Description of the Alternanthera sessilis
Annual or usually perennial herb; in drier situations with slender, more solid stems, erect, ± much-branched, to c. 30 cm; in wetter places ascending or commonly prostrate with stems c. 0.1-1 m long, rooting at the nodes, ± fistular, with numerous lateral branches; when floating very fistular, the stems attaining several metres in length and over 1 cm thick, with long clusters of whitish rootlets at the nodes. Stem and branches green or purplish, with a narrow line of whitish hairs down each side of the stem and tufts of white hairs in the branch and leaf axils, otherwise glabrous, striate, terete. Leaves extremely variable in shape and size, linear-lanceolate to oblong, oval, or obovate-spathulate, 1-9 (-15) x 0.2-2 (-3) cm, blunt to shortly acuminate at the apex, cuneate to attenuate at the base, glabrous or thinly pilose, especially on the lower surface of the midrib; petiole obsolete or up to c. 5 mm. Inflorescence sessile, axillary, solitary or in clusters of up to c. 5, subglobose (or somewhat elongate in fruit), c. 5 mm in diameter; bracts scarious, white, deltoid-ovate, mucronate with the excurrent pale midrib, glabrous, c. 0.75-1 mm; bracteoles similar, 1-1.5 mm, also persistent. Tepals oval-elliptic, equal, 1.5-2.5 mm, acuminate to rather blunt, white, glabrous, shortly but distinctly mucronate with the stout, excurrent midrib, the margins obscurely denticulate. Stamens 5 (2 filaments anantherous), at anthesis subequalling the ovary and style, the alternating pseudostaminodes resembling the filaments but usually somewhat shorter. Ovary strongly compressed, roundish, style extremely short. Fruit obcordate or cordate-orbicular, 2-2.5 mm long, strongly compressed with a narrow, pale, somewhat thickened margin. Seed discoid, c. 0.75-1 mm, brown, shining, faintly reticulate.

Distribution: A common species, very widepsread in the tropics and subtroprics of both Old and New Worlds in waste and cultivated ground, especially in damp or wet conditions.

Medicinal Uses of Alternanthera sessilis in District Badin, Sindh:
Leaves are used against infection of cut or injury.

1. Method of use for injury:
Make the paste of 10 g fresh leaves and add 5 mL hair oil and apply on the affected area twice a day the quantity can increased according to size of cut or injury.

Previous studies on Alternanthera sessilis:
It has been reported that A. Sessilis possess-antibacterial activity.
It has also been reported that it can be used against the common cold and allaying fever.

Following are the compounds isolated from Alternanthera sessilis:
A mixture of diastereomers of a new ionone deriv. (I) from the chloroform ext. of the air-dried leaves of Alternanthera sessilis.



Major components are saponins from leaves of A. sessilis contain a 3b-O-(b-D-glucopyranosyluronic acid). 28-O-b-D-Glucopyranosyl oleanolic acid.

A saponin having oleanolic acid as aglycon and glucose and rhamnose as sugar moieties. Lupeol (m.p. 213°, [a]D20+ 26.40°) from the petroleum ether ext. of dried powd. roots of A. sessilis.
