Picrasma quassioides is a fine source of alkaloids, terpenoids and quassinoids.
This sub-shrub is a member of the Simaroubaceae family.
Most of the bioactives are alkaloids. These alkaloids can be divided into the following classes: β-carbolines, canthinones and alkaloid dimers (Qian-Wen et al., 2022).
The various bioactive molecules have numerous pharmacological benefits, such as anti-inflammatory, anticancer, and anti-viral effects, on the cardiovascular system. The stems are one of the main sources of these compounds. Quassidine A was the first reported bis-β-carboline alkaloid possessing a novel cyclobutane unit ( Jiao et al., 2010) which makes it highly unusual.
