Chemical Constituents from Stems of Zanthoxylum bungeanum
To isolate and identify the chemical constituents from 95%ethanol extracts from stems of
Zanthoxylum bungeanum
.
Method:
2
The stems (25 kg) were extracted with 95%ethanol under reflux for three times and then filtrated
and the combined filtrates were concentrated under vacuum to get the extracts. After suspension with water
the extracts were extracted with petroleum ether
dichloromethane
ethyl acetate and n-butanol successively
and five corresponding parts were obtained. The parts of petroleum ether
dichloromethane
ethyl acetate were separated in a similar way to get pure compounds. By the method the subjects were first chromatographed on silica gel column respectively
then the selected sub-fractions were further separated by Sephadex LH-20
and finally purified on preparation HPLC to get the monomer compound. The
n
-butanol part was first treated with macroporous resin D101
and then the sub-fractions were further purified by almost the same method as mentioned above. The structures of these compounds were determined by spectrum technology as IR
MS
1
H-NMR
13
C-NMR.
Result:
2
Ten compounds were isolated from
Z

)
(-)-columbianetin(
3
)
(-)-decursinol(

)
β
-amyrin(

)
δ
-amyrin(

were flavonoids.
Conclusion:
2
Compounds 1-8 were isolated from this plant for the first time.
