    Traditional phytotherapy and trans-cultural pharmacy among Turkish migrants living in Cologne, Germany
    (2005) Pieroni A.; Muenz H.; Akbulut M.; Başer K.H.C.; Durmuşkahya C.
    This article reports on an ethnopharmaceutical field study carried out among Turkish migrants in Cologne, western Germany, which recorded 79 botanical taxa and 115 plant-based preparations, encompassing 167 folk phytotherapeutical uses, as well as a few other biological (animal and mineral derived) remedies. One-fourth of the recorded remedies were represented by food-medicines. Half of the ingredients quoted came originally from Turkey; only a few plants were gathered from the wild or cultivated in the Cologne area. This article discusses the Turkish migrants' frequent use of aerial parts of Sideritis species, the fruits of Pistacia terebinthus and the seeds of Peganum harmala from the perspective of modern phytopharmacology, phytotherapy and toxicology. It considers cultural adaptation related to the use of folk pharmaceuticals by analysing the ingredients of the Turkish folk pharmacopoeia and comparing them with those of the Turkish medical ethnobotany and of the phytotherapy of the host country (Germany). Only one third of the remedies mentioned by Turkish migrants living in Cologne are also known in German evidence-based phytotherapy, and less than 10% of the recorded phytotherapeutic uses are common to both pharmacopoeias. This article concludes by suggesting hypotheses on future changes affecting the knowledge and use of medicinal plants within the Turkish community of Cologne. © 2005 Elsevier Ireland Ltd.

    Determination of the phytoalexin resveratrol (3,5,4′-Trihydroxystilbene) in peanuts and pistachios by High-Performance Liquid Chromatographic Diode Array (HPLC-DAD) and Gas Chromatography-Mass Spectrometry (GC-MS)
    (2005) Tokuşoǧlu Ö.; Ünal M.K.; Yemiş F.
    The phytoalexin resveratrol (3,5,4′-trihydroxystilbene) in edible peanut (Arachis hypogaea L.) and pistachio (Pistacia vera L.) varieties grown in Turkey was analyzed by high-performance liquid chromatographic diode array and gas chromatography-mass spectrometric detection. trans-Resveratrol in six peanut varieties, five pistachio varieties, and four market samples ranged between 0.03 and 1.92 μg/g. The Çerezlik 5025 peanut (1.92 ± 0.01 μg/g) and Ohadi pistachio genotype (1.67 ± 0.01 μg/g) had significantly higher trans-resveratrol contents. Peanuts contained 0.03-1.92 μg/g (av = 0.84 μg/g) of trans-resveratrol, whereas pistachio contained 0.09-1.67 μg/g (av = 1.15 μg/g). With exposure to UV light for 1 min, trans-resveratrol concentrations of samples ranged from 0.02 to 1.47 μg/g and those of cis-resveratrol from 0.008 to 0.32 μg/g. The occurrence of resveratrol in peanut and pistachio was confirmed by total ion chromatograms (TIC) of bis[trimethylsilyl]-trifluoroacetamide derivatives of resveratrol isomers and comparison of the mass spectral fragmentation data with those of a resveratrol standard. Formation of the cis-isomer in pistachios was higher than in peanuts. © 2005 American Chemical Society.
