The constituents from the stems of Garcinia cowa Roxb. and their cytotoxic activities.
Three new flavanone glycosides named garccowaside A, garccowaside B, garccowaside C, and three other known compounds were isolated from the ethanol extract of the stems of Garcinia cowa. These structures were established on the basis of spectroscopic evidence. Twelve compounds isolated from the stems of Garcinia cowa were tested for cytotoxic activities.
