Acid soluble and acid insoluble inorganic polyphosphates in Cuscuta reflexa

Abstract Inorganic polyphosphates have been isolated in both the “soluble” and “sinsoluble” form from the fresh stem tissue of Cuscuta reflexa (Dodder). Together they constitute about 2 per cent of the total phosphate. The presence of phytin calls for special precautions in the identification and estimation of soluble polyphosphates in the cold trichloroacetic acid extracts.
