Family: Symplocaceae

Bengali/Vernacular Name: Lodh.

English Name: Californian Cinchona, China Nora, Lodh Tree.

Description of the Plant:
A small evergreen tree with broad crown, up to 6 m high. Leaves 9-18 cm long, elliptic-oblong or elliptic-lanceolate, apex acute obtusely-acuminate or obtuse, serrulate, obscurely crenate or rarely entire. Flowers 1-1.3 cm diam., white or fading yellow, in simple axillary pubescent racemes, 1.3-9 cm long. Drupe 1-1.3 cm long, oblong, purplish black.

Using Information:
The bark is cooling, astringent to the bowels, alexiteric, aphrodisiac and emmenagogue. Cures watery eyes and ophthalmia; good for all diseases of the eyes. Useful in dysentery, bowel complaints, inflammations, vaginal discharges, leprosy, abortion and miscarriages. The fresh bark is given in menorrhagia; a decoction is used as a gargle for giving firmness to bleeding and spongy gums.

Aquous extract of the stem bark showed CNS depressant, analgesic and antidiarrhoel effect in albino mice. The extract also caused contraction of the isolated tracheal chain preparation and slight relaxation of isolated guineapig ileum preparation (Sahriar et al., 2000).

Chemical Constituents:
Two new monomethyl pelargonidin glucosides (I and II) and pelargonidin-3-O-glucoside have been isolated from trunk bark (Rastogi & Mehrotra, 1993). Bark contains two alkaloids, loturine and colloturine (Chopra et al., 1992). 5-β-sitosterol and its glycoside, 3-O- β-D-glucopyranosyl-2-α-3- β-19- α-23-tetra-hydroxyolean-12-en-28-oic acid also have been isolated from the bark. Two new analogous glycosides have also been isolated from the bark and identified as 3, 28-O-bis- β-D-glucopyranoside of α-hydroxyarjunolic and 19- α-hydroxyasiatic acids. Three alkaloids, viz., loturine, loturidine and eloturine are present in the bark (Sahriar et al., 2000).
