Usnea Longissima Ach. Liken Türününün Metanol Ekstresinin İn Vitro Sıçan Midesinde Mide Asit Sekresyonu Üzerine Etkisi

İzole Edilmiş Sıçan Midesinde Çörek Otu Sulu Ekstraktının Gastric Asit Sekresyonu Üzerine Etkileri

Nigella sativa (NS) has been shown to have antioxidant, anti-inflammatory and antiulcer activities in different conditions. The present work was done to investigate the possible effects of Nigella sativa aqueous extracts (NS) on gastric acid secretion in isolated rat stomach. Gastric acid secretion was measured in the isolated rat stomach preparation. The results obtained in vitro experiments s...

Secondary Metabolites Identification From Lichen Usnea longissima Ach. : Bioactivity Test of Antibacterial

Isolation and identification of secondary metabolite compound from chloroform fraction of Usnea longissima and its bioactivity test as an antibacterial had been conducted. The isolation of the chemical compound was performed by using Gravity Column Chromatography (GCC) and ThinLayered Chromatography (TLC). The result showed the needle crystal shaped isolated compound with translucent white colo...

Three New Non-reducing Polyketide Synthase Genes from the Lichen-Forming Fungus Usnea longissima

Usnea longissima has a long history of use as a traditional medicine. Several bioactive compounds, primarily belonging to the polyketide family, have been isolated from U. longissima. However, the genes for the biosynthesis of these compounds are yet to be identified. In the present study, three different types of non-reducing polyketide synthases (UlPKS2, UlPKS4, and UlPKS6) were identified fr...
