Objectives: The present study was to study the phytochemical and antibacterial properties of Alternanthera brasiliana leaf extracts using three different solvents (hexane, chloroform and methanol) against human pathogenic microorganism. Methods: Preliminary phytochemical screening of leaf extracts (in different solvents) of A. brasiliana were qualitatively tested using standard procedures. Thin...

Introduction: To establish the pharmacognostical and phytochemical standardization parameters of Pyrus pashia fruits in order to ensure quality and safety of this traditionally acclaimed medicinal tree. Methods: The fresh fruits of P. pashia were collected and dried. Fruit was subjected to various pharmacognostical investigations, Extraction procedures, and preliminary phytochemical screening, ...

Bauer alkylamide 11 and Bauer ketone 23 were previously found to be partially responsible for Echinacea angustifolia anti-inflammatory properties. This study further tested their importance using the inhibition of prostaglandin E(2) (PGE(2)) and nitric oxide (NO) production by RAW264.7 mouse macrophages in the absence and presence of lipopolysaccharide (LPS) and E. angustifolia extracts, phytoc...

The present study was designed to evaluate the Phytochemical composition, antioxidant activity and antimicrobial activity of Lagestroemia parviflora collected from Melghat Forest near Madki Village, TalChikhaldara, DistAmravati (M.S) Central region of India. Phytochemical screening was carried out by ‘guide to modern techniques of plant analysis”. Furthermore antioxidant activity of methanolic ...

India being a rich and varied flora of medicinal plants since the Vedic period. The present study deals with the phytochemical screening and thin layer chromatographic studies of Aerva lanata root extract belonging to family Amaranthaceae. Phytochemical screening determination by some chemical tests and thin layer chromatographic study was carried out by using various solvent system of varying ...

DNA fingerprinting singly or in combination with phytochemical analysis is ideal for quality control of crude plant-based drugs. However, when the source material is tannin rich stem bark, extraction of DNA by conventional methods becomes challenging. In such cases, phytochemical profiling serves as very useful tool for its identification. The work herein described a method for simultaneous DNA...

methanol 70% extract of bauhinia racemosa aerial parts was tested for antimicrobial activity against different bacterial and fungal strains and for antioxidant activity and also total content of polyphenols with phytochemical analysis of the extract was determined. the results have showed that the extract has a significant antimicrobial activity, it inhibited the growth of bacillus subtilis and...

Phytochemical studies have experienced a great deal of change during the last century, not only regarding the number of compounds described, but also in the concept of phytochemistry itself. This change has mainly been related to two key points: the methodologies used in phytochemical studies and the questions regarding 'why secondary metabolites appeared in plants and in other living organisms...

The synergistic effect of three phytochemicals, nonacosan-10-ol, 23a-homostigmast-5-en-3β-ol and cisand transprotopinium were assessed in four combinations and three concentrations (5, 50 and 100 μg ml-1) against Meloidogyne incognita, in vitro and in planta on the tomato cultivar Riogrande. Additionally, an in vitro phytotoxicity test on tomato seedlings was performed with the same phytochemic...
