Total flavonoids contents and antibacterial activity of the extracts from the aerial parts of two Labiateae species, Nepeta menthoides Boiss. & Buhse and Thymus trautvetteri Klokov & Desj.-Shost. were determined. Quantitative determination of flavonoid contents was calculated in terms of quercetin equivalent in various extracts (50% methanol, chloroform and distilled water) by AlCl3 colorimetri...

High-performance liquid chromatography (HPLC) fingerprinting is a reliable quality control method for traditional Chinese medicine (TCM). As research combining fingerprint and pharmacodynamics of TCM, the TCM spectral effect relationship widely used in its preparations, which can better reflect intrinsic great significance on material basis efficacy. In this study, an HPLC extracts from aerial ...

background and objectives: the main aims of this study have been finding out the antibacterial activity and preliminary phytochemical screening of some fern species. methods: the antimicrobial activity of the methanol extracts of polypodium interjectum shivas, polystichum woronowii fomin, polystichum aculeatum (l.) roth., dryopteris affinis (lowe) fraser-jenk, athyrium filix-femina (l.) roth, a...

background and objectives: many nepeta species have been commonly used in iranian folk medicine as tranquilizer, relaxant, carminative and restorative tonic for nervous and respiratory disorders. inflammation is a problem in many diseases and has an important role in brain function that can cause neurodegenerative disorders. inflamed glial cells can exacerbate neurodegenerative diseases by prod...

in the present study, we have reported the total phenolic content, total flavonoid content, antioxidant and antimicrobial activity of aerial parts of salvia leriifolia extracts and fractions. methanolic, n-hexane, chloroform, and ethyl acetate extracts were screened to analysis their antioxidant activities by four complementary test systems, namely dpph free radical scavenging activity (rsa), t...

Neuroprotective effect of the extract from aerial parts of Scrophularia striata Boiss (Scrophulariaceae) was investigated against glutamate-induced neurotoxicity on cultured rat pups Cerebellar Granule Neurons (CGNs). CGNs from 8 days old Sprague-Dawley rat were prepared and cultured. The experiments were performed after 8 days in culture. The plant was collected from the northeastern part (Rui...

The aim of the present work is the evaluation of anti cancer effect of Carica papaya aerial parts extracts and also the investigation of the phytoconstituents from the extracts of the plant. Petroleum ether (40-60C), Chloroform, ethyl acetate and methanol 80% extracts of C. papaya aerial parts were tested for their anti cancer activity on three cancer cells TK10 (renal), UACC62 (melanoma) and M...

This study was undertaken to determine the antioxidant and antimicrobial effect of essential oil and extracts of Echinophora sibthorpiana Guss. (fam. Apiaceae) collected in Macedonia. The chemical composition of E. sibthorpiana essential oil was characterized by the presence of methyl eugenol (60.40%), p-cymene (11.18%) and α-phellandrene (10.23%). The free radical scavenging activity of extrac...

background and objectives:lallemantia iberica (lamiaceae) is a medicinal plant distributed in different parts of iran. this research, has evaluated the phytochemical constituents and antioxidant activity of the aerial parts of the plant. methods: different chromatographic methods such as column chromatographies using silica gel (normal and reversed phases), sephadex lh-20 and hplc were used for...

The extraction of road networks from aerial images is one of the current challenges in digital photogrammetry and computer vision. In this paper, we present our system for 3D road network reconstruction from aerial images using knowledge-based image analysis. In contrast to other approaches, the developed system integrates processing of color image data and information from digital spatial data...
