An HPLC method was developed for the determination of @entity50252 (NHDC) in foods. A solid sample was extracted with @entity1042 . The extract was evaporated and the residue was dissolved in @entity1042 -water (2:8) mixture. In the case of fluid sample, the sample solution was prepared by dilution with @entity1042 -water (2:8) mixture. The sample solution was cleaned up on a C18 cartridge. The cartridge was washed with water and @entity1042 -water (3:7) mixture, and NHDC was eluted with @entity1042 -water (7:3) mixture. NHDC in the eluate was separated on an ODS column and determined with a UV detector (282 nm). The identity of NHDC in foods was confirmed by means of HPLC with a photodiode-array detector. The recoveries of NHDC added to various kinds of foods were 75.2-134%. The determination limit of NHDC was 1 microgram/g.
