NEW IONOL GLYCOSIDES FROM MAERUA CRASSIFOLIA FORSSK GROWN IN ETYPT [PDF]
Bulletin of Pharmaceutical Sciences. Assiut University, 1998 Further investigation of the methanolic extract of the air-dried aerial parts of Maerua crassifolic Forssk (F. Capparaceae) resulted in the isolation of three new ionol glycosides. The structure of the isolated compounds had been established by extensive
