Abstract This study involves the development and characterization of a series of sodium alginate-based pH-responsive hydrogel microspheres encapsulating poly( d , l -lactic-co-glycolic acid) (PLGA)… Expand
A lupane triterpenoid from Maerua oblongifolia
- M. Abdel-Mogib
- 1 June 1999
Separation of the extract of Maerua oblongifolia afforded, in addition to known compounds, three lupane triterpenoids; one of them is new natural product, which was identified, by one and two… Expand
Sesquiterpene lactones and kaurane glycosides from Francoeuria crispa.
Abstract The aerial parts of Francoeuria crispa gave, in addition to known sesquiterpene lactones, two new ones. From the polar parts a large amount of two diterpene glycosides derived from… Expand
Dammarane triterpenes from Cleome africana
Abstract An extract of the aerial parts of Cleome africana afforded in addition to known compounds two triterpenes of the dammarane type. The structures were elucidated using high field NMR… Expand
