Two novel triterpenoid glycosides, anemoclemosides A and B, were isolated from the roots of Anemoclema glaucifolium, along with four known compounds. The structures of anemoclemosides A and B were established mainly by NMR techniques. The two glycosides have the straight chain form of arabinose attached in acetal form to the aglycone. This is the first example of such glycosides from natural sources.
