In conclusion, the results indicate that postharvest Nitric figuration
stimulates phenolic and flavonoid accumulation and enhances the
antioxidant activities in the mushroom, which suggests that NO
fumigation might have potential application for enhancing the bio-
active compounds and improving the antioxidant activities in the
mushroom. Moreover, our data demonstrate that the NO-induced
flavonoid and phenolic accumulationmight be due to the activation
of phenylpropanoid–flavonoids pathways in the mushroom
