Relationship of Camphor Biosynthesis to Leaf Development in Sage (Salvia officinalis).
The camphor content of sage (Salvia officinalis L.) leaves increases as the leaves expand, and the increase is roughly proportional to the number of filled peltate oil glands which appear on the leaf surface during the expansion process. (14)CO(2) is more rapidly incorporated into camphor and its direct progenitors in expanding leaves than in mature leaves, and direct in vitro measurement of th...
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 کاملChemical 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 کاملDetermination of the biologically active flavour substances thujone and camphor in foods and medicines containing sage (Salvia officinalis L.)
BACKGROUND The sage plant Salvia officinalis L. is used as ingredient in foods and beverages as well as in herbal medicinal products. A major use is in the form of aqueous infusions as sage tea, which is legal to be sold as either food or medicine. Sage may contain two health relevant substances, thujone and camphor. The aim of this study was to develop and validate an analytical methodology to...
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...
