This study aims to identify medicinal plants traditionally used to treat diseases by local people living in Güce district, north-eastern Turkey. The study was carried out between 2018 and 2021 using a two-part semi-structured, open-ended questionnaire with 165 local people. Data were analysed using use-report, frequency of citation, and informant consensus factor. Informants identified 128 vascular medicinal plant taxa belonging to 54 families and 106 genera. The most common plant taxa belong to Rosaceae (16 taxa/12.5%), Asteraceae (12 taxa/9.4%), and Lamiaceae (9 taxa/7%) families. The most frequently used preparation method reported was decoction (39.8%); the most commonly utilized plant parts were leaves (40.3%). Statistical analysis reveals that women in Güce district (df = 163, p = 0.043 < 0.05) possess the most traditional knowledge. The highest frequency of citation (61) and use report (92) were recorded for Tilia rubra subsp. caucasica, and the highest informant consensus factors were cited for respiratory system disorders (0.86), digestive system disorders (0.73), and skin disorders (0.71). This study reported nine plant taxa as medicinal plants for the first time, and documented a total of 293 new therapeutic uses. However, the study indicates that the transfer of traditional knowledge to future generations is limited (F = 3.355, p = 0.020). Action should be taken as soon as possible to preserve existing traditional knowledge and to ensure its transfer to future generations.

In this study, methanol extracts (MEs) and essential oil (EO) of Angelica purpurascens (Avé-Lall.) Gill obtained from different parts (root, stem, leaf, and seed) were evaluated in terms of antioxidant activity, total phenolics, compositions of phenolic compound, and essential oil with the methods of 2,2-azino-bis(3ethylbenzo-thiazoline-6-sulfonic acid (ABTS•+), 2,2-diphenyl-1-picrylhydrazil (DPPH•) radical scavenging activities, and ferric reducing/antioxidant power (FRAP), the Folin–Ciocalteu, liquid chromatography−tandem mass spectrometry (LC−MS/MS), and gas chromatography-mass spectrometry (GC−MS), respectively. The root extract of A. purpurascens exhibited the highest ABTS•+, DPPH•, and FRAP activities (IC50: 0.05 ± 0.0001 mg/mL, IC50: 0.06 ± 0.002 mg/mL, 821.04 ± 15.96 µM TEAC (Trolox equivalent antioxidant capacity), respectively). Moreover, EO of A. purpurascens root displayed DPPH• scavenging activity (IC50: 2.95 ± 0.084 mg/mL). The root extract had the highest total phenolic content (438.75 ± 16.39 GAE (gallic acid equivalent), µg/mL)). Twenty compounds were identified by LC−MS/MS. The most abundant phenolics were ferulic acid (244.39 ± 15.64 μg/g extract), benzoic acid (138.18 ± 8.84 μg/g extract), oleuropein (78.04 ± 4.99 μg/g extract), and rutin (31.21 ± 2.00 μg/g extract) in seed, stem, root, and leaf extracts, respectively. According to the GC−MS analysis, the major components were determined as α-bisabolol (22.93%), cubebol (14.39%), α-pinene (11.63%), and α-limonene (9.41%) among 29 compounds. Consequently, the MEs and EO of A. purpurascens can be used as a natural antioxidant source.

Aim of study: With this study, it was aimed to determine some wild plants in the traditional uses in daily lives by local people for healing, treatment, food, spices, equipment, etc. purposes.Area of study: The study area was Kale and Acıpayam provinces in Denizli between April and October 2016.Material and Methods: Plant materials were provided from villagers and county of Kale and Acıpayam districts. In the identification of plants, "Flora of Turkey and the East Aegean Islands" and "List of Turkish Plants" were used. To determine this, totally 60 people were interviewed face to face. The Informants' Consensus Factor (FIC) and Use Value (UV) formulas were used to analyze the data.Main results: As a result of the surveys conducted with 60 people, 48 plant taxa belonging to 29 families have been identified. It has been determined that the plants with traditional use in the region are mostly used for the treatment of stomach disorders, respiratory diseases and pain relief. The most used parts of the plants have been leaves. The highest UV is Olea europaea L. var. sylvestris L. (0.65), and the lowest UV is Pulicaria dysenterica (L.) Bernh.. (0.05). The highest FIC value (0.86) is cold and flu.Research highlights: Although Viscum album subsp. austriacum (Wiesb.) Vollman has been found to be used for different diseases in the literature, its use as a vasodilator drug was first determined by this study.

This study is aimed at reporting some of the plants traditionally used in the treatment of diseases by the local people living in the centre of Torul district and its surrounding villages. A face-to-face two-part questionnaire survey was conducted with 82 local people. Identification of 29 taxa belonging to 18 families has been confirmed and their medicinal uses have been recorded. In addition, the usage patterns of plant parts andpurposes are recognized. Plants are mostly used in the treatment of cold and flu, stomach disorders, gynecological, cardiovascular, and respiratory diseases. The highest use value (UV) was recorded for Rosa canina (0.54) and Mentha longifolia subsp. longifolia (0.46) and the highest Informants Consensus Factor (FIC) was cited for cold and flu (0.83) followed by stomach disorders (0.75). New information for folklore medicines have been collected from the study area.
