A simple and rapid method has been developed for the quantification of Domperidone (DMP) and Paracetamol (PAR) through FT-IR in combined dosage form. The method involves the measurements of peaks of carbonyl group (C=O) at 1656 cm (PAR) and 1717 cm (DMP). An UV-Spectrophotometric method was also described for the simultaneous determination of DMP and PAR. The analytical results obtained with FT...

The application of single-pass attenuated total reflection Fourier transform infrared (ATR-FT-IR) microscopy was investigated for secondary structure analysis of 15 representative proteins in H2O solution. This is the first reported application of single-pass ATR-FT-IR for protein analysis; thus, the method was validated using transmission FT-IR and multipass ATR-FT-IR as referee methods. The s...

background: ß-carbolines, harmaline and harmine, are the major alkaloids presenting in the seeds of the peganum harmala l. these alkaloids are known as herbal active principals with potential use in pharmaceutical and medicine. objectives: to assess the growth inhibitory effect of phyto-alkaloids, harmaline and harmine, on cancer cell lines. methods: the p. harmala l.’s alkaloids were extracted...

parthenolide is major sesquiterpene lactones present in anthemis haussknechtii boiss. & reut. (feverfew). this compound has many effects on different disease such as migrain and cancer. parthenolide was reported from tanacetum parthenium (l.) sch.bip. but other plants of asteraceae family could contain parthenolide. in this study parthenolide was extracted and identified with two methods, fouri...

2-(5,6-diphenyl-1,2,4-triazin-3-yl)pyridinium dichloroiodate (I) (1) was synthesized by reacting 3-(2-pyridyl)-5,6-diphenyl-1,2,4-triazine with ICl in dichloromethane solution. The structural characterization of 1 SC-XRD analysis accompanied elemental analysis, FT-IR, and FT-Raman spectroscopy measurements.

Low Carbohydrate High Protein (LCHP) diet displays pro-atherogenic effects, however, the exact mechanisms involved are still unclear. Here, with the use of vibrational imaging, such as Fourier transform infrared (FT-IR) and Raman (RS) spectroscopies, we characterize biochemical content of plaques in Brachiocephalic Arteries (BCA) from ApoE/LDLR(-/-) mice fed LCHP diet as compared to control, re...

A new concept of designing and synthesizing highly dispersed ionic liquids was developed through physical confinement or encapsulation of them into silica gel matrix with sol-gel process. A series of silica gel confined ionic liquids were synthesized through this process and characterized by diffuse-reflectance infrared Fourier transform spectroscopy (DRIFTS) and FTRaman analysis, and abnormal ...
