[Study on chemical constituents from Opuntia dillenii].
ABSTRACT To study the chemical composition of Opuntia dillenii.
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.
A new compound, together with five known compounds, was isolated form the 80% ethanolic extract of its stems.
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.
