Phytochemical Properties and Health Benefits of Smallanthus Sonchifolius

Smallanthus sonchifolius, commonly known as yacon, is an Andean perennial valued for its tuberous roots and leaves, which are rich in fructooligosaccharides (FOS), inulin, phenolic acids, flavonoids and sesquiterpene lactones. The unique carbohydrate profile confers prebiotic benefits, fostering bifidogenic growth in the gut, while phenolic acids—particularly caffeic and chlorogenic derivatives—provide potent antioxidant and anti‐inflammatory activity. Sesquiterpene lactones such as enhydrin and uvedalin contribute additional pharmacological properties, including modulation of glucose uptake and anti‐diabetic effects. Collectively, these phytochemicals underpin a spectrum of health benefits: glycaemic control, lipid regulation, reduction of advanced glycation end‐products, enhancement of intestinal microbiota composition, and protection against oxidative stress. Applications range from functional foods (flours, syrups, teas) and dietary supplements to standardised extracts for herbal medicine. Global interest has surged as cultivation expands beyond South America, offering sustainable crop diversification and novel dietotherapy opportunities.

Phytochemical Properties and Health Benefits of Smallanthus Sonchifolius publication trend

The graph below shows the total number of articles in phytochemical properties and health benefits of smallanthus sonchifolius across all publications each year (not limited to Nature Index journals).

Technical terms

Fructooligosaccharides (FOS): Oligosaccharide carbohydrates resistant to digestion that promote growth of beneficial gut bacteria.

Inulin: A polysaccharide composed of fructose units acting as dietary fibre and prebiotic substrate.

Sesquiterpene lactones: Terpenoid compounds containing a lactone ring, noted for anti‐inflammatory and cytoprotective effects.

Phenolic acids: Aromatic secondary metabolites (e.g. caffeic and chlorogenic acids) with antioxidant and anti‐glycation properties.

Alpha‐amylase inhibition: The reduction of enzyme activity that breaks down starch, leading to moderated postprandial glucose levels.

In silico analysis: Computational modelling methods used to predict molecular interactions and biological efficacy.

PPAR-γ: Peroxisome proliferator-activated receptor gamma, a nuclear receptor regulating lipid and glucose metabolism, targeted by antidiabetic compounds.
