Traditional uses of medicinal plants in Elazığ (Turkey)

ETHNOPHARMACOLOGICAL RELEVANCE

This study has identified not only the wild plants collected for medical purposes by local people of Elazığ Province in the Eastern Anatolia Region, but also the uses and local names of these plants. These resources are usually regarded as part of a culture׳s traditional knowledge. Therefore, the aim of this study is to collect information from local population concerning the use of medicinal plants of the Elazığ region; identify the most important medicinal plants used; determine the relative importance of the species surveyed and calculate the informant consensus factor (FIC) in relation to medicinal plant use.

MATERIALS AND METHODS

A field study had been carried out for a period of approximately 2 years (2012-2013). A questionnaire was administered to the local people, through face-to-face interviews (Appendix A). Demographic characteristics of participants, names of the local plants, their utilized parts and preparation methods were investigated and recorded. The plant species were collected within the scope of the study; herbarium materials were prepared; and the specimens were entitled. The collected data were used to calculate the FIC and the plant use values.

RESULTS

74 Plants were found to be used for medical purposes before in the literature analysis of the plants used in our study, while 6 plants were found to have no literature records. Our results showed that the highest use values were recorded for the species Urtica dioica L. (0.46) and Rosa canina L. (0.42), while the highest FIC was cited for skin diseases (0.60).

CONCLUSION

Data obtained showed that in the studied area the folk use of plants is alive and still derives from daily practice. Evaluation of pharmacological activity for the promising medicinal plants is suggested.

A preliminary study on 226Ra, 232Th, 40K and 137Cs activity concentrations in vegetables and fruits frequently consumed by inhabitants of Elazığ Region, Turkey

Determining radioactivity levels in foodstuffs is of great importance for the protection of human health. In addition, the literature includes few studies related to this subject in Turkey. In this study, gamma spectroscopic system was used in order to measure ²²⁶Ra, ²³²Th, ⁴⁰K and ¹³⁷Cs activity concentrations in vegetables and fruits produced in Elazığ Region. The average activity concentrations in vegetables was calculated as 0.64 ± 0.26 Bq kg⁻¹ for ²²⁶Ra, 0.65 ± 0.14 Bq kg⁻¹ for ²³²Th, 13.98 ± 1.22 Bq kg⁻¹ for ⁴⁰K, and 0.54 ± 0.04 Bq kg⁻¹ for ¹³⁷Cs. The average activity concentrations in fruits were 1.52 ± 0.34, 0.98 ± 0.23, 18.66 ± 1.13 and 0.59 ± 0.16 Bq kg⁻¹, respectively for ²²⁶Ra, ²³²Th, ⁴⁰K and ¹³⁷Cs. Total committed effective dose value was determined as 20 and 30.55 μSv y⁻¹, respectively for vegetables and fruits. The findings were compared with previous data reported for Turkey and other regions of the world.
