CAS Registry Number: 8001-08-9
Literature References: An extract from the dried fruit of the Norway maple Acer plantanoides L., Aceraceae. Freshly prepd solutions of acerin destroy E. coli and vaccinia virus in 5 min but are less effective on the Staphylococcus Twort virus. Phagicidal action also exists even in the presence of the host cells. Extraction and properties: G. Fischer, Acta Pathol. Microbiol. Scand. 31, 433 (1952); 34, 482 (1954); Fischer et al., Experientia 10, 329 (1954).
Properties: Practically insol in methanol, ethanol, ether, acetone. Does not dialyze through a cellophane membrane at room temp but passes through a Seitz filter. Sodium chloride precipitates the active principle in acerin preparations as does also normal serum with 1:800 solns of acerin. Strong acerin preparations acquire reddish-brown color after treatment with alkali and oxidation in air. In general, the substance behaves similarly to vegetable tannins.
