Phytochemistry
8- acetyl- 7- hydroxy- 6- methoxycoumarin, 8- methoxy coumarin and 2,5- dihydroxy- 6-methoxyacetophenone isolated from leaves together with fraxetin and esculetin (Phytochemistry 1980, 19, 2494) a new courriarin- floribin- isolated from bark and characterised (Pharmasize 1983, 38, 72; Chem Abstr 1983, 98, 2128145).
Agrocultivation
The plant is propagated through seeds. They are occasionally cultivated. Seeds are shown in nurseries in autumn or spring germination taking place in spring 7 or 12 months later as the case may be. Seedlings, about 2 seasons old, are transplanted in winter.
Medicinal
