Cycloartane glycosides from the rhizomes of Curculigo orchioides.

Cycloartane glycosides (1-9) were isolated from rhizomes of Curculigo orchioides (Hypoxidaceae), and this structures were determined by spectroscopic analysis and a few chemical transformations. Cytotoxic activity of glycosides (1-9) and their common aglycone (1a) against HL-60 human promyelocytic leukemia cells was also examined.

Triterpene glycosides from the aerial parts of Larrea tridentata.

Chemical study of the aerial parts of Larrea tridentata (Zygophyllaceae) resulted in the isolation of 25 triterpene glycosides, 13 of which were previously unknown. Their structures were determined on the basis of comprehensive spectroscopic analyses, including 2D NMR spectroscopy, and hydrolytic cleavage followed by chromatographic and spectroscopic analyses. This is the first systematic phytochemical study of L. tridentata with attention paid to its triterpene glycoside constituents. The isolated compounds were evaluated for their cytotoxic activity against HL-60 human promyelocytic leukemia cells.
