Objective:To investigate chemical constituents and antioxidant activities of Lindera aggregata.Method: Silica gel chromatography
D-101 macroporous resin and sephadex LH-20 were used for separation.Spectroscopic techniques were used for structure identification of compounds.1
1-diphenyl-2-picrylhdrazyl radical(DPPH) method was used for antioxidant activities bioassay of seven compounds.Result: Twelve compounds were obtained and determined to be hernangerine(1)
syringgaresinol(2)
vanilin(3)
α-cadinol(4)
p-hydroxybenzaldehyde(5)
β-sistosterol linoleate(6)
epicatechin(7)
boldine(8)
norboldine(9)
norboldine acetate(10)
daucosterol(11) and β-sitosterol(12).The antioxidant activities of compounds 1
2
3
4
7
9 and 10 were evaluated through DPPH assay.Conclusion: Compounds 1-6 were isolated from this genus for the first time.Compounds 2 and 7 exhibited moderate antioxidant activities.
