Phytochemical Properties of Triterpenoid Saponins
Summary
Triterpenoid saponins are plant‐derived amphiphilic glycosides consisting of a hydrophobic triterpene aglycone core and one or more sugar chains. They exhibit pronounced surface‐active properties, enabling interaction with biological membranes and the formation of pores that underlie haemolytic and adjuvant activities. Structural diversity arises from variations in the aglycone skeleton (commonly oleanane, ursane or lupane), the number and position of sugar residues and the nature of linkages. These structural features influence solubility, membrane affinity and bioavailability. Phytochemical investigations have revealed saponins in a wide range of species, where they function in defence and signalling. Their broad pharmacological profile encompasses anti‐inflammatory, immunomodulatory, anticancer and cardiometabolic effects. Extraction and characterisation typically employ chromatographic separation coupled with mass spectrometry and nuclear magnetic resonance to resolve complex mixtures. An improved understanding of structure–activity relationships has fostered the development of saponin‐derived therapeutics and vaccine adjuvants, underscoring their global significance and translational potential.
