Abstract
Two glycosides, isolated in good yields from roots of Macfadyena unguis-cati (L.) A. G entry (syn. Doxantha unguis-cati (L.) Miers), gave on hydrolysis the same aglycone (quinovic acid). The sugar moieties have been identified as fucose and glucose respectively. This is the first time that saponins have been found in Bignoniaceae and their occurrence may account of the use of the plant in folk medicine.
