Compound Monograph
Aspalathin
Aspalathin is a dihydrochalcone flavonoid found almost uniquely in rooibos.
Classification
Aspalathin is a flavonoid (dihydrochalcone c-glycoside), part of the phenolics class. Antioxidant compounds built around one or more phenol rings — the flavonoids, tannins, phenolic acids, coumarins, and pigments behind much of a plant's protective chemistry.
Where Does It Come From? (1)
Aspalathin is a naturally occurring flavonoid (dihydrochalcone c-glycoside), found in Rooibos. It is well tolerated orally (low toxicity).
Research & Evidence
Aspalathin is a C-glycosylated dihydrochalcone flavonoid that is highly characteristic of rooibos (Aspalathus linearis), in which it is the dominant polyphenol and is found in unusually high amounts compared with other plants. It is a major contributor to the antioxidant profile of rooibos tea and has been studied in the laboratory for antioxidant and glucose-related effects.
Toxicity & Safety
Aspalathin is a polyphenol consumed routinely in rooibos tea, a popular caffeine-free beverage, and is regarded as low in toxicity at dietary levels.
