Methanolic extracts of 11 Rumex L. species (Polygonaceae) were examined against brine shrimp and R. scutatus L. has shown significant brine shrimp lethality (LC5O=0.96 |a,g/ml). Methanolic extracts of the roots of R. scutatus were fractionated and the active fraction led to the isolation of 4 anthraquinone aglycones: emodin, chrysophanol, physcion and aloe emodin. Their toxic sequence was found...

The electrical conductivity of brine-bearing quartzite with fluid fractions of 0.19 to 0.30 and salinity of 3 to 17 wt.% was measured at 800 to 1,100 K and 1 GPa. The conductivity of the brine-bearing quartzite increases with salinity and fluid fraction, but is almost independent of temperature. Our results suggest that regions of high conductivity (10 to 10 S/m) in the crust could be explained...

In vitro studies were carried out to evaluate the cytotoxic potential of the ethanolic and aqueous extracts of Luffa acutangula against human neuronal glioblastoma cells (U343) and human lung cancer cells (A549). Screening of these extracts was done using the brine shrimp lethality bioassay, MTT assay and SRB assay. The results showed the significant decrease of the viability of the cells in a ...

process for tlic separation of silica Amiata reinjection geothermal scaling causes serious problems in operation and maintenance of reinjection facilities, is reported, in which the phases of coagulation, and of silica are involved Brines discharged from three wells were studied, in order to investigate the influence of the brine composition on of tlie separation treatment. The addition of amou...

Background and Objectives: Red beet juice, a potential source of valuable nutrients, is widely used as a colorant in food industries. In recent years, to avoid reduction of nutritional values of the red beet during concentration by thermal processing, an osmotic distillation (OD) technique has been suggested. Therefore, the major aim of the present study was to investigate effects of the flow r...

Moringa oleifera leaves are recognized as nutritionally and medicinally important for life. Maintaining the freshness of is a challenge due to their very low shelf The aim this study examine effect nutritional quality by cost-effective preservation methods. 
 Samples raw, sundried, oven-dried, brine-preserved were investigated % proximate compositions based on AOAC antioxidant potential wa...
