Santuarios y fortalezas: cuestiones de indigenismo, helenización y romanización en torno a Emporion y Rhode (S VI-I a.C.)

Se presentan diversas cuestiones de la relación entre los modelos helénicos de las colonias de Emporion y Rhode y las costumbres indígenas evidenciadas en los yacimientos ibéricos de su entorno. Los cultos de Artemis y Apolo como dioses protectores de la emporía arcaica de los foceos, el urbanismo de Rhode en el siglo III a.C., los cultos emporitanos, la interpretación del yacimiento de Pontós, la mezcla de cultos griegos y celtas en Ullastret y Pontós y un cálato excepcional en un campo de silos al pie de S. Julià, se estudian como evidencias de esta relación. En el siglo II a.C., Roma implantará un nuevo orden político y económico del que Emporion será la gran beneficiada.

Léxico patrimonial y metacedeusis en los nombres de lugar

En este artículo vamos a ocuparnos de uno de los mecanismos de transformación del patrimonio lingüístico: la metacedeusis. Es un procedimiento que contribuye a la renovación del repertorio léxico y, en especial, del toponímico. Intentamos en primer lugar mostrar que no coincide con lo que se ha venido llamando etimología popular. En segundo lugar enumeramos y ejemplificamos algunos de los factores que favorecen la aparición de este fenómeno. A lo largo de toda la exposición, nos esforzamos en demostrar que solo el conocimiento del léxico patrimonial permite detectar los casos de metacedeusis y, en consecuencia, trazar adecuadamente la historia del topónimo.

Myyttinen nainen johtajana – diskurssianalyysi ”naisjohtajan” kuvan rakentumisesta mediatekstissä

Tutkielman tavoitteena on selvittää, minkälaisista näkökulmista naisesta johtajana kirjoitetaan ja löytyykö mediateksteistä viittauksia myytteihin, arkkityyppeihin tai stereotypioihin. Tutkimusmenetelmänä käytetään diskurssianalyysiä, jonka avulla valittuja tekstejä tutkitaan. Tässä tutkimuksessa media on rajattu käsittämään sanoma- ja aikakauslehdet. Media muokkaa, mallintaa ja uusintaa lukijan käsityksiä naisesta johtajana. Mediatekstissä johtajuus määrittyy miehisen maailmankuvan kautta. Roolijako miehen ja naisen välillä on kirjoituksissa selvä. Naiseen johtajana liitetään sukupuoli, perhe ja yksityiselämä, mies mielletään kirjoituksissa pelkästään johtajaksi. Perheen merkitys naisen johtajakuvassa on hyvin voimakas. Asenteiden ja uskomusten muutostarpeet ovat olemassa, mutta muutokset tapahtuvat hyvin hitaasti. Media ylläpitää ja uusintaa vanhoja arvoja ja asenteita. Myytit, arkkityypit ja stereotypiat vaikuttavat alitajuisesti sosiaalisen todellisuuden rakentumiseen. Ne säilyvät ja vaikuttavat kansantaruissa, mytologioissa ja uskomuksissa, kuten myös mediatekstissä. Medialla voidaan katsoa olevan merkitystä ”naisjohtajan” kuvan rakentumiseen.

Constituintes químicos de Gustavia augusta L. (Lecythidaceae)

Gustavia augusta is used in the folk medicine against leishmaniosis and showed anti-inflammatory action. The phytochemical studies of the plant stem bark have led to the isolation of (22E)-stigmasta-7,22-dien-3beta-ol, 24alpha(S)-ethyl-5alpha-colesta-7,trans-22-dien-3-one, D-friedoolean-14-en-3beta-ol, D-friedoolean-14-en-3-one and D-friedoolean-14-en-3alpha-ol along with stigmasterol, alpha-amyrin, beta-amyrin, lupeol, 3alpha-hidroxi-lupeol and betulinic acid. The structures of these compounds were identified by IR, GC/MS, ¹H and 13C NMR spectral analysis and comparison with literature data.

Plantas do gênero Bauhinia: composição química e potencial farmacológico

Plants of the genus Bauhinia (Leguminosae) are widely distributed in most tropical countries and have been frequently used in folk medicine to treat several ailments, especially diabetes. In recent years, the interest in these plants has increased considerably in all world. This review shows the main chemical and pharmacological aspects of these plants. The studies carried out with the extracts and purified compounds from these plants support most of their reported therapeutic properties. It also gives an account of some compounds including terpenes, steroids and flavonoids that were isolated from the genus Bauhinia.

Gênero Baccharis (Asteraceae): aspectos químicos, econômicos e biológicos

The Baccharis genus is represented by more than 500 species distributed mainly in the tropical areas of South America. Many of them are extensively used in folk medicine in the treatment or prevention of anemias, inflammations, diabetes and stomach, liver and prostate diseases. Phytochemical and biological investigations in about 120 species resulted mainly in the isolation of clerodane and labdane diterpenes and flavonoid aglicones with the flavone unit being the most frequent.

Potencial antimicrobiano e alelopático das amidas isoladas do extrato das raízes de Ottonia martiana Miq.

Two amides, piperovatine and isopiperlonguminine, were isolated from the roots of Ottonia martiana Miq., a herbaceous shrub commonly used in folk medicine in the treatment of toothache. The crude extract (CE) and isolated compounds were submitted to bioautography and allelopathic assay. The bioautograms allowed the detection of compounds with antibacterial activity and the identification of the bioactive substance piperovatine. The CE and amides exhibited an allelopathic effect on Lactuca sativa (lettuce) seedling growth but did not affect the seeds' germinability.

Preparative separation of flavonoids from the medicinal plant Davilla elliptica St. Hill. by high-speed counter-current chromatography

High-speed counter-current chromatography (HSCCC) is a major tool for the fast separation of natural products from plants. It was used for the preparative isolation of the flavonoid monoglucosides present in the aerial parts of the Davilla elliptica St. Hill. (Dilleniaceae). This species is used in Brazilian folk medicine for the treatment of gastric disorders. The optimum solvent system used was composed of a mixture of ethyl acetate-n-propanol-water (140:8:80, v/v/v) and led to a successful separation of quercetin-3-O-alpha-L-rhamnopyranoside and myricetin-3-O-alpha-L-rhamnopyranoside in approximately 3.0 hours with purity higher than 95%. Identification was performed by ¹H NMR, 13C NMR and HPLC-UV-DAD analyses.

Ácido 15-desmetilisoplumierídeo, um novo iridóide isolado das cascas de Plumeria rubra e do látex de Himatanthus sucuuba

Himatanthus sucuuba and Plumeria rubra are used in folk medicine in Brazil to treat various ailments. The isolation of the new iridoid 15-demethylisoplumieride from the bark of Plumeria rubra L. var. acutifolia (Ait) Woodson and latex of Himatanthus sucuuba (Spruce) Woodson is reported. Other iridoid glycosides were obtained from both plants. The structures of these substances were elucidated by spectral analysis and comparison with data already reported.

Diterpenos casbanos e acetofenonas de Croton nepetaefolius (Euphorbiaceae)

Croton nepetaefolius is an aromatic plant native to the northeast of Brazil where it is extensively used in folk medicine as a sedative, orexigen and antispasmodic agent. The present work deals with the chromatographic analysis of the ethanolic extract of Croton nepetaefolius stalk. It allowed the isolation and characterization of two diterpenoids named 1,4-dihydroxy-2E,6E,12E-trien-5-one-casbane and 4-hydroxy-2E,6E,12E-5-one-casbane, two acetophenones named 2-hydroxy-4,6-dimethoxyacetophenone and 2-hydroxy-3,4,6-trimethoxyacetophenone and the steroids 3-O-b-D-glucopiranosylsitosterol and a mixture of b-sitosterol and stigmasterol. Structural elucidation was done on the basis of spectral data, mainly high field NMR and EIMS.
