Description of the Plant:
A medium-sized, deciduous or semi-evergreen tree. Leaves 10-25 cm long, elliptic-ovate or oblong-lanceolate, acute or acuminate, more or less grey-tomentose beneath. Flowers small yellowish, about 8-12 together in umbellate heads, 13-16 mm across, arranged in lax, pedunculate ,axillary corymbs. Fruit 7.5 mm, globose, black.
The mucilaginous bark is largely employed as a demulcent and mild astrigent in diarrhoea and dysentery. Freshly ground bark used as an emollient application to bruises and as a styptic dressing for wounds. It is also considered aprodisiac. The oil from the berries is used in rheumatism. The mucilaginous leaves are considered antispasmodic and emollient; useful in colic and impotence. In Rema-Kalenga barks and leaves are used in Diarrhoea and dysentery (Yusuf et al. 2009). Ethanolic extract of the leaves possess good antibacterial activity (Anwar et al., 2007).
Leaves and bark are rich in mucilage and contain an alkaloid, laurotetanine, which causes titanic spasm in animals. Leaves also contain amino acids, cystine, glycine, L-alanine, β-alanine, valine, tyrosine, proline, phenylalanine and leucine. A new flavonoid – naringerin along with naringin, kaempferol-3- and 7-glucosides, quercetin and its 3-rhamnoside, pelargonidin-3- and 5-glucosides have also been isolated from leaves. Seeds yield fatty oil which is a rich source of lauric acid. The essential oil of the fruits contains more than 40 compounds of which β-ocimene occurs in high proportion. Other predominant ones include caryophyllene oxide and β-caryophyllene. Two new alkaloids - sebiferine and litseferine have been isolated from trunk bark. Actinodaphnine, their N-methyl derivatives, boldine and norboldine have also been isolated from this plant (Ghani, 2003; Rastogi & Mehrotra, 1993).
