Pollens release enzymes when they are dropped into water. Orchard Grass extracts were tested by two methods. The Api-Zym System determined 19 enzymes and colorimetric amounts of Leucine Aminopeptidases, Acid phosphatase and trypsin. These were compared with RAST inhibition assays. A good correlation was shown between the techniques. Thus the enzyme dosage may be useful for the standardization of pollen extracts.
