Terpene synthases are responsible for the biosynthesis of the complex chemical defense arsenal of plants and microorganisms. How do these enzymes, which all appear to share a common terpene synthase fold, specify the many different products made almost entirely from one of only three substrates? Elucidation of the structure of 1,8-cineole synthase from Salvia fruticosa (Sf-CinS1) combined with ...

The identification and quantification of the phenolic contents of methanolic extracts of three Salvia L. species namely S. brachyantha (Bordz.) Pobed, S. aethiopis L., and S. microstegia Boiss. and Bal. were evaluated using reverse phase high performance liquid chromatography, UV adsorption, and mass spectrometry (RP-HPLC/MS). In order to determine the antioxidant capacity of these species, cup...

In the present research we investigated the anti-proliferative activity of Salvia menthifolia Ten. (formerly Salvia menthaefolia), Lamiaceae, on a glioblastoma cell line, since up to date poor therapeutic results have been reported for treatment of malignant glioblastoma. Methanol extracts from different anatomical parts of S. menthifolia were tested on DBTRG-05MG cell line by MTT assay. The mo...

Amplified fragment length polymorphism (AFLP) is a powerful fingerprinting technique that is widely applied in ecological and population genetic studies. However, its routine use has been limited by high costs associated with the optimization of fluorescently labelled markers, especially for individual study systems. Here we develop a low-cost AFLP protocol that can be easily transferred betwee...

OBJECTIVE To observe the effect of salvia miltiorrhizae injection on inflammatory mediator levels and mesenteric lymph nodes in severe acute pancreatitis (SAP) and obstructive jaundice (OJ) rats and explore the protective mechanism of salvia miltiorrhizae on the lymph nodes of these rats. METHODS A total of 288 rats were used in SAP-associated and OJ-associated experiments. The rats were rand...

PURPOSE we aim to explore the protective effects of Salvia miltiorrhizae injection on multiple organs of obstructive jaundice (OJ) rats through observing the impact of this injection on the pathological alterations in these organs and the contents of endotoxin, PLA(2), and TNF-alpha in the blood. METHODS A total of 90 mice were randomly divided into sham-operated group, model-control group, a...

essential oils are volatile, natural, complex compounds formed by aromatic plants as secondary metabolites. in nature, essential oils play an important role in protecting plants in form of antibacterials, antivirals, antifungals, insecticides properties and also against herbivores. they also may attract some insects to use them in dispersion of pollens and seeds, or repel undesirable others. pr...

Enhanced Expression of Genes Involved in the Biosynthesis Pathway Tanshinones Tetraploid Plants Salvia Officinalis L.

In petals of Salvia high concentrations of ether cause an increase in oxygen consumption and in the production of CO(2), while at the same time a decrease occurs in the acidity of the cell contents.
