ABSTRACT
Three new spirostan glycosides, dracochinosides A-C (1-3), and four known steroidal glycosides (4-7) were isolated from the aerial parts of Dracaena cochinchinensis (Lour.) S.C.Chen. Their chemical structures were determined by the IR, HR-ESI-MS, 1D-, and 2D-NMR spectra. Compounds 1-3, 6 and 7 inhibited nitric oxide production in LPS activated RAW 264.7 cells with IC50 values ranging from 57.5 to 92.8 µM. In addition, all the isolated compounds exhibited at least one of seven tested microbial strains with the MIC values ranging from 0.016 to 0.128 mg/mL. This is the first report of compounds 5-7 from the genus Dracaena.
