A method is presented for the isolation, separation and determination of sparteine and its metabolites in urine. The isolation is based on rapid extraction with dichloromethane and pentane in a glass separator. For the separation and determination, capillary gas chromatography with
The (3S)-[(benzyloxycarbonyl)ethyl]-1,4-dioxan-2,5-dione (BED) was prepared in four steps starting from glutamic acid and bromoacetyl bromide. According to X-ray diffraction analysis, the pendant functional group is located in equatorial position and points away from the six-membered ring. The
The antiproliferative effect of different extracts obtained from Retama monosperma L. was investigated on human SiHa and HeLa cervical cancer cell lines using a MTT colorimetric assay. The Retama monosperma L. dichloromethane fraction (Rm-DF) was the most active extract, exhibiting a significant
