Seasonal chemical evaluation of Miconia chamissois Naudin from Brazilian Savanna
Ferreira, Juliana de Freitas; Mera López, Manuel Humberto; Gomes, João Victor Dutra; Martins, Diegue Henrique Nascimento; Fagg, Christopher WilliamMiconia chamissois Naudin is a species from the Cerrado, which is being increasingly researched for its therapeutic potential. The aim of this study was to obtain a standardized extract and to evaluate seasonal chemical variations. Seven batches of aqueous extracts from leaves were produced for the standardization. These extracts were evaluated for total solids, polyphenol (TPC) and flavonoid content (TFC), vit...
Lycorine alkaloid and Crinum americanum L. (Amaryllidaceae) extracts display an...
Silva, Lorene Coelho; Correia, Amabel Fernandes; Gomes, João Victor Dutra; Romão, Wanderson; Motta, Larissa Campos; Fagg, Christopher WilliamCandida species are the main fungal agents causing infectious conditions in hospital patients. The development of new drugs with antifungal potential, increased efficacy, and reduced toxicity is essential to face the challenge of fungal resistance to standard treatments. The aim of this study is to evaluate the in vitro antifungal effects of two crude extracts of Crinum americanum L., a rich alkaloid fraction a...
Influence of in vitro micropropagation on lycorine biosynthesis and anticholine...
Costa, Gabriella Gusmão Pereira da; Silva, Cristian Aldemar Gasca; Gomes, João Victor Dutra; Torres, Amanda Gomes; Santos, Izulmé Rita ImaculadaHippeastrum goianum (Ravenna) Meerow, Amaryllidaceae, is an endemic species from the Cerrado, Brazil; there are only few studies about its chemistry or biological activity. This study aimed to investigate the occurrence of lycorine in extracts from in vitro H. goianum plantlets, as well as evaluate a possible inhibition of acetylcholinesterase. The ethanol extract of plantlets produced by in vitro seed germinat...
