Background: Padina sp. is an algae that has potential as a functional food. This study aimed to explore the chemical and photochemical constituent in the methanolic exract of Padina sp. Methods: Brown algae of Padina sp. from Puntondo coast, Takalar, Indonesia was prepared. The algae characterization was carried out based on the standard procedure of Association of Official Agricultural Chemis...

In the present study, 32 hexane and ethanol extracts of Protium bahianum, P. heptaphyllum, Croton sellowii, C. rhamnifolius, C. jacobinensis, C. micans and Muntingia calabura were screened for antibacterial activity by the disc-diffusion method. Cytotoxicity assays using the brine shrimp Artemia salina Leach as a model were performed to determine lethal doses for 50% of individuals (LC50 μg/mL)...

background and objectives: phlomis olivieri benth. (lamiaceae) is a medicinal plant widely distributed in iran. in the present study, we have investigated the phytochemical constituents, antioxidant activity and general toxicity potential of the aerial parts of this species. methods: silica gel (normal and reversed phases) and sephadex lh-20 column chromatographies were used for isolation of co...

Objective: Phytochemical screening as well as several bioassays was performed on the extracts of aerial parts of Caragana jubata. Methods: Extraction of C. jubata was carried out by solvents of increasing polarity. The Phytochemical screening of extracts was carried out using standard procedures. Furthermore, extracts were also evaluated for (i) antibacterial assay, (ii) brine shrimp lethality ...

ARTEMIA is commonly known as the brine shrimp. It is a crustacean. It lives high saline waters. It is widely distributed throughout the world; it is the most important live feed organism. ARTEMIA lives in high saline environment where its predators cannot survive. Hence ARTEMIA can be effectively cultured in saline water. Such water bodies are found in solar saltpans, which occur all along Indi...

Isolated five known iridoids glycosides (Scrophuloside A, Harpagoside B, 5-hydroxyloganin, 8-O-acetylharpagide and 6-O-methyl,1-glucopyranosyl catalpol ),one phenyl ethanoid glycoside (Verbascoside) and a phenyl ethanol amine (2-(4-Chlorobenzyl amino) ethanol ) compound from the methanolic extract of aerial parts of Scrophularia oxysepala using by high performance liquid chromatography based on...

Copepods and brine shrimp, which represent different species of zooplankton with similar inertial time constant, can behave very differently when subjected to velocity gradients in unsteady or turbulent flows. Upon sensing hydrodynamic disturbances, copepods can respond with rapid acceleration and high speed. Brine shrimp, on the other hand are more passive and capable of only small relative sw...
