Abstract
Prangos species were previously used against many disorders due to their chemical component. Prangos aricakensis Behçet & Yapar is a newly discovered local endemic species in Turkey's eastern region, and there is no research on P. aricakensis in the literature. In this work, oxypeucedanin and osthol molecules have been isolated from the root part of P. aricakensis for the first time. Oxypeucedanin and osthol structures were elucidated by 1D and 2D NMR analysis. For the bioactivities determination, antioxidant (DPPH· and ABTS·+ scavenging), enzyme inhibition (AChE, BChE, tyrosinase, and urease), antibacterial and DNA protection activity studies were applied for both molecules and compared with standard drug molecules, after applying enzyme kinetic assays and in silico approaches to clarify the mechanism of action for both molecules with enzymes, using molecular docking and density functional theory (DFT). Oxypeucedanin (2.19 ± 0.38 µg/mL) and osthol (4.57 ± 1.28 µg/mL) exhibited better activity than standards in DPPH∙ scavenging activity. Osthol (11.76 ± 0.59 µg/mL) showed a better tyrosinase inhibition effect than kojic acid (12.82 ± 0.91 µg/mL), and oxypeucedanin (3.03 ± 0.01 µg/mL) showed better urease inhibition effect than thiourea (5.37 ± 1.86 µg/mL). Our results showed that the osthol molecule was an excellent skin protective agent while the oxypeucedanin molecule could be a remarkable antiulcer agent. Therefore, although this study is the first in its field, it remained in the in vitro and in silico stages and is thought to pave the way for in vivo studies in the future.Communicated by Ramaswamy H.

Abstract
1,5,9-epideoxyloganic acid (ELA) was isolated from the aerial parts of endemic Nepeta aristata Boiss Et Kotschy Ex Boiss crude extract (methanol:chloroform) using silica gel (hexane, chloroform, ethyl acetate, and methanol) and sephadex LH-20 (65% methanol-35% chloroform) columns. Activity-guided isolation was performed on methanol sub-fractions with DNA protection and enzyme inhibitory activities, and then the ELA was purified by prep-HPLC. The ELA structure, bio-guided isolate, was determined via 1H NMR, 13C NMR, and MS spectrometry. ELA's enzyme inhibition and DNA protection activities were investigated and compared with standard drugs. The inhibition capacity of ELA against acetylcholinesterase (AChE), butyrylcholinesterase (BChE), urease, carbonic anhydrase (CA), α-glucosidase, α-amylase, lipase, and tyrosinase enzymes was evaluated by kinetic and molecular docking results. The ELA displayed the best inhibitory activity on AChE, BChE, α-glucosidase, urease, α-amylase, and tyrosinase with IC50 values of 2.53 ± 0.27, 3.75 ± 0.11, 3.98 ± 0.07, 4.40 ± 0.01, 6.43 ± 0.54 and 7.39 ± 0.00 µg/mL, respectively. ELA acted as a competitive inhibitor against BChE and α-glucosidase and a non-competitive inhibitor against AChE. The ELA's binding affinity values on AChE, BChE, and α-glucosidase were -7.70, -8.50, and -8.30 kcal/mol, respectively. DNA protection activity of the ELA molecule was determined as 57.53% for form I and 53.57% for form II. In conclusion, the inhibitory activity of ELA demonstrated its effectiveness in terms of its suitability in the pharmaceutical industry.Communicated by Ramaswamy H. Sarma.

Abstract
Ursolic acid (UA), which has many biological properties such as anti-cancer, anti-inflammatory and antioxidant, and regulates some pharmacological processes, has been isolated from the flowers, leaves, berries and fruits of many plant species. In this work, UA was purified from the methanol-chloroform crude extract of Nepeta species (N. aristata, N. baytopii, N. italica, N. trachonitica, N. stenantha) using a silica gel column with chloroform or ethyl acetate solvents via bioactivity-guided isolation. The most active sub-fractions were determined under bioactivities using antioxidant and DNA protection activities and enzyme inhibitions. UA was purified from these fractions and its structure was elucidated by NMR spectroscopy techniques. The highest amount of UA was found in N. stenantha (8.53 mg UA/g), while the lowest amount of UA was found in N. trachonitica (1.92 mg UA/g). The bioactivities of UA were evaluated with antioxidant and DNA protection activities, enzyme inhibitions, kinetics and interactions. The inhibition values (IC50) of α-amylase, α-glucosidase, urease, CA, tyrosinase, lipase, AChE, and BChE were determined between 5.08 and 181.96 µM. In contrast, Ki values of enzyme inhibition kinetics were observed between 0.04 and 0.20 mM. In addition, Ki values of these enzymes for enzyme-UA interactions were calculated as 0.38, 0.86, 0.45, 1.01, 0.23, 0.41, 0.01 and 2.24 µM, respectively. It is supported that UA can be widely used as a good antioxidant against oxidative damage, an effective DNA protector against genetic diseases, and a suitable inhibitor for metabolizing enzymes.Communicated by Ramaswamy H.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE This paper provides significant ethnobotanical information on medicinal plants in the villages of Çatak in the Eastern Anatolia Region. Recording such data calls for urgency. This is the first ethnobotanical study in which statistical calculations about plants are carried out by means of FIC method in Eastern (Van) part of Turkey. AIM OF THE STUDY This study aims to identify the wild plants collected for medicinal purposes by locals of Çatak which is located in the Eastern Anatolia Region of Turkey, and to identify the uses and local names of these wild plants. MATERIALS AND METHODS A field study had been carried out for a period of approximately 2 years (2010-2012). During this period, 78 plants taxa were collected. Demographic characteristics of participants, names of the local plants, their utilized parts and preparation methods were investigated and recorded. The plant taxa were collected within the scope of the study; and herbarium materials were prepared. In addition, the relative significance value of the taxa was determined, and informant consensus factor (FIC) was calculated for the medicinal plants included in the study. RESULTS We have found out in the literature review of the plants included in our study that 78 plant taxa are already used for medicinal purposes while 19 plants are not available among the records in the literature. The most common families are Asteraceae, Apiaceae, Lamiaceae, Rosaceae, Euphorbiaceae, Fabaceae, and Malvaceae. We include in our study and report for the first time the medicinal uses of Alchemilla buseriana Rothm., Astragalus longifolius Lam., Cephalaria microcephala Boiss., Euphorbia grisophylla M.S.

Abstract
BACKGROUND A detailed phytochemical analysis of Origanum vulgare L. ssp. viride (Boiss.) Hayek was carried out and the antioxidant activities of five different crude extracts were determined. The antiproliferative activities of the extracts were determined using the xCELLigence system (Real Time Cell Analyzer). RESULTS Differences between the essential oil and volatile organic compound profiles of the plant were shown. The main component of the essential oil was caryophyllene oxide, while the main volatile organic compounds were sabinene and eucalyptol as determined by HS-GC/MS. Phenolic contents of the extracts were determined qualitatively and quantitatively by HPLC/TOF-MS. Ten phenolic compounds were found in the extracts from O. vulgare and Origanum acutidens: rosmarinic acid (in highest abundance), chicoric acid, caffeic acid, p-coumaric acid, gallic acid, quercetin, apigenin-7-glucoside, kaempferol, naringenin and 4-hydroxybenzaldehyde. CONCLUSION This study provides first results on the antiproliferative and antioxidant properties and detailed phytochemical screening of O. vulgare ssp. viride (Boiss.) Hayek.

Abstract
Chenopodium album L. subs. album (Chenopodiaceae) is an annual herb with fibrous roots. The plant grows worldwide and frequently in moist areas. Sometimes, the young parts of this plant can be cooked and eaten as a vegetable. In this article, we report a mother and her adult son, in whom phototoxic reaction developed on the sun-exposed body areas after eating this plant of Chenopodiaceae family because of rare presentation. We thought that this reaction was probably due to furocoumarins constituent within the plant.
