The aim of the study was to investigate the Aloe vera phyto chemical compounds and antimicrobial activity of different extracts. The phytochemical compound screened by qualitative and GC-MS method. Qualitatively analyzed Tannin, Saponin, Flavonoids and Terpenoids gave positive results and phlobactanins and Steriods and Steriods gave negative results. In the GC-MS analysis, 26 bioactive phyteche...

in the present study, plumbago zeylanica linn. (plumbaginaceae) , one of the folk medicinal plants commonly used as antifertility agent was evaluated for its antifertility effect. five successive solvent extracts, petroleum ether, chloroform, acetone, ethanol and water extracts, of the stems of p. zeylanica were studied on estrous cycle at two dose levels, 200 and 400 mg/kg respectively.   of t...

In this study, we report a straightforward and reproducible hydrothermal synthesis of copper oxide nanowires, their morphological chemical characterization, application in gas sensing. Results show that the process is mainly influenced by reaction time concentration reducing agent, demonstrating fine long nanowires (diameter 50–200 nm length 25 µm) after 10 h with 0.1 M pyrrole. Two different a...

A wide range of parts of the medicinal plant is used for extract as raw drugs and they possess varied medicinal properties. The different parts are used include root, stem, flower, fruit, twigs exudates and modified plant organs. One of the greatest accomplishments of modern medicine has been the development of antimicrobials for the treatment of infectious diseases. Microbial diseases remain a...

The effects of extraction solvents (hexane, ethyl-acetate, acetone, ethanol, methanol, and water) on the content of phytochemicals including total polyphenols, flavonoids and condensed tannins, as well as antioxidant activities of walnut green husk were investigated. The results showed that extraction solvents significantly affected phytochemicals content and antioxidant activities of walnut gr...

The objective of this study was to optimize continuous acetone-butanol-ethanol (ABE) fermentation using a two stage chemostat system integrated with liquid-liquid extraction of solvents produced in the first stage. This minimized end product inhibition by butanol and subsequently enhanced glucose utilization and solvent production in continuous cultures of Clostridium acetobutylicum B 5313. Dur...

Citrullus colocynthis (Linn). Schred is an important medicinal plant of family Cucurbitaceae. The crude fruit extract were examined for antimicrobial potentialities against Gram positive, Gram negative bacteria and fungi. Fruit extract was evaluated on bacterial strains like Escherichia coli, Staphylococcus aureus, Salmonella typhi, Shigella shigella and Candida albicans .The solvent used for t...

In the present study deals with the antimicrobial properties of the Andrographis neesiana were tested against five human bacterial pathogens by using five various solvent namely, ethanol, methanol, acetone, chloroform and petroleum ether. The maximum antimicrobial activity was noted in petroleum ether extracts of stem showed activity against Escherichia coli (16mm) and the minimum was recorded ...

BACKGROUND High cost of traditional substrates and formation of by-products (such as acetone and ethanol) in acetone-butanol-ethanol (ABE) fermentation hindered the large-scale production of biobutanol. Here, we comprehensively characterized a newly isolated solventogenic and xylanolytic Clostridium species, which could produce butanol at a high ratio with elimination of ethanol and conversion ...

Antioxidant activity of Avicenni marina L and Avicennia officinalis L fruit extracts in ethyl acetate, acetone, methanol and ethanol were studied by ABTS, CrO5 and FRAP method. All the extracts possessed significant amount of the antioxidant activity, extracts in methanol and ethanol was demonstrated convincingly higher antioxidant activity by all the three methods. Whereas, the ethyl acetate e...
