Prulaurasin content of leaves, kernels and pulps of Prunus lauracerasus L. (Cherry Laurel) during ripening

Abstract

Cyanogenic glycosides are highly toxic compounds distributed over 2500 taxa as secondary metabolites which release cyanide and benzaldehyde when degraded by endogenous enzymes. In this study, prulaurasin-a cyanogenic glycoside-content of Prunus lauracerasus L. (cherry laurel) leaves, kernels and pulps were investigated during the ripening period with a high-performance liquid chromatographic (HPLC) method. In leaves, prulaurasin pursues a relatively linear path while in kernels, it rapidly increases during fruit development. The higher amount of prulaurasin was quantified in the early stages of pulps and decreased over time to an undetectable level in mature form to form an edible fruit that promotes propagation.

Changes of Endophytic Bacterial Community in Mature Leaves of Prunus laurocerasus L. during the Seasonal Transition from Winter Dormancy to Vegetative Growth

“…It belongs to one of the most important hardy nursery stock species. A high concentration (1% to 2.5%) of medicinally important α-hydroxymandelonitrile derivatives of cyanogenic glycosides was found in cherry laurel leaves, fruits, and seeds such as prunasin, sambunigrin, and amygdalin [ 37 ], which possess pharmacological activities [ 38 ]. Cherry laurel fruits are used in traditional medicine for stomach ulcers, digestive system complaints, bronchitis, eczemas, haemorrhoids, and as diuretic, antipyretic, and as analgesic agents [ 39 ].…”

“…4.9 GLICÓSIDOS CIANOGÉNICOS Son compuestos nitrogenados no tóxicos, pero se degradan cuando la planta es aplastada liberando sustancias volátiles tóxicas como HCN. Se identifican mediante la reacción de Guignard, donde se adiciona CHCl 3 produciendo una hidrólisis enzimática con liberación de HCN, este reacciona con el picrato de sodio reduciéndolo a isopurpurato de coloración rojiza (-) (Demirbolat & Kartal, 2019;Gurgur et al, 2020).…”
