Cyanogenic glycoside, amygdalin (AM) and its degradation products, benzoic acid (BA) and benzaldehyde (BAL) in rose family plants were measured utilizing high performance liquid chromatography (HPLC). Liqueur was cleaned in an InertSep NH2 cartridge, and other samples were cleaned in an InertSep C18 cartridge and an InertSep NH2 cartridge. The three components were not detected in any sarcocarp. AM was detected in seeds of loquat, apricot and cherry in the range of 1.35〜28.80 mg/g, and BAL was detected at 0.48 mg/g in seeds of apricot. AM and BA were detected at 0.83 mg/g and 0.10 mg/g in tea processed from loquat seed.
