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).


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.



The stem bark is crushed and the prepared paste is applied externally on bone fracture, joints dislocation and sprains, and bandaged for 3- 7days. During the course of treatment, the decoction of bark (about 200 ml) is orally administered at bedtime. Decoction of the stem bark adding few amount of sugar is administered orally in case of body ache.Freshly collected stem bark is heated over hot oven and placed on the affected area of gout and osteo arthritis to relieve pain.
