A new oleanolic acid-derived saponin, polyacetyleneginsenoside-Ro (1), was isolated along with the known ginsenosides-Ro methyl ester (2), -Rf, -Rg1, -Rg2, and gingerglycolipid B from the roots of Panax ginseng C. A. Meyer. The new saponin was identified as a ginsenoside-Ro derivative containing a polyacetylene side chain by spectroscopic means including 1D and 2D NMR, and was found to inhibit the replication of human immunodeficiency virus type 1 (HIV-1) with an IC50 value of 13.4 μg/mL (11.1 μM).
