The aim of this work was to determine the chemical composition of the ether, ethyl acetate and dichloromethane extracts of Ramalina capitata by GC-FID and GC-MS for the first time. The main identified components in the ether, ethyl acetate and dichloromethane extracts were everninic acid (24.7, 33.7 and 22.2%), orcinol (25.8, 16.7 and 11.9%), orcinol monomethyl ether (11.6, 7.6 and 4.8%), 3-methylorsellinic acid (10.2, 7.1 and 9.0%) and usnic acid (4.4, 8.2 and 25.8%), respectively. Considerable amount (10.4%) of 2-hydroxy-4-methoxy-3,5,6-trimethylbenzoic acid was detected in ethyl acetate extract. Additionally, palmitic acid, linoleic acid, oleic acid and stearic acid and their esters were observed in the dichloromethane and ethyl acetate extracts in the range of 4.1-0.1%, while their amount was below 0.05% in the ether extract. According to the results reported here R. capitata predominantly biosynthesises derivatives of orcinol and, in much lesser extent, derivatives of β-orcinol.

Introduction: Datura stramonium (DS) possesses strong medicinal and therapeutic potential but has been rarely evaluated in this context.
Methods: The present study was intended to evaluate the antioxidant, hepatoprotective, and nephroprotective potential of the crude methanolic leaf extract and ethyl acetate, chloroform, n-hexane, and aqueous fractions of DS in paracetamol-intoxicated rabbits. Paracetamol (2 g/Kg BW) was applied to induce liver and kidney injury in rabbits while the methanolic extract and fractions of DS were applied in the dose range of 150 mg/Kg to 300 mg/Kg body weight for 21 days.

In recent years, soil-transmitted helminthiases, including strongyloidiasis have become a prominent public health concern in the southeastern United States of America (USA). While there is ongoing human soil-transmitted helminths (STH) surveillance in Mississippi and Alabama, very little attention has been paid to potentially zoonotic STH from dogs in this region. We microscopically examined faecal samples collected from 252 shelter dogs in Mississippi using the formalin-ethyl acetate sedimentation method.
