The root bark contains 12% of tannin and cyclopeptide alkaloids—num- mularines A, B and C, mucronine D and amphibine H. The leaves contain ascorbic acid. Nummularine M, R and S, besides frangufoline have been isolated from the stem bark. Num- mularine R and S showed antibacterial activity against Gram-negative bacteria, while frangufoline was active against both Gram-negative and Gram-positive bacteria. The alkaloid fraction, obtained from the bark, showed significant analgesic activity.
