Sage (Salvia officinalis L.) is an important medicinal and aromatic herb, used as a raw material for various perfumery, pharmaceutical, food, and cosmetics industries. S. officinalis belonging to the family Lamiaceae is commercially cultivated for the essential oil and is grown throughout Europe and the United States, and in parts of Turkey, Yugoslavia, and Canada. Leaves are highly aromatic, used for extraction of essential oil, which contains more than 49 aromatic components. The principal components in the sage oil are 1, 8-cineole, camphor, α-thujone, β-thujone, α-humulene, rosmarinic acid, and quercetin. Traditionally garden sage has been used for the treatment of a multitude of ailments such as localized pain, rheumatism, convulsion, arthritis, vertigo, diarrhea, sclerosis, respiratory, metabolic and mental disorders. As the herbal medicines gaining importance in recent years, usage and systematic documentation of such herb are found essential. Thus an effort has been made to ...

Even though Salvia genus is one of the most known and studied taxa of Lamiaceae family, the knowledge regarding the chemical composition and health-related benefits of some locally used Salvia species (mostly endemic) is still scarce. In this regard, the present work aims to evaluate the chemical profile and potential bioactivities of 70% (v/v) ethanolic extracts obtained from the less-studied S. transsylvanica and S. glutinosa in comparison with S. officinalis. HPLC-PDA analysis revealed the presence of rutin and catechin as the main compounds in the extracts of the three studied species (using the employed HPLC method), whereas the presence of naringenin was highlighted only in S. glutinosa extract. Chlorogenic acid, rutin and quercetin were identified and quantified for the first time in S. transsylvanica extracts. The in vitro antioxidant capacity of each extract was tested through complementary methods (phosphomolybdenum assay, DPPH, ABTS, CUPRAC and FRAP assays), and correlate...

Aim of the study: This study was performed to determine the essential oil components of Salvia tomentosa Mill., Salvia argentea L. and Salvia bracteata Bank et Sol. Area of study: The study was carried out in two districts (Eğirdir and Şarkikaraağaç) located at Isparta province in Turkey. Material and methods: The isolation of essential oil components was performed from shoots with leaves and flowers. Qualitative analysis of essential oils was carried out by using a Shimadzu 2010 Plus GC-MS device. The identification of the constituents was carried out by comparing the retention index (RI) and mass spectral data (MS) to those reported in the literature. Main results: As a result of the GC-MS analysis, the major components of the essential oil were (-)caryophyllene oxide (49.56%), β-vatirenene (7.87%), and α-Muurolol (6.78%) in S. tomentosa, sclareol (40.01%), germacrene-D (13.93%) and β-pinene (11.93%) in S. argentea and eucalyptol (1,8-cineole) (16.6%), β-pinene (14.7%) and cembrene (10.88%) in S. bracteata. Sclareol, which was determined at a high concentration in S. argentea in this study, is an economically valuable component that is widely used as flavoring in food and tobacco industry and as a perfume ingredient in the cosmetic industry. Highlights: According to this study, the cultivation of S. argentea can provide high economic returns.
Composition of the essential oil of Salvia officinalis L. from various European countries
Natural Product Research, 2007
Variations in the essential oil composition of Sulvkr ofJicinulis L. growirtg in Estonia ancl in other European countries were determined. The oils rvere obtained in yields ol 2.2-24,8mLkg-r. In three samples, the content of essentiirl oil did not conform to the EP standarcl (l0mLkg-r). Varialions in the essential oil composition of serge were studied using capillary gas chromatographic methods. A total ol 40 comportents were identified. The principal colnponents in the sage oils rvere 1,8-cineole, ciunphor, a-thujone, p-thu.ione. borneol, and yiridiflorol. The chenotypes ol sage were not determined in investigated samples. The concentration of the rnain compounds in the drugs cultivated in Estonia varied in about the same ralnge as the concentrations ol'these compounds in the oils of drugs obtained fronr other countries. The comparatively high concentration oltoxic thujones seenl to be chirtacteristic to sage leaves cultivated in Estoniir.
Phytochemical Study And Biological Activity Of Sage (Salvia Officinalis L.)

This study presents an attempt to evaluate the<br> antioxidant potential and antimicrobial activity of methanolic extract,<br> and essential oils prepared from the leaves of sage (Salvia officinalis<br> L.). The content of polyphenol in the methanolic extracts from the<br> leaves of Salvia officinalis was determined spectrophotometrically,<br> calculated as gallic acid and catechin equivalent. The essential oils<br> and methanol extract were also subjected to screenings for the<br> evaluation of their antioxidant activities using 2, 2-diphenyl-1-<br> picrylhydrazyl (DPPH) test. While the plant essential oils showed<br> only weak antioxidant activities, its methanol extract was<br> considerably active in DPPH (IC50 = 37.29 μg/ml) test. Appreciable<br> total polyphenol content (31.25 mg/g) was also detected for the plant<br> methanol extract as gallic acid equivalent in the Folin–Ciocalteu test.<br> The plan...

Although the knowledge and use of several Salvia species (Salvia officinalis, Salvia fruticosa, and Salvia pomifera) can be dated back to Greek Era and have a long history of culinary and effective medicinal use, still there is a remarkable interest concerning their chemistry and especially the polyphenolic composition. Despite the demand in the food and pharmaceutical industry for methods for fast quality assessment of the herbs and spices, even now there are no official requirements for the minimum content of polyphenols in sage covered by current regulations neither the European Pharmacopoeia monographs nor the ISO 11165 standard. In this work a rapid analytical method for extraction, characterization and quantification of the major polyphenolic constituents in Sage was developed. Various extractions (infusion - IE; ultrasound-assisted extraction - USE and microwave-assisted extraction - MWE) were performed and evaluated for their effectiveness. Along with the optimization of the mass-detector and chromatographic parameters, the applicability of three different reverse C18 stationary phases (extra-density bonded, core-shell technology and monolith column) for polyphenolics characterization was evaluated. A comprehensive overview of the very variable polyphenolic composition of 118 different plant samples of 68 populations of wild growing culinary Salvia species (S. officinalis: 101; S. fruticosa: 15; S. pomifera: 2) collected from South East Europe (SEE) was performed using HPLC-DAD-ESI-MS(n) and more than 50 different compounds were identified and quantified. With this work the knowledge about polyphenols of culinary Sage was expanded thus the possibility for gaining an insight into the chemodiversity of culinary Salvia species in South East Europe was unlocked.
