Biotransformation of (-)-alpha-pinene by Botrytis cinerea
(Verlag Z Naturforsch, 2002)(-)-alpha-Pinene (1), a major constituent of many aromatic plants was biotransformed by the plant pathogenic fungus, Botrytis cinerea to afford three new metabolites, characterized as 3beta-hydroxy-(-)-beta-pinene (10%) ... -
Composition and antibacterial activity of the essential oils from Satureja wiedemanniana (Lallem.) Velen
(Verlag Z Naturforsch, 2001)Satureja wiedemanniana (Lallem.) Velen (Lamiaceae) is an endemic species of Turkey. Aerial parts of the plant collected from eleven different localities in Turkey were subjected to hydrodistillation to yield essential oils ... -
Composition and the in vitro antimicrobial activities of the essential oils of some Thymus species
(Verlag Z Naturforsch, 2004)The genus Thymus (Lamiaceae) is represented by 38 species (64 taxa) in Turkey, and 24 of which are endemic to Turkey. Aerial parts of Thymus longicaulis subsp. chaubardii var. chaubardii, T zygioides var. lycaonicus, T ... -
Detoxification of terpinolene by plant pathogenic fungus Botrytis cinerea
(Verlag Z Naturforsch, 2002)Detoxification of an antifungal monoterpene terpinolene (1) by the plant pathogenic fungus Botrytis cinerea afforded hydroxlyated metabolites 2,3-dihydro-3beta,6beta-dihydroxy-terpinolene (2) (39%) and 2,3-dihydro-1alpha ... -
Isolation of Quality Total RNA from the Aromatic Plant Origanum onites
(Verlag Z Naturforsch, 2010)We successfully used the guanidine isothiocyanate method for isolation of total RNA from leaf, stem, and root tissues of the aromatic plant Origanum onites. The RNA was extracted with TRI Reagent (R) at room temperature ... -
The microbial oxidation of (-)-beta-pinene by Botrytis cinerea
