Interference ofPisum sativum L. root and leaf extracts with nitrite determination

Crude extracts ofPisum sativum L. roots interfere with nitrite determination only slightly, boiled root extracts considerably, Crude leaf extracts can interfere with nitrite determination in some cases even more than boiled root extracts. The precipitate of zinc phosphate helps to remove from crude leaf extracts some but not all the interfering material. Heating does not increase the interference in adult leaf extracts but it increases it in the extracts of very youngPisutn sativum leaves.
