Terpenoids from Stems and Leaves of Aphanamixis grandifolia
(Meliaceae),has effects in soothing activating collaterals,dredging paisy,expelling wind-evil and removing wetness. This paper aimed to investigate terpenoids from the stems and leaves of
A. grandifolia
and reveal the effective substances.
Method
2
Totally 22 kg leaves and twigs of
A. grandifolia
were extracted with 90% EtOH for three times by heating reflux. These extracts were decompressed and concentrated,and then dissolved in water. The solvent was successively extracted with petroleum ether and ethyl acetate. The chemical constituents from petroleum ether and ethyl acetate fractions were isolated by macroporous,silica gel,Sephadex LH-20 and ODS columns,and their chemical structures were determined through MS,NMR analysis(
1
H and
13
C-NMR)and spectroscopic data from literatures,respectively.
Result
2
Twelve compounds were obtained and identified as 16
