Quantitative Determination of Azadirachtin in Melia indica and M. azedarach

Background: Melia indica and M. azedarach (Meliaceae) are widely used in traditional medicine. These species are considered as natural pesticides. Their major compound is azadirachtin (AZD) which is considered as the marker for quality control of these species. Objective: In the present investigation, AZD content of the leaves and fruits (comprising the whole fruit, peel, pulp and seeds) of M....

Qualitative and Quantitative Approaches for Determination of Hemolyzed Serum

Abstract Background and Objective: Prevention of medical laboratory errors is a major goal of quality control programs. Hemolyzed specimen is one of the common issues causing medical laboratory errors. Apart from the visual assessment, the measurement of serum hemoglobin concentration can be another method to evaluate the intensity of hemolysis. We aimed to assess hemolyzed serum s...

Quantitative colorimetric determination of tryptophan.

The methods currently used for the estimation of tryptophan are based on one of the following principles: Reaction with aldehydes in acid solution (1, Z), with glyoxylic acid (3), with mercury salts and nitrous acid (4,5), by determination after isolation from its mercury salt (6)) or by the use of Marshal’s reagent (7). Of the above mentioned methods, those based on aldehyde reactions and on t...

Quantitative determination of collagen crosslinks.

The primary functional role of collagen is as a supporting tissue and it is now established that the aggregated forms of the collagen monomers are stabilised to provide mechanical strength by a series of intermolecular cross-links. In order to understand the mechanical properties of collagen, it is necessary to identify and quantitatively determine the concentration of the cross-links during th...
