However, the scientific background of these uses has not been established. To date, only in vitro studies support the antimicrobial effect of the seeds, and there are no data on the systemic antibiotic or other clinical effects. Moreover, recent data refer to the adulteration of grapefruit seed products with synthetic antiseptics which may be an explanation for the antimicrobial efficacy of some formulations. The aim of our study was to develop a simple thin-layer chromatography- based method for the quality control of grapefruit seed extracts. Besides the analytical procedure, we report a quick and simple method for the isolation of limonoids from grapefruit seeds. Limonoids are characteristic compounds of the seeds; hence, the detection of these marker compounds may be the basis of grapefruit identification. Further, a thin-layer chromatographic screening for synthetic antiseptics (quaternary ammonium salts) is also part of the quality control procedure.

The structures of the compounds were elucidated by extensive 1D (1H, 13C and JMOD) and 2D (1H–1H COSY, HSQC, HMBC and NOESY) NMR studies and APCIMS and HRESIMS investigations. 6-Acetyl-3,7-dihydroxy-2,2-dimethyl-chromene and 6-acetyl-3-hydroxy-2,2-dimethyl-chromene are biogenetically related to 1-(5-acetyl-2,4-dihydroxy-phenyl)-3-methyl-butan-1-one and 6-hydroxytremetone as all having isoprenoid acetophenone origin. All the isolated compounds were described for the first time from this species; interestingly none of them are related to the metabolites identified from the extracts of the aerial part of the plant.
