Phytochemical investigation of the aerial parts of  Sansevieria trifasciata , one of the most common Dracaenaceae plants, has resulted in the isolation of a new dihydrochalcone derivative named trifasciatine C ( 1 ), four previously unreported steroidal saponins as two pairs of inseparable regioisomers: trifasciatosides K/L ( 2/3 ), M/N ( 4/5 ), together with the known 1,2-(dipalmitoyl)-3- O - β -D-galactopyranosylglycerol ( 6 ), aconitic acid ( 7 ), and 1-methyl aconitic acid ( 8 ). Their structures were elucidated mainly by extensive spectroscopic analysis (1D and 2D nuclear magnetic resonance) and high-resolution electronspray ionization-mass spectrometry, as well as chemical methods and comparison of their spectral data with those of related compounds. Compounds  2/3  and  4/5  were evaluated for their antiproliferative activity on Hela cells, and no significant effect was observed.
