Abstract

Abstract: In this experiment, the main bioactive substances and antioxidant activities of flower buds and leaves in different developmental stages were measured with three Flos Lonicerae varieties (lines) 'Hong Lei Yi Hao', 'Yin Cui Lei' and "Cui Lei 109" as materials, and their correlation was analyzed. The results showed that the polyphenols and flavonoids gradually decreased and then increased with the growth and development of leaves, and they were the highest in young leaves, followed by old leaves. The Vitamin c (Vc) content of the three varieties (lines) was the highest in old leaves, followed by young leaves, and there was no significant difference among the varieties (lines). The polyphenol content and flavonoid content in Flos Lonicerae were positively correlated with DPPH free radical scavenging rate, while the correlation between Vc content and antioxidant activity was low or negatively correlated.
