Magnetite (Fe₃O₄) is a ferromagnetic iron oxide of both Fe(II) and Fe(III), prepared by FeCl₂ and FeCl₃. XRD was used for the confirmation of Fe₃O₄. Via the modification of Tetraethyl orthosilicate (TEOS), (3-Aminopropyl)trimethoxysilane (APTMS), and Alginate (AA), Fe₃O₄@SiO₂, Fe₃O₄@SiO₂-NH₂, and Fe₃O₄@SiO₂-NH₂-AA nanoparticles could be obtained, and IR and SEM were used for the characterizatio...
Two major bisbenzylisoquinoline alkaloids, isotetrandrine and berbamine and three protoberberine type alkaloids berberine, palmatine, and jatrorrhizine were isolated from seeds of Berberis thunbergii DC. Berberine and oxyberberine, which is not present in the seeds, were isolated from the pericarp. Identity of the isolated substances was verified by spectral means (i.r., u.V., and mass spectrom...
Helicobacter pylori (H. pylori) is the most important factor of gastric disease in clinical practice. Moreover, smoking, stress and a poor diet may be additive factors for gastric damage. With these factors, increasing infection of H. pylori triggers gastritis, gastric ulcers and gastric cancer. To develop a new protective agent, we are concerned with plant-derived extract. The extract of Copti...
Five alkaloids were isolated from the underground part of Mahonia aquifolium of domestic origin: magnoflorine, berberine, palmatine, jatrorrhizine, and columbamine. The aerial part of this plant contained only berberine, palmati ne, and jatrorrhizine. The identity of the isolated bases was corroborated by colour reactions in the u.v. light, by i.r. and mass spectra, optical rotation and compar...
Abstract Acute myocardial infarction is one of the major leading causes for heart failure, which can lead to irreversible loss cardiomyocytes and impaired cardiac function. Hence, efficient therapeutic agents are still urgent. Our study aimed explore role a natural isoquinoline alkaloid, palmatine, in an acute mouse model. In this study, intragastric administrated palmatine significantly enhanc...
A selective and sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed for the determination of berberine, palmatine and jatrorrhizine in rat plasma. Target compounds, together with the internal standard (metronidazole), were extracted from rat plasma samples by protein precipitation with acetonitrile-methanol (1:2, v/v). Chromatography was carried out using a ...
Background: Finding effective drugs is considered for healing diabetic wounds by researchers. The purpose of this study is to evaluate the wound healing effects of palmatine in the healing of skin wounds in normal and diabetic rats. Methods: In this study 16 male Wistar rats were dهvided into four groups (Negative control, Positive control, The first experimental,The second experimental) . ...
The dried park from Enantia chlorantha, was milled and solved into methanol overnight, separated the solute by decantation and repeat the previous process. The sediment was refused. The solute was concentrated and water was used to precipitate the proteins and they have discarded. After these procedures we have got at an alkaloid mixture, which according our GC/MS analysis had a palmatine basic...
