The present investigation of crude extracts from the whole plant Merremia umbellata was done by cold maceration with methanol and pet ether solvent subjected to preliminary phytochemical, pharmacological screening, antibacterial against selected Gram-positive Gram-negative bacteria. Phytochemical studies indicate presence Flavonoids steroids, alkaloids, carbohydrates, Triterpenoids glycosides, ...

Resumen Context: There is a wide variety of methods for obtaining of plant extracts that enable a good yield of bioactive metabolites. For several years, extractive techniques have been perfected for obtaining natural extracts with powerful pharmacological properties. Aims: To determine the influence of various extraction methods (infusion, decoction, microwave, maceration with heat and agitati...

The necrotrophic bacteria Dickeya dadantii is the causal agent of soft-rot disease in a broad range of hosts. The model plant Nicotiana benthamiana, commonly used as experimental host for a very broad range of plant pathogens, is susceptible to infection by D. dadantii. The inoculation with D. dadantii at high dose seems to overcome the plant defense capacity, inducing maceration and death of t...

The results of studies by Jandera and Arturson suggest that the cooling effect in the treatment of burns, well known as an emergency therapeutic measure, should not be seen merely as cooling but also as a form of topical hydration of the lesion, apart from its systemic effect. Excess hydration produces maceration of the skin, which can lead to greater exposure to infection in the burn zone. In ...

The current research focuses on the estimation of bulk density and angle of repose of tea leaves at different moisture content and size and development of a mathematical model for bulk density and angle of repose using response surface methodology followed by numerical optimization of responses using desirability functions. Further work was done on the design optimization of feed hopper and met...

The three-dimensional architecture of filamentous components in the lamina densa of the Schwann cell basement membrane was studied in the mouse sciatic nerve by transmission and scanning electron microscopy after osmium-maceration treatment, and also by conventional electron microscopy. In conventionally prepared specimens, the lamina densa of the basement membrane was the most electron-dense, ...

Objective: The present study was aimed to assess the anti-inflammatory activity profile of Barleria spp. viz., B. prionitis Linn. and B. cristata Linn. against different models of inflammation in female rats. Methods: Seven different extracts viz., mother extract (methanolic, ME, maceration), hexane (HE), chloroform (CE), ethyl acetate (EAE), butanol (BE) and left aqueous (LAE) extract obtained...

Pistacia vera L., a member of Anacardiaceae family, has been used for sedation and analgesia in traditional medicine. In this study, the antinociceptive and anti-inflammatory effects as well as acute toxicity of the aqueous and ethanolic extracts of P. vera leaves were investigated in mice. The antinociceptive activity was studied using hot plate and writhing tests. The effect of the extracts a...
