Coumestans, such as (88), which possess a coumarin strac-ture, are derivatives of isoflavones (Fig. 11.28) most of the 31 known compounds of this stmctural type are restricted to the Fabaceae (Dewick, 1982,1988 Williams and Harbome, 1989b). Study of the biosynthesis of coumestans has been accomplished because elicitors stimulate synthesis of these compounds in plant cell cultures (Grisebach, 1985). The only known coumestan glycoside occurs in Eclipta alba (Asteraceae).

No naturally occurring bi and trithiophenes are currently used as drugs. However, plants containing such compounds have been used in traditional medicine. For example, the juice of Eclipta alba leaves has reportedly been used in India for the treatment of vitiligo, athlete s foot, ringworm and some chronic skin diseases 234 but whether any pharmacological activity must be attributed to a-terthienyl or congeners present in this plant has not been established with certainty.
