From data, it is that only two these (ADHP-1 ADHP-12) complied safety limit (as stated Pharmacopoeias WHO guidelines) evaluated by all counts....

It is evident that date fruits provide a wide variety of essential nutrients which impart potential human health benefits. In Bangladesh, the popularity and its consumption surge few-fold during Ramadan among Muslims owing to profound emotion related religious belief breaking dawn-to-dusk fasting with dates fulfilling Sunnah. The present study aimed explore microbiological quality five most popular fresh samples (Nagal, Dhapas, Boroi, Morium, Tunisia) purchased from different locations Dhaka...

Introduction. Along with and in competition orthodox medicines, herbal medicines have converted into a popular form of cure. While cumulative investigation reports on adverse effects by drug uptake are few, systematic review along deep insight other relevant topics (carcinogenic noncarcinogenic risk assessment, mechanism toxicity, entering toxic metal from source to drug) is sporadic. Methods. Therefore, existing research their published outputs pointing safety assessment terms metals been...

Salicylaldehyde semicarbazone ligand and its Cu (II) complex have been synthesized characterized by a range of physicochemical methods. Experimental data shows the is monomeric copper atom four coordinated in square planar geometry. The chelates tridentate fashion through carbonyl O, imine N, phenolato O with fourth position being occupied Cl. Antibacterial activity prepared compounds was tested against microbes Enterobacter Aerogenes Bacillus Cereus. metal showed higher antibacterial than...

Widespread escalation of type 2 diabetes is a concern throughout the world. Developing countries are leading with patients suffering from diabetes-related complications. Plant-based therapeutic, antidiabetic herbal preparations (ADHPs) being sought for long and consumption increasing in Bangladesh. do not go through screening procedure terms safety. Toxic metals ADHPs have been investigated by two different methods: atomic absorption spectroscopy (AAS) X-ray fluorescence (XRF). Then, metal...

Plant-based hypoglycemic therapeutics have been increasing in consumption due to the escalation of type 2 diabetes and its related complications. However, safety preparations is little understood. Parabens (alkyl esters p-hydroxybenzoic acid) are widely used as preservatives these pharmaceuticals. presence methylparaben formulations raises anxiety potential endocrine disruption functions. Endocrine could lead undesirable health abnormalities carcinogenic, estrogenic, adverse reproductive...

The objective of the study was to assess sodium benzoate and potassium sorbate in some anti-diabetic herbal drugs (ADHDs) collected from local markets using UV-Vis spectrophotometric method. Analytes were measured bulk finished drug formulations at 224 nm for Sodium 254.5 sorbate. calibration curve obeyed Beer’s law range 0-40 ppm 0-50 passed goodness fit evaluation. Limit detection, LOD limit quantification, LOQ 0.13 pm 0.40 respectively. quantification country is unknown. To conclude,...

Copper (II) complex of the ligand, thiophene-2-aldehyde semicarbazone was synthesized and characterized. Their structures were explored on basis CHN analysis, conductance magnetic susceptibility measurements, spectral studies (FT-infrared ESI-MS) thermogravimetric analysis (TGA). It has been observed from analytical studies, copper have composition [CuL(CH3COO)2(H2O)] [where L is semicarbazone]. The electrospray mass spectrum ligand exhibited ion at mass-to charge ratio (m/z) 169.13 368.86...

The metal (II) complexes, Na2[ML2] [M = Cu, Co, Ni, and Zn], of salicylaldehyde thiosemicarbazone (L) containing a trifunctional ONS-donor system have been synthesized characterized on the basis physicochemical data by elemental analysis, magnetic moment, molar conductance, spectroscopic (electronic, IR ESI-MS). ligand functions as ONS tridentates producing octahedral complexes. All compounds showed significant antibacterial activity in different ranges against gram positive (Bacillus...

In this study, jute polyethylene clay nanocomposites were developed using hot press technique. The hydrophilic nature of fiber and nanoclay exhibited poor interfacial interaction to hydrophobic polymer matrix. order enhance the among fiber, polymer, nanofillers, chemically treated (with benzenediazonium salt, propionic anhydride, 3-isocyanatopropyltriethoxy silane) organically modified used for manufacturing in study. effect chemical treatments addition on improvement absorption...

<title>Abstract</title> The present study investigates human health risks upon consumption of herbal medicines in terms ten toxic metals twenty plant-based anti-diabetic therapeutics. analysis was determined by an atomic absorption spectrometer after microwave-assisted digestion. computation hazard quotients (HQ) and indexes (HI) leads to the assessment non-carcinogenic risks.
