Phenolic Contents and Antioxidant Activity of Lily Flower Petals

doi:10.7506/spkx1002-6630-201307012

Abstract

Abstract: The contents of phenols including 15 phenol monomers and antioxidant activity of four cultivated varieties of liliy flower petals were tested. The antioxidant activity of petal extracts was evaluated by measuring scavenging ability against ABTS+·, DPPH and hydroxyl free radicals, reducing power and metal-chelating ability. Flower petals of “Sorbonne” was found to contain the highest phenol content followed by “Siberia”, “Manissa” and Lilium regula. Different types of polyphenol monomers were found in the studied varieties of lily petals and catechin, epicatechin, pcoumaricacid, delphinidin, rutin, dihydromyricetin, dihydroquercetin and kaempferol were simultaneously present in them. In addition, phenols from 4 varieties showed strong radical scavenging activity against ABTS+·, DPPH and hydroxyl free radicals, copper ion reducing power and metal-chelating capacity. Our results indicate that these selected lilies can be developed and utilized in practice as promising sources of natural antioxidants.

Key words: lily, phenolic substances, antioxidant activity
