Bankalanan is an erect or spreading, branched, half-woody shrub, usually less than 1 meter high. Leaves are oblong-ovate, and 2 to 6 centimeters long, with pointed tip and broad, rounded, or heart-shaped base. Flowers are somewhat crowded in terminal or axillary heads. Petals are obovate, white, pink or pale purple, and about 7 millimeters long. Fruit is a small capsule, depressed-globose, 4 to 5 millimeters in diameter, green, whitish or pink to purplish black. Cells are 1-2 seeded. Seeds and small and wingless. Endosperm is abundant.

- A weed common in waste places, open grasslands, fallow fields, settled areas, etc., at low and medium altitudes throughout the Philippines
- Pantropic.
- Prevalent in tropical areas of Africa, Asia, and Australia.
- Reported in Peninsular Malaysia

- Phytochemical screening of leaves of M. corchorifolia yielded triterpenes (friedelin, friedelinol, and ß-amyrin), flavonol glycosides (hibifolin, triflin, and melocorin), aliphatic compounds, flavonoids (vitexin and robunin), ß-D-sitosterol and its stearate,-D-glucoside, and alkaloids.
- Study yielded adouetine and a new cyclopeptide alkaloid, melofoline.
- Study isolated a cyclopeptide alkaloid, franganine, and a new pseudooxindole alkaloid, melochicorine.
- A glycoside, melocorin, was isolated from the leaves of M. corchorifolia along with hibifolin and trifolin.

- Dried powdered leaves show (by dry weight content %): a high crude protein content (23%), crude lipid value (13.33%), low carbohydrate (2.83%), high dietary fiber (23.33%), high ash (10%). Fresh leaves have a low energy value (275 kcal/100g).
- Contains dietary minerals: potassium, calcium, and magnesium.

Parts used

Flavonoids / Antifungal:
Aerial parts of M. corchorifolia yielded 5,7-dihydroxyflavone, apigenin, kaempferol and quercetin. The flavonoids exhibited significant antifungal activity.
Antifeedant / Insecticidal / Ovicidal: Study evaluated the antifeedant, insecticidal, oviposition deterrent and ovicidal activity of different fractions obtained from the crude extracts M. corchorifolia against the armyworm, Spodoptera litura. MC showed feeding deterrent activity and significant ovicidal and larvicidal activity. (3)
Hepatoprotective / Antioxidant: Study evaluated extracts of aerial parts of Melochia corchorifolia for hepatoprotective and antioxidant capacity against CCl4-induced liver toxicity in rats. Results showed concentration dependent decrease in serum enzymes and percentage inhibition of free radicals. (6)
Antibacterial: Study evaluated aerial parts of Melochia corchorifolia and Spilanthes acmella for antibacterial activity against eight bacterial strains. Results showed concentration dependent antibacterial activity. (7)
Radical Scavenging Activity: Study of corchorifolia extract showed strong free radical scavenging activity in all tested methods. Antioxidant activity may be due to phenolic compounds flavonoids and tannins. (9)
