ChEBI: Akebia saponin D is a triterpenoid saponin that is hederagenin attached to a alpha-L-arabinopyranosyl residue at position 3 via a glycosidic linkage and a 6-O-beta-D-glucopyranosyl-beta-D-glucopyranosyl residue at position 28 via an ester linkage. It is the active ingredient found in the traditional Chinese herb Radix Dipsaci. It has a role as an apoptosis inducer, an antineoplastic agent, a plant metabolite, an anti-inflammatory agent, a bone density conservation agent, a neuroprotective agent and an antilipemic drug. It is a triterpenoid saponin, a trisaccharide derivative, a pentacyclic triterpenoid and a carboxylic ester. It is functionally related to a hederagenin.
