    Journal: Nat Prod Commun; 2014 Jun; 9(6):811-4. PubMed ID: 25115085.
    Abstract:
    The contents, composition and radical scavenging capacity of phenolic compounds from parsnips of various root weights grown in Serbia were examined. The content of phenolic compounds depended on root size, and the highest content was in the group where the samples with the lowest root size were grouped. The content of phenolic compounds varied from 109.7 to 125.3 micromol of chlorogenic acid per g dry extract, i.e.5470.8 to 6245.1 mg per kg fresh weight. Among the identified compounds were quercetin, kaempferol, apigenin and genkwanin glucosides and hydroxycinnamic and caffeoylshikimic acids. The highest antioxidant capacity was found for the group with the lowest root weight; the IC50 values ranged from 1.59 to 2.49 mg mL(-1). There was positive correlation between the total phenolic content and scavenging capacity, and the kaempferol glucosides content could be an indicator of DPPH scavenging capacity of parsnip roots.
