Ultrasound has been regarded as an efficient novel technique for debitterizing of the apricot kernels, but its influence is severely concerned on the possible epimerization of D-amygdalin to the L-amygdalin, a more potentially toxigenic compound. Consider

An efficient procedure for the synthesis of cyanogenic glycosides with different carbohydrate units was developed. Amygdalin (3), prunasin (1), sambunigrin (2), and neoamygdalin (21) were prepared according to the elaborated method, and biological tests, including antifungal, antibacterial, and cytotoxic activities, were performed.

Chemical investigation of the seeds of Prunus davidiana afforded seven new aromatic glucosides, i.e., the prupersins A-E (1-5) and compounds 6 and 7, as well as 11 known compounds. The structures of 1-7 were elucidated by spectroscopic data analysis and chemical evidence, and configurations were determined by hydrolysis experiments (1, 2, and 5) or electronic circular dichroism (6). Compounds 1-6 exhibited antioxidant activity aganist Fe 2+-cysteine-induced rat liver microsomal lipid peroxidation, with malondialdehyde inhibitory rates of 50-67% and 53-57% at concentrations of 10-5 and 10-6 mol/L, respectively.
Phenylalanine derived cyanogenic diglucosides from Eucalyptus camphora and their abundances in relation to ontogeny and tissue type

experimental part, p. 2325 - 2334 (2012/01/31)
The cyanogenic glucoside profile of Eucalyptus camphora was investigated in the course of plant ontogeny. In addition to amygdalin, three phenylalanine-derived cyanogenic diglucosides characterized by unique linkage positions between the two glucose moiet
Study on the Prevention of Racemization of Amygdalin
Takayama, Yuzi,Kawai, Satoshi
, p. 778 - 781 (2007/10/02)
Studies were conducted to find suitable conditions for the prevention of racemization of amygdalin in aqueous solution.Evaluation of racemization was carried out by determination of the ratios of neoamygdalyn and amygdalin using a capillary gas chromatographic technique.Racemization of amygdalin in aqueous solution was accelerated by increases on pH and temperature, but racemization was low below pH 3.0 even with heating.Ascorbic acid is useful as an acidification reagent for the suppression of racemization, and has the added clinical benefit of vitamin C activity.Keywords - amygdalin; isoamygdalin separation; racemization; racemizati on prevention; capillary gas chromatography
