Hederagenin is the aglycone part of numerous saponins found in Hedera helix (common ivy), the most prevalent of these being hederacoside C and alpha-hederin. It is also one of three primary triterpenoids extracted from the Chenopodium quinoa plant categorized by the EPA as a biopesticide.[1] HeadsUp Plant Protectant is made up of approximately equal ratios of the saponin aglycones oleanolic acid, hederagenin, and phytolaccagenic acid and is intended for use as a seed treatment on tuber (e.g. potato seed pieces), legume, and cereal seeds or as a pre-plant root dip for roots of transplants, at planting, to prevent fungal growth, bacterial growth, and viral plant diseases.

Hederagenin has been found to have antidepressant-like effects in a rodent models.[2]

History

edit

Hederagenin was discovered by L. Posselt in 1849 and named hederic acid.[3] However, Posselt was not able to isolate a pure substance or obtain an exact formula: his hederic acid was hederagenin mixed with some tannin impurity.[4]

edit

All of these compounds share the same pentacyclic framework:
