“…Differences in activity concentrations may be due to differences in the geological location of plants and the radiochemical composition of the soils where these medicinal plants are grown or planted. Even in plants grown in the same region, the activity concentration levels of natural radionuclides may vary because some plants also absorb certain elements more than others 9 .…”

“…The extent to which roots absorb radionuclides from the soil does not only depend on their physiology but also on the processes within the soil 7 . The study of the concentration of radioactivity in plants in the environment is interesting in terms of ecological and plant development under certain geochemical point of view and adaptation conditions and therefore provides information in monitoring environmental radioactivity 8,9,10 . The aim of this study is to determine the natural radioactivity of some selected medicinal plants commonly used in Kars, Turkey and to evaluate the radiological risks associated with the use of these medicinal plants.…”

In Natural radioactive materials may be existing in the environmental substances that have uses in pharmacy and medicine as health supplements. In this study, natural radionuclides such as 226 Ra, 232 Th, and 40 K were measured in seven medicinal or herbal plants collected from the local market in Kars, Turkey were analysed. All samples were analysed by means of gamma-ray spectrometer using NaI(Tl) detector. The radioactivity concentrations were found to vary in the range of 16.39±2.2 to 32.76 ±3.5 Bqkg-1 for 226 Ra, 19.74±3.7 to 85.01±5.6 Bqkg-1 for 232 Th, and from 795.82±9.8 to 1056.28±14.4 Bqkg-1 for 40 K. Rosehip showed the lowest activity concentrations of 226 Ra, 232 Th and 40 K, while rumex patientia showed the highest activity concentration of 40 K. In this research study, we aimed to determine the activity concentrations of radionuclides in medicinal plants and provide useful information to carry out a dose assessment to be exposed to people using medicinal plants for healing various diseases.

“…There are many studies about the concentration of radioactivity in medical plants from different countries Desideri et a. (2010), Oni et al (2011), Tettey et al (2013 and Fahad et al (2014). There was clear data base on natural radioactivity levels in medical plant samples despite the wide intake of these kinds of plants as medical treatment.…”

In present study, natural levels of radiation in some selected medical plants existing in the Iraqi stores were estimated to determine any activity concentration, radium equivalent and internal hazard index due to radionuclide, of 238U, 232Th as well as 40K, which occurs naturally. This activity concentration was identified by gamma-ray spectroscopy (NaI(Tl)). The findings indicate that, the rate of activity concentration for Uranum-238, Thorium-232 and Potasium-40 in the medical plants were (4.953 0.37) Bq.kg -1 , (2.916 0.12) Bq.kg -1 and (219.134 2.24) Bq.kg -1 respectively. The values of the radium equivalent ranged from (6.081 0.09) Bq.kg -1 to (44.608 0.46) Bq.kg -1 with the rate of (20.278 0.38) Bq.kg -1 , while the values of the internal hazard index ranged from (0.016) to (0.135) with the rate of (0.060). The natural radionuclides and activity of the radium equivalent in the medical plant samples were far below the world for the ingestion of naturally occurring radionuclide provided in UNSCEAR 2000 report. Also there was calculated the internal hazard index for all samples that were less than unity. The samples under study were analysed and discharged, therefore they can no be consumed anymore.

“…Plants produce a wide array of secondary metabolites that are toxic to herbivore as well as to pathogen and it considered as defense molecules (Wittstock and Gershenzon, ). According to World Health Organization, plants are the best source for obtaining a variety of drugs and 70–80% of world populations depend upon medicinal plants (Tettey‐Larbi et al, ). Many traditional medicinal plants have proved to be toxic through in vivo toxicological studies (Atsamo et al, ).…”

Toxicity study of dibutyl phthalate ofRubia cordifoliafruits:in vivoandin silicoanalysis

Natural toxins from plant sources with wide ranges of biological activities reflect the upswing of drug design in the pharmaceutical industry. Rubia cordifolia L. is one of the most important red dye yielding plants. Most of the former researches have focused on the bioactive compounds from the roots of R. cordifolia, while no attention was paid towards the fruits. For the first time, here we report the presence of dibutyl phthalate in the fruits of R. cordifolia. Structural characterization was carried out using Ultraviolet-Visible spectrophotometer (UV-Vis), Fourier transform infrared (FTIR), gas chromatography-mass spectrophotometer (GC-MS), Nuclear magnetic resonance (NMR). Acute toxicity of the crude ethanolic extracts of the R. cordifolia fruits was examined in Swiss albino mice. No mortality was observed in all treated mice with 100, 500, 1000 mg/kg body weight of crude extract of R. cordifolia fruit and it indicates that the LD50 value is higher than 1000 mg/kg body weight. This study exhibited a significant change in the body weight. Alanine transaminase (ALT), total protein, triglycerides, glucose, and also the histopathological analysis of liver for all treated mice showed difference from the control group. The dibutyl phthalate was further evaluated for the toxicity study through in silico analysis. Together, the results highlighted that the toxic potential of R. cordifolia fruits extracts and also the toxicity profile of the fruit should be essential for the future studies dealing with the long term effect in animals. © 2015 Wiley Periodicals, Inc.
