Taxodione, a diterpenoid from the roots of Salvia chorassanica Bunge, possesses cytotoxic, apoptotic, and antimicrobial activity. This study was designed to investigate the protective effects of taxodione on serum/glucose deprivation-induced ischemic injury in PC12 cells and related mechanisms. In
Taxodione, an abietane diterpenoid, was isolated from Salvia austriaca transformed roots grown in in vitro conditions. The compound is known to have antibacterial, cytotoxic and anti-tumour properties. This study evaluates the ability of pure taxodione and extracts obtained from the S. austriaca
From a root culture of Salvia austriaca, transformed with Agrobacterium rhizogenes, a new diterpenoid was isolated and its chemical structure was determined as 7-(2-oxohexyl)-11-hydroxy-6, 12-dioxo-7,9(11),13- abietatriene [= 7-(2-oxohexyl)-taxodione] on the basis of spectroscopic methods,
The aim of the present report was to evaluate antimicrobial/anti-biofilm activity of 7-(2-oxohexyl)-taxodione, a novel taxodione derivative isolated from n-hexane extract of Salvia austriaca hairy roots. Antimicrobial assays showed that 7-(2-oxohexyl)-taxodione was at least 4 times more active than
Four diterpenes with biological activity were isolated from Salvia deserta roots. Taxodione was considered leishmanicidal with an IC50 value of 1.46 µM (0.46 mg/L) against Leishmania donovani and also exhibited antifungal and antimicrobial activities. Ferruginol displayed the greatest activity [24-h
One new triterpenoid olean-18-ene-1β, 2α, 3β-triol (1) along with four known compounds were isolated from the chloroform extract of the aerial part of Salvia atropatana Bunge. The known compounds were two flavonoids, 5-hydroxy-7,4'-dimethoxyflavone (2) and 5-hydroxy-6,7,4'-trimethoxyflavone (3), an
From the chloroform extract of the aerial parts of Salvia xanthocheila, one new triterpene, together with two known diterpenes, two known flavonoids and a phytosterol was isolated. On the basis of comprehensive spectroscopic analyses, including electron ionisation mass spectra, ¹H-NMR, ¹³C-NMR, 1-D
From the roots of Salvia prionitis, a novel alkaloid named prioline (1) and a new diterpene, prineoparaquinone (2), were isolated together with taxodione; microstegiol; 8,11,13-dehydroabietane; and 2-isopropyl-8-methyl-3,4-phenanthraquinone. The structures of the new compounds were established by
A new ursane-type triterpenoid, 3 beta,11 alpha,21 alpha-trihydroxyurs-12-ene, named salvistamineol (1), has been isolated from the methanol extract of Salvia staminea. In addition to 1, the methanol extract yielded four known compounds and the acetone extract yielded twelve known compounds
BACKGROUND
The phytochemical and biological studies carried out on Salvia species showed that their extracts and constituents have various biological activities.
OBJECTIVE
The aim of this study was the isolation of diterpenoids from the roots of Salvia barrelieri Ettling and the determination of the
Bioassay-guided fractionation of Salvia chorassanica Bunge roots for the first time led to the isolation of taxodione, ferruginol and 6-hydroxysalvinolone. Cytotoxic studies revealed that all compounds exhibited high cytotoxic activity against apoptosis-proficient HL-60 and apoptosis-resistant K562
The new diterpenes brussonol (1) and iguestol (6alpha,11-dihydroxy-12-methoxy-abieta-8,11,13-triene) (2) with an icetexane and a dehydroabietane skeleton, respectively, have been isolated from hairy root cultures of Salvia broussonetii. Other previously known diterpenes, 7-oxodehydroabietane,
Hairy roots of Salvia austriaca Jacq. transformed with Agrobacterium rhizogenes strain A4 were obtained and transgenic status of the roots was confirmed by polymerase chain reaction (PCR) using rolB and rolC specific primers. The root cultures growing in half-strength Gamborg (1/2 B5) liquid medium
The biomass and concentration of bioactive quinone methide-type diterpenes in hairy roots of Salvia austriaca were determined and compared with levels of these metabolites in roots of field-grown plants. The cultures were maintained in shake flasks and a nutrient sprinkle bioreactor. Diterpene
