Steroidal saponins from the aerial parts of Dracaena draco and their cytostatic activity on HL-60 cells

Phytochemistry. 1999 Mar;50(5):805-13. doi: 10.1016/s0031-9422(98)00614-1.

Abstract

Chemical examination of the aerial parts of Dracaena draco has led to the isolation of a total of nine steroidal saponins, including five new ones. The structures of the new saponins were determined by spectral data and a few chemical transformations to be (23S,24S)-spirosta-5,25(27)-diene-1 beta,3 beta,23,24-tetrol 1-O-{O-(2,3,4-tri-O-acetyl-alpha-L-rhamnopyranosyl)-(1-->2)-alpha-L -arabinopyranosyl} 24-O-beta-D-fucopyranoside, (23S,24S)-spirosta-5,25(27)-diene-1 beta,3 beta, 23,24-tetrol 1-O-{O-alpha-L-rhamnopyranosyl-(1-->2)-alpha-L -arabinopyranoside}, (23S,24S)-spirosta-5,25(27)-diene-1 beta,3 beta,23,24-tetrol 1-O-{O-(4-O- acetyl-alpha-L-rhamnopyranosyl)-(1-->2)-alpha-L-arabinopyransoide} , (23S)-spirosta-5,25(27)-diene-1 beta,3 beta,23-triol 1-O-{O-alpha-L- rhamnopyranosyl)-(1-->2)-alpha-L-arabinopyranoside} and (23S,24S)-spirosta-5,25(27)-diene-1 beta,3 beta,23-triol 1-O-{O-(4-O-acetyl-alpha-L-rhamnopyranosyl)-(1-->2)-alpha-L- arabinopyranoside}. The isolated saponins were evaluated for their cytostatic activity on leukemia HL-60 cells.
