    Probable Identity of the Pectinase Inhibitor in Grape Leaves (1961)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 26 (1961), S. 0

    Notes: Studies were continued on the chemical nature of the water-soluble substance in Muscadine grape leaves that was previously reported as inhibiting pectinase and cellulase. The inhibitor is a tannin or tannin-like material, removable from leaf extracts by hide powder, caffeine, gelatin, and nicotine sulfate. Muscadine leaves had the highest inhibiting activity of the plants tested.

    Isolation and Description of the Pectinase-Inhibiting Tannins of Grape Leaves (1962)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 27 (1962), S. 0

    Notes: Studies were continued on the tannin in Muscadine grape leaves previously reported to have inhibitory activity toward peetinase and cellnlase. The tannin was isolated and purified by precipitation with caffeine and recovery by chloroform extraction. The material is a light tan, and in the freeze-dried form is quite bulky. It is a condensed tannin of high molecular weight, producing a large percentage of phlobaphenes upon acid treatment. The soluble portion after acid treatment was shown to contain gallic acid and glucose in small amounts.
