this study aimed to determine biological activity and phytochemical study of scutellaria platystegia (family labiatae). methanolic (meoh) extract of aerial parts of s. platystegia and spe fractions of methanolic extract (specially 20% and 40% methanolic fractions), growing in east-azarbaijan province of iran were found to have radical scavenging activity by dpph (2, 2-diphenyl -1- pycryl hydraz...

BACKGROUND The concept of botanical therapeutics has revitalized due to wide importance of plant derived pharmaceuticals. Therefore, the ameliorative characteristics of Ajuga bracteosa were studied. METHODS Total phenolic content, flavonoid content, antioxidant capacity, reducing power and free-radical scavenging activity were determined colorimetrically. Specific polyphenols were quantified ...

Red betel (Piper crocatum) is a plant that often used as medicine. belongs to the Piperaceae family, grows vines with heart-shaped leaves and stems, which grow alternately from stem appearance of are silvery red shiny when exposed sunlight. contains flavonoid compounds, alkaloids, tannins, phenolic compounds essential oils. The results showed ethanol extract leaf active such flavonoids phenolic...

Great Salt Lake, Utah, is a large, terminal, hypersaline lake consisting of a northern more saline arm and a southern arm that is less saline. The southern arm supports a seasonally abundant fauna of low diversity consisting of brine shrimp (Artemia franciscana), 7 species of brine flies, and multiple species of algae. Although fish cannot survive in the main body of the lake, the lake is highl...

Purpose: To determine total phenolic and flavonoid contents, as well the cytotoxic, immunemodulatoryand anti-inflammatory potentials of whole plant Astragalus creticus (Fabaceae).Methods: Folin-Ciocalteu (FCR) method was used for determination contents methanol dichloromethane extracts creticus. The cytotoxic potential on 3T3 HeLa cell lines were evaluated using MTT assay. Brine shrimp larvae m...

Citrus grandis belongs to the Rutaceae family and is a naturally occurring citrus plant. The fractionated crude extracts of C. have been studied for investigation its phytochemicals allowed evaluation biological activities, especially antimicrobial, cytotoxic, antioxidant activities. At first, we assessed antibacterial antifungal properties using disc diffusion method conducted cytotoxicity scr...

Four new quinazolinone alkaloids, namely, aniquinazolines A-D (1-4), were isolated and identified from the culture of Aspergillus nidulans MA-143, an endophytic fungus obtained from the leaves of marine mangrove plant Rhizophora stylosa. The structures of the new compounds were elucidated by spectroscopic analysis, and their absolute configurations were determined on the basis of chiral HPLC an...

Bioassay-guided fractionation of a culture extract of Beauveria felina EN-135, an entomopathogenic fungus isolated from a marine bryozoan, led to the isolation of a new cyclodepsipeptide, iso-isariin D (1); two new O-containing heterocyclic compounds that we have named felinones A and B (2 and 3); and four known cyclodepsipeptides (4-7). The structures were elucidated via spectroscopic analysis...

INTRODUCTION In this study, we used dichloromethane (DCM) and methanol (MeOH) extracts of the Zingiber zerumbet rhizome to evaluate brine shrimp lethality and larvicidal activity on Aedes aegypti and Anopheles nuneztovari mosquitoes. METHODS Bioassays were performed by exposing third-instar larvae of each mosquito species to the DCM or MeOH extracts. RESULTS Probit analysis with DCM and MeO...
