摘要：

The title compound, C28H27O5, is triclinic, space group P1 with unit cell dimensions a = 12.763(2), b = 11.130(2), c = 4.764(3) angstrom, alpha = 73.78(3), beta = 82.89(3), gamma = 62.16(1)-degrees, V = 574.8(4) angstrom3, and Z = 1. The pyranose ring has an H-4(5) conformation with some flattening at C-4. Molecular mechanics calculations indicate that the H-4(5) conformation of the pyranose ring in the title compound is the most stable conformation.
