deoxocucurbitoside B (9). 结论: 化合物 1~3 均为首次从药西瓜中分离得到.
Abstract
Objective: To study the chemical constituents from Citrullus colocynthis. Method: The compounds were separated and purified from Citrullus colocynthis by using a various chromatographic techniques including colum chromatography over silica gel
ODS and preparative HPLC. Their structures were elucidated by spectroscopic techniques including 1H-NMR
13C-NMR
2D-NMR
ESI-MS and HRESI-MS. Result: Nine compounds were isolated from this plant and their structures were identified as nicotinamide(1)
uracil(2)
isocucurbitacin B(3)
cucurbitacin E(4)
dihydro-cucurbitacin E(5)
cucurbitacin E-2-O-β-D-glucopyranoside(6)
khekadaengoside E(7)
cucurbitacinK-2-O-β-D-glucopyranoside(8)
deoxocucurbitoside B(9). Conclusion: Compounds 1-3 were isolated from this plant for the first time.
