DETERMINATION OF THIAMINE HYDROCHLORIDE AND PYRIDOXINE HYDROCHLORIDE ON RICE WITH WASHING, MILLING AND POUNDING BY SPECTROMETRIC METHODS

Simultaneous Determination of Doxylamine Succinate, Pyridoxine Hydrochloride and Folic Acid by Chemometric Spectrophotometry

Simultaneous estimation of three component tablets containing Doxylamine succinate (DOX), Pyridoxine hydrochloride (PYR) and Folic acid (FA) was carried out by UV spectrophotometric assisted chemometric methods. Four chemometric methods i.e. classical least square (CLS), inverse least square (ILS), principal component regression (PCR) and partial least squares (PLS) were applied to simultaneous...

A Toxicity Study of Thiamine Hydrochloride.

Observations on the mechanism of thiamine hydrochloride absorption in man.

1. The intestinal absorption of [35S]thiamine hydrochloride was investigated in healthy subjects, malnourished alcoholics and a patient with resection of the jejunum and ileum. Serum and urinary radioactivity was studied after administration of 10 pCi of [35S]thiamine hydrochloride in 1-50 mg of non-radioactive thiamine hydrochloride. 2. Results suggest that intestinal absorption of thiamine hy...

on the comparison of keyword and semantic-context methods of learning new vocabulary meaning

the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...

Normal and reverse flow injection–spectrophotometric determination of thiamine hydrochloride in pharmaceutical preparations using diazotized metoclopramide

Simple and sensitive normal and reverse flow injection methods for spectrophotometric determination of thiamine hydrochloride (THC) at the microgram level were proposed and optimized. Both methods are based on the reaction between THC and diazotized metoclopramide in alkaline medium. Beer's law was obeyed over the range of 10-300 and 2-90 μg/mL, the limits of detection were 2.118 and 0.839 μg/m...
