Plants with antidiabetic activities provide important sources for the development of new drugs in the treatment of diabetes mellitus. In the present study, we investigated possible antihyperglycemic and antioxidative activities of the aerial part of the Matricaria chamomilla L. ethanolic extract (MCE) in streptozotocin (STZ; 70 mg/kg, i.p.)-induced diabetic rats. The following groups were assigned; sham (did not receive any substance), STZ + distilled water (control), STZ + 5 mg/kg glibenclamide, STZ + 20 mg/kg MCE, STZ + 50 mg/kg MCE, STZ + 100 mg/kg MCE. Diabetic rats were treated for 14 days by gavage. Postprandial blood glucose levels, malondialdehyde, reduced glutathione (GSH), nitrate, nitrite, ascorbic acid, retinol, beta-carotene, superoxide dismutase, and catalase levels were measured, and immunohistochemical studies were performed in all of the groups. The obtained data showed that STZ resulted in oxidative stress and affected the antioxidant status. Treatment with different doses of MCE significantly reduced postprandial hyperglycemia and oxidative stress, and augmented the antioxidant system. In histological investigations, MCE treatment protected the majority of the pancreatic islet cells, with respect to the control group. As a result, MCE exhibited significant antihyperglycemic effect and protected beta-cells in STZ-diabetic rats, in a dose-dependent manner, and diminished the hyperglycemia-related oxidative stress.

This study is focused on ethnobotanical usages of wild plants growing within the Afyonkarahisar province districts of Sinanpaşa, Hocalar and Dazkırı. Ninety local informants in 11 villages were interviewed. A total of 129 different usages of wild plants in the study area were recorded. Out of 650 plant species commonly present, 93 plant taxa (14.3%) belonging to 43 families were used for medicinal (52 citations), foodstuff (37 citations), fodder (14 citations), dye (six citations), firewood (five citations), construction materials (four citations) and miscellaneous purposes (11 citations). At least 15% of the information regarding ethnobotanical uses of wild plants was obtained by showing herbarium voucher samples to the informants. It was noted that Sideritis leptoclada and Verbascum stenostachyum are endemic to Turkey and their endangered status has markedly increased in recent years because of increased collecting for ethnobotanical purposes. Informants indicate that members of the younger generation have a much reduced interest in ethnobotanical knowledge and that this is a danger to the continued use of local plants.

In recent years, people have been exposed to several types of substances with broad spectrum due to the rapidly evolving technology. One of these chemical substance groups are pesticides. Pesticides have been an essential part of agriculture to protect crops and livestock from pest infestations and yield reduction for many decades. Despite their usefulness, pesticides could pose potential risks to food safety, the environment, and all living things. Concern about the environmental impact of repeated pesticide use has prompted research into the environmental fate of these agents, which can emigrate from treated fields to air, other land, and water bodies. The importance of agricultural pesticides for developing countries is undeniable. However, the issue of human health and environmental risks has emerged as a key problem for these countries in accordance to a number of studies. In the last five decades, pesticide usages increased the quantity and improved the quality of food. However, with the increasing amounts of their usage, concern about their adverse effects on nontarget organisms, including human beings, has also grown. The purpose of this publication is to explain the nature of pesticides and their history, classification, risks, and effects on health and the environment.

This study investigates ethnobotanical uses of wild plants found on Honaz Mountain and its vicinity in Denizli Province in the middle Aegean region of Turkey. Eighty-one persons from 13 villages and six townships were interviewed. Nine hundred and sixty-four species, belonging to 60 plant families, were identified for which 381 different uses were recorded. Informants reported ethnobotanical uses for 19% of the identified species (184 out of 964): food (65), fodder (111), medicinal (119), firewood (28), handicrafts (16) and various other purposes (26). Medicinal tar production was particularly noted.

BackgroundThe traditional knowledge about plants and their uses in Turkey is disappearing in recent years because the new generations of villagers migrate to big cities for a better life. Afyonkarahisar located at the intersection of roads and phytogeographical regions (Mediterranean, Iran-Turan, and Euro-Siberian) has more than 2500 plant species. This richness of plant diversity promotes the indigenous commuity for the traditional use of wild plants. The aim of the study is to show wild plants’ ethnobotanical usages associated with medicinal, food, fodder, and household goods in 31 settlements within the boundaries of Afyonkarahisar province.MethodsThe ethnobotanical data were collected from 46 informants by means of semi-structured interviews from 2012 to 2014. Ethnobotanical uses of plants of the study area were conducted in the vicinity of Afyonkarahisar (5 districts, 8 towns, 15 villages, and 3 neighborhood centers).ResultsOne hundred and thirty plant taxa belonging to 39 families were recorded and collected. Hundred and seventy-eight different uses of these plants were documented and used generally for medicinal (84), food (68), fodder (16), household goods (3), dyes (3), handicrafts (3) and religious (1).ConclusionThis study provides interesting uses of plants in the local community of Afyonkarahisar and its surrounding area, in what purpose they make use of plants, how they make use of them and obtained results will contribute to economy of villagers. Since the local people, especially in villages, are poor and do not have health care, they use the plants to treat illnesses, food, fodder, household goods and other uses (evil eye). Also this study will light the way for posterity for next generations.
