The absorbance of sample (methanolic extract of Nymphaea stellata and standard Butylated hydroxytoluene) were taken in triplicate.
In summary, use of photodegradation with a routinely available slide projector as the light source enables the absorbance attributable to bilirubin to be determined even in specimens containing high absorbances of the other pigments commonly seen in amniotic fluid contaminated with blood.
Relative allyl absorbances were determined directly after vulcanization of the compound and are presented in Fig.
As seen, the baseline absorbance reading for the sample from the index patient was markedly higher than the normal baseline reading, which is typically <0.
O-H, C-H) absorb light in this region, and it is well known that an analysis of NIR absorbance can be used to obtain information about the chemical structure of a sample (3).
The absorbance values of the controls (Control E, M, B and A) were significantly lower than the plant extracts.
For the Liley method, absorbance was measured at 365, 450, and 550 nm, and a baseline was estimated between 365 and 550 nm on a log-linear plot (with wavelength on the linear and absorbance on the log scale).
Comparison of the mean absorbances between sera of CD patients not on the GFD and non-CD controls showed significant differences (P = 0.
The recalculated absorbances for the individual pigments were then transformed to concentrations using calibration curves.
