Objective:
To study the chemical composition of Opuntia dillenii.
Method:
Many kinds of chromatography methods were used in the isolation procedure, while the structures of isolated compounds were determined on the aids of NMR and MS spectral analysis.
Result:
A new compound, together with five known compounds, was isolated form the 80% ethanolic extract of its stems.
Conclusion:
The new compound was characterized as opuntioside. Four compounds were obtained for the first from the genus Opuntia, and they were daucosterol, p-hydroxybenzoicacid, L-(-)-malic acid, (E)-ferulic acid. Opuntiol was also separated for the first from the plant.
