New prenylated benzoic acid and other constituents from almond hulls (Prunus amygdalus Batsch).

One new prenylated benzoic acid derivative; 3-prenyl-4-O-beta-D-glucopyranosyloxy-4-hydroxylbenzoic acid; and three known constituents; catechin; protocatechuic acid; and ursolic acid; have been isolated from the hulls of almond (Prunus amygdalus). Complete assignments of the proton and carbon chemical shifts for the new prenylated benzoic acid derivative were accomplished on the basis of high-resolution 1D and 2D nuclear […]

Biochemical characterization of amandin; the major storage protein in almond (Prunus dulcis L.).

The almond major storage protein; amandin; was prepared by column chromatography (amandin-1); cryoprecipitation (amandin-2); and isoelectric precipitation (amandin-3) methods. Amandin is a legumin type protein characterized by a sedimentation value of 14S. Amandin is composed of two major types of polypeptides with estimated molecular weights of 42-46 and 20-22 kDa linked via disulfide bonds. Several […]
