Celery is a widely used vegetable known for peculiar sensorial and nutritional properties. Here, the white celery (Apium graveolens L.) "sedano bianco di Sperlonga" PGI ecotype was investigated to obtain the metabolic profile of celery edible parts (blade leaves and petioles) also related to quality, freshness and biological properties. A multimethodological approach including NMR, MS, HPLC-PDA, GC-MS and spectrophotometric analyses was proposed to analyse celery extracts. Sugars, polyalcohols, amino acids, organic acids, phenols, sterols, fatty acids, phthalides, chlorophylls, tannins and flavonoids were detected in different concentrations in blade leaf and petiole extracts indicating celery parts as nutraceutical sources. The presence of some phenols in celery extracts was here reported for the first time. Low contents of biogenic amine and mycotoxin confirmed celery quality and freshness. Regarding the biological properties, ethanolic celery extracts inhibited the oxidative-mediated DNA damage induced by tert-butylhydroperoxide and scavenged DPPH and ABTS radicals.

Abstract

Celery is a widely used vegetable known for peculiar sensorial and nutritional properties. Here, the white celery (Apium graveolens L.) "sedano bianco di Sperlonga" PGI ecotype was investigated to obtain the metabolic profile of celery edible parts (blade leaves and petioles) also related to quality, freshness and biological properties. A multimethodological approach including NMR, MS, HPLC-PDA, GC-MS and spectrophotometric analyses was proposed to analyse celery extracts. Sugars, polyalcohols, amino acids, organic acids, phenols, sterols, fatty acids, phthalides, chlorophylls, tannins and flavonoids were detected in different concentrations in blade leaf and petiole extracts indicating celery parts as nutraceutical sources. The presence of some phenols in celery extracts was here reported for the first time. Low contents of biogenic amine and mycotoxin confirmed celery quality and freshness. Regarding the biological properties, ethanolic celery extracts inhibited the oxidative-mediated DNA damage induced by tert-butylhydroperoxide and scavenged DPPH and ABTS radicals.
