Coumarins and essential oils are the major components of the Apiaceae family and the Zosima genus. The present study reports anticholinesterase and antioxidant activities of extracts and essential oils from aerial parts, roots, flowers, fruits and coumarins—bergapten (1); imperatorin (2), pimpinellin (3) and umbelliferone (4)—isolated of the roots from Zosima absinthifolia. The investigation by light and scanning electron microscopy of the structures of secretory canals found different chemical compositions in the various types of secretory canals which present in the aerial parts, fruits and flowers. The canals, present in the aerial parts, are characterized by terpene hydrocarbons, while the secretory canals of roots, flowers and fruits include esters. Novel data of a comparative study on essential oils constituents of aerial parts, roots, flowers and fruits of Z. absinthfolia has been presented. The roots and fruits extract showed a high content of total phenolics and antioxidant activity. The GC-FID and GC-MS analysis revealed that the main components of the aerial parts, roots, flowers and fruits extracts were octanol (8.8%), octyl octanoate (7.6%), octyl acetate (7.3%); trans-pinocarvyl acetate (26.7%), β-pinene (8.9%); octyl acetate (19.9%), trans-p-menth-2-en-1-ol (4.6%); octyl acetate (81.6%), and (Z)-4-octenyl acetate (5.1%). The dichloromethane fraction of fruit and flower essential oil was characterized by the highest phenolics level and antioxidant activity. The dichloromethane fraction of fruit had the best inhibition against butyrylcholinesterase enzyme (82.27 ± 1.97%) which was higher then acetylcholinesterase inhibition (61.09 ± 4.46%) of umbelliferone. This study shows that the flowers and fruit of Z. absinthifolia can be a new potential resource of natural antioxidant and anticholinesterase compounds.

Ethnobotany is briefly defined as a"human-plant relationship". Mankind has used plants as a food source since ancient times, resorted to healing and accumulated their experiences. About 12.000 plant species grow in Turkey. The World Health Organization (WHO) has determined the number of herbal medicines as approximately 1900 and it has been determined that approximately 20,000 plants are grown in Turkey, 600 of which are used for therapeutic purposes. This investigation was conducted to document the species, family, and local names, usage types and localities of medicinal plants utilized by people living in and around Ardahan, Iğdır and Kars provinces between 2020-2021 for dermatologic disorders. To that end, medicinal plant species utilized by the local mankind for therapeutic aims were collected and detected. The visitations were organised to the investigation regions at regular intervals, and survey investigations were realized by interviewing and talking with the local people one-on-one. 82 medicinal plant taxa belonging to 31 plant families utilized in dermatologic disorders were collected from Ardahan, Iğdır and Kars provinces and their surroundings. Of these, 68 species are wild and 14 are cultivated plants. It has been reported that the most commonly utilized medicinal plant families in dermatologic disorders are Asteraceae (12), Scrophulariaceae (7), Boraginaceae (5), Fabaceae (5), and Salicaceae (5). As a conclusion, despite the deep-rooted history in such regions, the transmission and use of traditional knowledge have remained limited.
