Chemical and genetic relationships among sage ( Salvia officinalis L.) cultivars and Judean sage ( Salvia judaica Boiss.).
The essential oil composition and genetic variability of common sage ( Salvia officinalis L.) and its three ornamental cultivars ('Purpurascens', 'Tricolor', and 'Kew Gold') as well as Judean sage ( Salvia judaica Boiss.) were analyzed by GC-FID, GC-MS, and random amplified polymorphic DNA (RAPD). Common sage and its cultivars contained the same volatile compounds; only the ratio of compounds d...
متن کاملPhytochemical Study and Biological Activity of Sage (Salvia officinalis L.)
This study presents an attempt to evaluate the antioxidant potential and antimicrobial activity of methanolic extract, and essential oils prepared from the leaves of sage (Salvia officinalis L.). The content of polyphenol in the methanolic extracts from the leaves of Salvia officinalis was determined spectrophotometrically, calculated as gallic acid and catechin equivalent. The essential oils a...
متن کاملAntioxidative Phenolic Compounds from Sage (Salvia officinalis)
Ten phenolic compounds were isolated from a butanol fraction of sage extracts. Their structures were determined by spectral methods (NMR, MS, IR). Among them, a novel compound, 4-hydroxyacetophenone-4-O-â-D-apiofuranosyl-(1f6)-O-â-D-glucopyranoside, was identified. Two test systems, DPPH free radical scavenging activity and radical cation ABTS•+ scavenging activity, were used to evaluate their ...
متن کاملComparison of Conventional and Ultrasound-assisted Extraction Techniques on Mass Fraction of Phenolic Compounds from Sage (Salvia officinalis L.)
Sage (Salvia officinalis L.) is a popular herb which is native to the Mediterranean region and cultivated worldwide. Sage is an important source of antioxidants used as preservatives and has wider implications for the dietary intake of natural antioxidants.1,2 This antioxidant effect has been attributed to the main phenolic components, caffeic acid dimer – rosmarinic acid1 and flavonoids, being...
