identified according to physicochemical properties and spectrum (mass spectrum,hydrogen spectrum,carbon spectrum) data.
Using human cervical cancer HeLa cells as objects,5-FU as positive control,MTT assay was used to detect the inhibitory rate of
HeLa cells pretreated with different doses of compounds(6.25,12.5,25,50,100,200 µg/mL);IC50 was calculated to screen
active monomers. Scratch test was used to investigate the effects of above active monomers(all 50 µg/mL)on the migration ability
of HeLa cells. Kim’s formula was used to evaluate the effects of 5-FU separately combined with above active monomers [(3.125+
6.25),(6.25+12.5),(12.5+25),(25+50)µg/mL]. RESULTS:Six compounds were isolated from the n-butanol extract part of A.
sparsifolia and identified as butin ( Ⅰ ), 3′,4′,7-trihydroxyisoflavone ( Ⅱ ), p-methoxyphenylacetic acid ( Ⅲ ),
4-hydroxyacetophenone(Ⅳ),aurantiamide acetate(Ⅴ),protocatechualdehydea(Ⅵ). Compared with blank control group,5-FU
and each compound(5-FU:6.25-200 µg/mL,compound Ⅰ:12.5-200 µg/mL;compound Ⅱ:25,50,200 µg/mL;compound
Ⅲ:6.25,100,200 µg/mL;compound Ⅳ:50,100,200 µg/mL;compound Ⅴ:12.5,25,200 µg/mL;compound Ⅵ:6.25-200
µg/mL)could significantly increase the cell inhibition rate. IC50 of compound Ⅰ,Ⅴ,Ⅵ were decreased significantly(P<0.05 or
P<0.01),and those of compound Ⅰ and Ⅵ were lower relatively. The migration distance of cells in 5-FU and compound Ⅰ and
Ⅵgroups were decreased significantly,compared with blank control group(P<0.05 or P<0.01). 5-FU separately combined with
compound Ⅰ and Ⅵ showed additive and enhanced inhibitory effects on the proliferation of HeLa cells(synergistic index>0.9).
CONCLUSIONS:Compounds Ⅰ - Ⅵ are isolated from Alhagi for the first time. Butin and protocatechualdehydea are active
monomers of its n-butanol extract part. Above two monomers can inhibit the proliferation and migration of human cervical cancer
Hela cells,with strong inhibitory effect in vitro,and stronger inhibitory effect combined with 5-FU than any compound alone.
