AFW, extracts from Akebia quinata fruit by hot-water; ALW, extracts from Akebia quinata leaf by hot-water; ASW, extracts from Akebia quinata stem by hot-water; AFE, extracts from Akebia quinata fruit by 70% ethanol; ALE, extracts from Akebia quinata leaf by 70% ethanol; ASE, extracts from Akebia quinata stem by 70% ethanol.
BHT was used as a control substance.
All values are mean±SD (n=5).
Means with different superscript letters (^a-g) in the same column are significantly different at p<0.05 by Duncan’s multiple range test (a>b>c>d>e>f>g).
