Fig. 6. Three-dimensional chromatographic display of photodiode array data obtained
from MS-HPLC of P. papatasi and P. duboscqi salivary gland
homogenate (SGH). The three-dimensional data show retention time on the
x-axis, UV absorbance on the y-axis (in milli absorbance
units) and the UV absorbance spectra on the z-axis (from 200 nm to
320 nm). Adenosine and AMP standards show retention times of 18.5 and 14.5
min, respectively.
