Antibacterial Activity of Salvia reuterana Constituents
Authors: not saved
Abstract:
Two flavonids: 5-hydroxy-6,7,4 ́-trimethoxy flavone (salvigenin), 5-hydroxy-7,4 ́-dimethoxy flavone(thitonine) and a labdane type diterpenoid: 8,13-epoxy-14 labdene (manoyl oxide) isolated from the solventextract of the aerial part of Salvia reuterana Boiss.The proposed structure were stablished by 1HNMR,13CNMR, 2DNMR( C-H-Cosy, HMQC),DEPT and Mass spectroscopy and confirmed in accordance withbibiliographic data and computational chemistry results. The three components were evaluated against 7microorganisms including gram(+/-)bacterias by measurment of growth inhibitory zone. They showedsignificant effect specially on gram(-) bacterias and in this way the most effective component was thitoninewhich was even more effective than Gentamicine as standard antibiotic.

full textAntimicrobial activity of six constituents of essential oil from Salvia.
The antimicrobial activity of three Salvia species, i.e. S. santolinifolia, S. hydrangea and S. mirzayanii, essential oils were investigated. The essential oils were obtained from the aerial parts of plants and analyzed by GC-MS. The main constituents of aforementioned species were alpha-pinene (72.4%), beta-pinene (6.6%) and limonene (5.3%); beta-caryophyllene (25.1%), 1,8-cineol (15.2%) and c...

The essential oil of Salvia aegyptiaca was analysed by GC/ MS technique. Eighteen compounds were identified. It was found that the essential oil comprises 40% terpenoidal constituents, opposite to 32% fat derivatives. The major terpenoidal component was 1(10)aristolene (19.3%). From the non-volatile matter, β-amyrin, lupeol, β-sitosterol, stigmasterol, β-sitosterol-β-D-glucopyranoside and stigm...

Objective: The present stu...
full textNew diterpenoids from the aerial parts of Salvia reuterana
The genus Salvia is a valuable origin of structurally diverse terpenoids. In a project directed at structurally interesting bioactive metabolites from Iranian Salvia species, we studied Salvia reuterana. Two new labdane diterpene, 6β,14α-dihydroxy-15-acetoxysclareol (1), and 14α,15- dihydroxy sclareol (2), were isolated from the aerial part of the plant. Their structures were established mainly...
