In this work we studied the effect of salinity (ranging from 50 to 500mM NaCl) on the physiological and the antioxidant responses of the local halophyte Limonium delicatulum Kuntze. We based our analysis on 12 biochemical assays that are commonly used to measure the antioxidant responses under

In saline biotopes, different mechanisms may contribute to the tolerance of halophytes to high soil salinity and temperature, drought and other abiotic stresses, but their relative responses and their ecological plasticity for a given species remain unknown. In this study, we examined the responses

OBJECTIVE To optimize the extraction technology for polysaccharides from the root of Limonium sinense (Girard) Kuntze, Plumbaginaceae and evaluate the antioxidant capacity of polysaccharides from L. sinense (LSEP) MATERIALS AND METHODS: One-singer factor and response surface methodology(RSM) were

An antioxidant activity of the water-alcohol extracts of leaves of ten herbs from Western Siberia was studied. In vivo the capability of extracts to protect cells of Escherichia coli against the bacteriostatic action of H2O2 and the influence of the extracts on the expression of the antioxidant gene

Salinity causes oxidative stress in plants by enhancing production of reactive oxygen species, so that an efficient antioxidant system, of which ascorbic acid (AsA) is a key component, is an essential requirement of tolerance. However, antioxidant responses of plants to salinity vary considerably

This work reports the in vitro antioxidant and anti-inflammatory activities and toxicity of infusions and decoctions of Limonium algarvense flowers, and green tea. The total contents in different phenolic groups and the quantification of individual phenolics by HPLC are also reported. L. algarvense

Natural antioxidants are widely used as dietary supplements or food additives. An optimized method of ultrasound-assisted extraction (UAE) was proposed for the effective extraction of antioxidants from the flowers of Limonium sinuatum and evaluated by response surface methodology. In this study,

Limonium is a genus represented in the Iberian Peninsula by numerous halophytic species that are affected in nature by salinity, and often by prolonged drought episodes. Responses to water deficit have been studied in four Mediterranean Limonium species, previously investigated

A free radical scavenging activity guided fractionation of the polar extract from roots of Limonium brasiliense (Plumbaginaceae) led to the isolation of five active compounds including: myricetin 3-O-alpha-rhamnopyranoside (1), (-)-epigallocatechin 3-O-gallate (2), (-)-epigallocatechin (3),

A new phenolic compound, 6'-O-sulfonyl-salidroside (1), together with fifteen known compounds, were isolated from the all parts of Limonium pruinosum. Their structures were elucidated by 1D and 2D NMR experiments including 1D TOCSY, DQF-COSY, HSQC and HMBC spectroscopy, as well as ESIMS analysis.

Unbalanced differentiation of bone marrow cells into adipocytes rather than osteoblasts causes severe bone-related disorders, such as osteoporosis. Natural products that can act against unbalanced differentiation are targeted for development of functional dietary supplements. Limonium tetragonum, a

UNASSIGNED Limonium tetragonum, a naturally salt-tolerant halophyte, has been studied recently and is of much interest to researchers due to its potent antioxidant and hepatoprotective activities. UNASSIGNED In the present study, we attempted to elucidate bioactive compounds from ethyl acetate

The aim of this study was to determine whether the medicinal herbs growing in Okinawa and possessing a radical-scavenging activity would exert cardioprotective effects against ischemia-reperfusion injury using isolated perfused rat hearts. Effects of the aqueous extracts from Psidium guajava L. and

Environmental conditions during the in vitro stages of a micropropagation process can further affect the ex vitro plant performance. In this work, the behaviour of four blue cultivars of statice (Limonium sinuatum) was studied with respect to four distances (18.0, 12.5, 8.0, or 2.0 cm) between

Rhododendron tomentosum Harmaja (previously: Ledum palustre) is a fragrant evergreen shrub found in peaty soils in northern Europe, Asia and North America, commonly referred to as wild rosemary, marsh tea, marsh rosemary or northern Labrador tea. At least since the eighteenth century it has been
