摘要：Steroidal saponins are important class of components found in plants that play several crucial bioactivities based on previous studies. One known steroidal saponin was successfully isolated from Dracaena umbratica, a shrub of Dracaenaceae family. Dracaena umbratica also known as ‘Senjuang’ among local people. The isolation of a white amorphous steroidal saponin was conducted via normal phase vacuum liquid chromatography eluted with methanol. Its structure was established by spectroscopic analysis as 3-O-[α-L-rhamnopyranosyl (14)-α-L-rhamnopyranosyl (14)-β-D-glucopyranosyl]-25(R)-spirost-5-en-3β-ol
