Nordihydroguaiaretic acid treatment on the antioxidant properties of strawberry fruit

‘Benihoppe’ strawberry treated with nordihydroguaiareticacid (NDGA) as materials, the main bioactive compounds and antioxidation capacity of fruits were studied and compared. In the experiment, the contents of anthocyanin, vitamin C, flavonoid and total phenol and the antioxidant ability (FRAP) of strawberry fruit were measured. The results showed that NDGA had no obvious effect on the content of anthocyanin and flavonoid of strawberry, but the inhibitory effect on the content of total phenol, vitamin C and antioxidant activity were observed, and especially the inhibition of total phenol was the most. Taken together, nordihydroguaiaretic acid treatment inhibited the antioxidant activity of strawberry fruits.‘Benihoppe’ strawberry treated with nordihydroguaiareticacid (NDGA) as materials, the main bioactive compounds and antioxidation capacity of fruits were studied and compared.
