“…Previously, Mendili et al 20 showed that acetone extract of Tunisian lichen C. rangiformis had DPPH antioxidant capacity (IC 50 = 23.0 μg/mL). Kocakaya et al 21 found ABTS radical removal effect of the methanolic extract of C. rangiformis (2.50 mmol/L/Trolox). According to previous research, there is no data for the analysis of the ability of C. rangiformis acetone extract to neutralize ABTS radicals.…”

Introduction Cladonia rangiformis, also known as reindeer lichen, has been used for various remedies in folk medicine. The rich nutritional value of this lichen is reflected in the fact that it contains atranorin, which has been proven to have numerous biological activities. Objective The chemical composition, antioxidant, anticholinesterase, and antigenotoxic activities of the C. rangiformis acetone extract were investigated. The novelty of this work is that anticholinesterase activity, protective effect on human lymphocytes, and antioxidant activity by the cupric-reducing antioxidant capacity (CUPRAC) method of C. rangiformis extract were determined for the first time, as well as gas chromatography - mass spectrometry (GC-MS) profile. Methods Chemical composition was carried out by high-performance liquid chromatography (HPLC)-diode array detector and GC-MS. Antigenotoxic effect was evaluated in human lymphocytes by cytokinesis-block micronucleus assay. Total phenolic content, DPPH and ABTS radical scavenging capacities, CUPRAC, and total reducing power were determined spectrophotometrically. Determination of acetylcholinesterase activity was performed by Ellman's colorimetry assay. The statistical analysis of variance (One-way ANOVA) was performed using Origin software package version 7.0. Results HPLC method was used to identified 3 compounds with atranorin as predominant constituent (97.2%). Fumarprotocetraric and atraric acid were represented in a much smaller mutually approximate amount, 0.3 and 0.5%, respectively. Rangiformic acid was the most abundant volatile compound. Acetone extract of C. rangiformis (2 μg/mL) decreased the frequency of micronuclei by 15.5% while the radioprotectant amifostine reduced the frequency of occurrence of micronuclei by 11.4%. On the contrary, at a concentration of 1.0 mg/mL the extract exhibited an activating effect on cholinesterase (2.0%), while at a concentration of 10.0 mg/mL it showed a weak inhibitory effect (7.3%). The total phenol content was 132.71 μg gallic acid equivalents per mg of dry extract. The IC50 value for the DPPH experiment was 16.19 mg/mL and for ABTS was 11.80 mg/mL. Cupric reducing capacity and total reducing power were 17.81 μg Trolox equivalents per mg of dry extract and 0.45 μg ascorbic acid equivalents per mg of dry extract, respectively. Conclusion In addition to previously identified compounds in the acetone extract, atraric acid was identified for the first time by using HPLC method, and orcinol, β-orcinol, lauric alcohol, atranol, and rangiformic acid by using GC-MS method. The results of biological activity proved that acetone extract had antioxidant capacity and weak anticholinesterase activity. Reduction of the number of micronuclei in human lymphocytes, classified C. rangiformis as promising substances source with beneficial effects on DNA damage.

Çalışmanın amacı: Likenler, çeşitli elementler açısından hem doğal hem de yapay kaynaklı çevresel kirliliğin biyolojik göstergeleridir. Türkiye’nin farklı bölgelerinden toplanmış Cladonia cinsine ait 9 örnekte (Cladonia coniocraea, C. fimbriata, C. firma, C. foliacea, C. furcate, C. pocillum, C. pyxidata, C. rangiformis and C. subulata) Alüminyum, Krom, Mangan, Demir, Kobalt, Nikel, Bakır, Çinko, Arsenik, Selenyum, Stronsiyum, Kadmiyum, Kalay, Cıva ve Kurşun element miktarları araştırılmıştır. Çalışma alanı: Türkiye’de 7 farklı ilde yapılmış arazi çalışmalarında aynı cinse ait liken örnekleri toplanmıştır. Materyal ve yöntem: Tüm örnekler bağımsız olarak mikrodalga sistemde asit ortamında çözünürleştirildikten sonra ve üç paralel halinde analiz edilmiştir. Sonuçların doğruluğu, 1.547 Şeftali Yaprağı sertifikalı referans materyalin analiziyle onaylanmıştır. Temel sonuçlar: Metallerin kaynakları, metal birikim mekanizmaları ve likenler tarafından ne kadar absorblandıkları belirlenmiştir. Cladonia firma’da en yüksek Al, Cr, Ni konsantrasyonları sırasıyla 429.3, 3.04, 13.53 µg/g'dır. Cladonia subulata'da en yüksek Co, Sr, Cu, Se, Hg konsantrasyonları sırasıyla 0.81, 33.59, 13.16, 0.158, 0.060 µg/g'dır. Cladonia pyxidata'da en yüksek Pb, Cd, Sn konsantrasyonları sırasıyla 5.90, 0.30, 6.50 µg/g'dır. En yüksek Fe, Mn, Zn, As konsantrasyonları sırasıyla 228.7, 17.8, 26.44, 1.335 µg/g'dır. Araştırma vurguları: Sonuçlar likenlerde metal birikiminin doğrudan likenlerin toplandığı ortamla ilişkili olduğunu göstermiştir.

The present study evaluated the DNA protective properties and antimicrobial activities of the methanol extracts of nine Cladonia species, namely C. pocillum, C. subulata, C. pyxidata, C. coniocraea, C. foliacea, C. firma, C. furcata, C. fimbriata and C. rangiformis collected in Turkey. DNA protection properties efficiency of Cladonia extracts was evaluated using pBR322 plasmid DNA. In vitro antimicrobial activities of methanol extracts against two Gram-negative bacteria (Escherichia coli and Proteus mirabilis), three Gram-positive bacteria (Staphylococcus aureus, Micrococcus luteus and Bacillus subtilis) and two fungal strains (Candida glabrata and Candida albicans) were examined using the disc diffusion method and through the determination of minimal inhibitory concentrations (MIC). DNA protective studies, all Cladonia extracts protected pBR322 plasmid DNA against damage caused by the hydrogen peroxide (H2O2) with ultraviolet (UV). The results demonstrated that the inhibition zones in the disc diffusion method ranged from 6.5 to 19.0 mm. MIC results were ranged from 3.12 to 6.25 mg/mL. Cladonia extracts show a better antimicrobial effect against bacterial strains than fungal strains. The highest antimicrobial effect among lichen species was demonstrated by Cladonia pocillum. Our results demonstrated that tested Cladonia extracts had strong antibacterial and DNA protective effects. This is the first comprehensive study to evaluate the DNA protective properties activity of Cladonia extracts.
