Natural Product Identification

Common Name

Protobassic acid

Description

Protobassic acid, also known as protobassate, belongs to the class of organic compounds known as triterpenoids. These are terpene molecules containing six isoprene units. Protobassic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, Protobassic acid has been detected, but not quantified in, fruits and guava. Protobassic acid is found in Centella asiatica, Picrorhiza kurrooa and Sideroxylon foetidissimum. This could make protobassic acid a potential biomarker for the consumption of these foods.
