum represent a potential source of natural-derived molecules with positive properties that could be used as valid starting point for new food supplements, and drugs in the pharmaceutical, cosmetic, and food industries.

During the last years, the addition of essential oils to livestock rations became increasingly popular. Numerous studies have proved the antibacterial properties of herbal essential oils (ЕО) along with antioxidant, anticarcinogenic and digestive properties. They are also used as growth promoters of livestock. With this regard, the purpose of the present study was to investigate the effect from addition of 0.01% essential oils (EO) from Matricaria chamomilla; Rosmarinus officinalis; Lavandula angustifolia; Origanum vulgare; Thymus vulgaris; Hypericum perforatum to the feed of turkey broilers on live body weight, feed consumption, slaughter traits, fatty acid content and meat quality. Female turkey broilers, were divided into 7 groups of 15 birds in each after being weighed and labelled (each group comprised 3 subgroups of 5 birds). Groups were one control (С) and six experimental (Т1, Т2, Т3, Т4, Т5, Т6). The control (С) group of turkeys received feed according to the requirements of their age without herbal essential oils. The experimental groups received the same diet supplemented as followed: group Т1- 0.01% EO from Matricaria chamomilla; Т2- 0.01% EO from Rosmarinus officinalis; Т3- 0.01% EO from Lavandula angustifolia; Т4-0.01% EO from Origanum vulgare; Т5- 0.01% EO from Thymus vulgaris; Т6- 0.01% EO from Hypericum perforatum). The addition of 0.01% ЕО of abovementioned herbs influences breast and thigh meat pH measured at 24th post mortem hour (pH24) (Р<0.05). The highest value L* in breast meat was demonstrated in birds supplemented with EO from Lavandula angustifolia (T3) and lowest L* in group T5 at (Р<0.05). The highest value L* in thigh meat was measured in birds from group Т2 (ЕО from Rosmarinus officinalis) and the lowest- in group Т5 (ЕО from Thymus vulgaris). The redness (a*) and yellowness (b*) of breast meat did not differ significantly among the groups (Р>0.05), yet a* and b* values showed considerable differences in thigh meat (Р<0.05). The dietary EO also had an effect on thigh meat L*, a* and b* - parameters of meat colour. Cooking loss % of breast meat was the highest in the control group- 35.12% and the lowest in group Т5 (Thymus vulgaris EO) - 23.69% and group Т6 (Hypericum perforatum EO) - 24.78% (Р<0.001). The addition of herbal ЕО to the ration of turkey broilers did not influence the content of saturated and unsaturated fatty acids (linoleic acid, ά-linolenic acid, arachidonic acid, eicosapentaenoic acid and docosahexaenoic acid) of breast and thigh meat of birds from experimental groups.
