20-O-?-d-Xylopyranos-yl(1?6)-?-d-glucopyranosyl-20(S)-protopanaxadiol methanol solvate.

ABSTRACT: The title compound, C(41)H(70)O(12)·CH(4)O, was prepared by microbial transformation. Within the steroid skeleton of the mol-ecule, three six-membered rings exhibit a chair conformation, while the five -membered ring adopts an envelope conformation. The two pyranosyl rings also adopt chair conformations. The mol-ecules are held together by an extensive O-H?O hydrogen-bonding network.
