Betulinic acid (ALS-357) is a pentacyclic lupane-type triterpene derivative of betulin (isolated from the bark of Betula alba, the common white birch) which has antiretroviral, antimalarial, and anti-inflammatory properties, as well as a more recently discovered potential as an anticancer agent, by inhibition of topoisomerase.

Protopine (Fumarine) is a benzylisoquinoline alkaloid. It has been found to inhibit histamine H1 receptors and platelet aggregation, and acts as an analgesic.

1. Engeletin (Dihydrokaempferol 3-rhamnoside) may serve as a potential anti-inflammatory agent. 2. Engeletin possesses potent inhibition of PGE2 release with IC5 values of 19.6 μg/ml. 3. Engeletin inhibits a recombinant human aldose reductase (IC5 value=1.16 microM).

Betulin (betulinol) (lup-20(29)-ene-3β, 28-diol) is an abundant, naturally occurring triterpene. It is commonly isolated from the bark of birch trees where it forms up to 30% of the dry weight of the extractive and is found in birch sap as well.

Castanospermine (1,6,7,8-Tetrahydroxyoctahydroindolizine) is a natural compound that inhibits α- and β-glucosidases, especially glucosidase l.
