EtOH(50%) extract of the leaves is hypoglycaemic, spasmolytic and antiprotozoal (Asolkar et al., 1992).

Chemical constituents:
Leaves, roots and seeds contain the alkaloids, ankorine, marckidine, marckine, tubulosine, alangicine, cephaeline, psychotrine, etc.; steroids and triterpenoids. Plant (root, leaves and fruit) also yield monoterpenoid lactam, alangiside, loganic acid, venoterpine, dl-salsoline and isocephaeline. Leaves also contain alkaloids, deoxytubulosine, alangimarckine, dehydroprotoemetine etc. Root bark contains the alkaloids, emetine, cephaeline, psychotrine, tubulosine, isotubulosine alangium A, alangium B, marckidine, marckine, and alangine, and also myricyl alcohol, stigmasterol and ß-sitosterol. Root also contains de-Me-psychotrine and a new alkaloid, alangicin. Stem bark contains the alkaloids, alangine, akharkantine, akoline and lamarkine.

Seven tetrahydroisoquinoline monoterpene glucosides have been isolated from the fruits. Seed alkaloids include emetine, cephaeline, N-methylcephaeline and psychotrine. They also contain betuline, betulinaldehyde, lipeol, betulinic acid and ß-sitosterol. Stigmasta- 5, 22, 25- trien-3ß-ol, myristic acid, E-cis- fused neohopane derivetives, alangidiol and its isomer; N- benzoyl-L-Ph-alaninol, and 3 unidentified triterpenoids also isolated from the plant (Asolkar et al., 1992; Ghani, 2003).
