Herbal teas are widely consumed in Turkey. This study aimed to evaluate the antimicrobial activity of methanol, acetone, and aqueous extracts endemic Sideritis galatica plant collected from Afyonkarahisar. For this purpose, effect different concentrations (2.5%, 5%, 10%, 20%) these on L. monocytogenes, B. cereus, S. aureus, E. faecalis, coli, coli O157, typhimurium, C. albicans were investigate...

A sterol fraction composed of campesterol (7.6%), stigmasterol (28.4%) and beta-sitosterol (61.1%) was obtained by activity-guided fractionation of the acetone extract of Sideritis foetens Clem. This sterol fraction showed anti-inflammatory activity in in vivo murine models of inflammation. It decreased carrageenan paw oedema in mice after oral administration of 30 and 60 mg/kg and inhibited mo...

The following aromatic plants of Greek origin, Origanum dictamnus (dictamus), Eucalyptus globulus (eucalyptus), Origanum vulgare L. (oregano), Mellisa officinalis L. (balm mint) and Sideritis cretica (mountain tea), were examined for the content of phenolic substances. Reversed phase HPLC coupled to diode array detector (DAD) was used for the analysis of the plant extracts. The gas chromatograp...

Two ent-18-acetoxy-6-oxomanoyl oxides, epimers at C-13, have been prepared from ent-6alpha,8alpha,18-trihydroxylabda-13(16),14-diene (andalusol), isolated from Sideritis foetens, by means of several chemical pathways and a regioselective acylation with Candida cylindracea lipase (CCL). Biotransformation of these 13-epimeric ent-manoyl oxides by Fusarium moniliforme and Neurospora crassa produce...

Sideritis leucantha Cav. subsp. es un endemismo valenciano con uso medicinal que tiene diversos problemas de conservación. Por tanto, el objetivo principal este trabajo fue probar efecto tratamiento precultivo para la posterior criopreservación brotes apicales esta especie. Los resultados mostraron sacarosa 0.3 M durante 24 horas result en una mayor supervivencia los explantes y regeneración in...
