Objective: To reveal the chemical material foundation of active components in water decoction of Fengshao Liujunzi. Moreover

in order to develop and utilize them comprehensively

this paper studies the chemical constituents systematically. Method: According to extraction of the traditional decocting method

the components were isolated by silica gel column

Sephadex LH-20

macroporous adsorption resin D101

ODS-C18 repeatedly

and compounds structures were identified by spectral analysis. Result: Thirteen compounds were isolated and identified as β-sitoster (1)

palmitic acid (2)

isomultiflorenol (3)

triacontanol (4)

psoralen (5)

atractylenolidⅢ (6)

p-hydroxybenzaldehyde (7)

gallic acid (8)

benzoic acid (9)

nobiletin (10)

sinensetin (11)

tangeritin (12)

lactiflorin (13). Conclusion: thirteen compounds above were isolated from the decoction for the first time. Gallic acid may be one of the main active constituents of the decoction.
