- Title
PORPHYRINS WITH FORMYL GROUPS VII.
- Authors
Lemberg, R.; Parker, J.
- Abstract
Using the specific extinction values of porphyrin α, protoporphyrin and cryptoporphyrin α at four chosen wavelengths, spectrophotometric methods of analysis are worked out which allow the estimation of these porphyrins in mixtures of two or three of them. The yields of cryptoporphyrin α from heart muscle, determined by one of these methods, varies with the procedure. With the methods developed by Lemberg, Bloomfield, Caiger and Lockwood (1955), it is little more than one-twentieth that of porphyrin α. Cryptoporphyrin a is probably an artifact derived from porphyrin α.
