6 7 8 9 Abstract 10 Cyanogenic glycosides are natural plant toxicants. Action by endogenous plant enzymes 11 can release hydrogen cyanide causing potential toxicity issues for animals including 12 humans. We have quantified amygdalin in seeds from different apple varieties, determined 13 the effects of processing on the amygdalin content of apple juice and quantified amygdalin 14 in commerciall...
Information about the natural compound amygdalin, which is employed as an antitumor agent, is sparse and thus its efficacy remains controversial. In this study, to determine whether amygdalin exerts antitumor effects on renal cell carcinoma (RCC) cells, its impact on RCC metastatic activity was investigated. The RCC cell lines, Caki-1, KTC-26 and A498, were exposed to amygdalin from apricot ker...
Background and Objective: Amygdalin is likely to have analgesic and metabolic effects. In this study, the effects of chronic administration of amygdalin were investigated on the pain threshold, weight and blood sugar of mice. Materials and Methods: In this experimental study, formalin test was used as a chronic inflammatory model of pain. 60 mice (30-35 g) were divided into four groups (n=15) i...
Amygdalin is widely distributed in loquat plant which belongs to Rosaceae and used as an important pharmaceutical compound. In this research, High Performance Liquid Chromatography (HPLC) was used to determine the content of amygdalin in different tissues of loquat fruit cv. ‘Dahongpao’, as well as leaves, roots and flowers. The results demonstrated that the kernel had the highest content of am...
Background and Aim: There are many controversial reports about the toxic effects of Amygdalin as an anticancer drug. The aim of the present study was to investigate the histological effects of Amygdalin on the mouse liver. Materials and Methods: Thirty two adult male mice were selected and divided into 4 equal groups control, 10 mg/kg Amygdalin group, 25 mg/kg Amygdalin group, and 50 mg/kg Amyg...
Amygdalin, the gentiobioside derivative of mandelonitrile commonly referred to as Laetrile, is presently under intensive investigation as a potential cancer chemotherapeutic agent. Because of this interest, we investigated the activity of beta-glucosidases that cleave glucose from amygdalin and from prunasin (mandelonitrile monoglucoside) in tissues from germ-free rats and in normal and neoplas...
Amygdalin is a cyanogenic diglucoside and constitutes the bitter component in bitter almond (Prunus dulcis). Amygdalin concentration increases in the course of fruit formation. The monoglucoside prunasin is the precursor of amygdalin. Prunasin may be degraded to hydrogen cyanide, glucose, and benzaldehyde by the action of the β-glucosidase prunasin hydrolase (PH) and mandelonitirile lyase or be...
Amygdalin is a cyanogenic glucoside found in apricot kernels. To facilitate the exploitation and use of wild apricot resources, it is necessary to be able to rapidly and efficiently determine the amygdalin levels within their kernels. To do so, this paper compares two methods, one based on second-derivative UV spectrophotometry and the other on highperformance reversed-phase liquid chromatograp...
Cyanogenic glycosides are a large group of secondary metabolites that are widely distributed in the plant kingdom, including many plants that are commonly consumed by humans. The diverse chemical nature of cyanogenic glycosides means that extraction and analysis of individual compounds can be difficult. In addition, degradation can be rapid under appropriate conditions. Amygdalin is one of the ...
Significant amounts of cyanide are released when amygdalin (Laetrile), a cyanogenic glycoside, is given orally or intravenously to rats. The amount of cyanide liberated following oral administration is dependent in part on the bacterial flora of the gut and can be suppressed by antibiotic pretreatment of the animals. Bacteria from human feces likewise hydrolyze amygdalin with release of cyanide...
