Gen info
Corchorus is a genus plant of about 40-100 species in the family Malvaceae. Jute is confusingly applied to any plant of the genus Corchorus and to its fiber. The chief sources of the fiber are the two species of Corchorus plant: C olitorius and C capsularis. In the Philippines, three Corchorus species are recorded with medicinal uses: Pasau, Pasau na bilog, and pasau na hapa. Another pasau, Pasau-na-hapai, Jussiaea erecta belongs to the family Onagraceae.

Pasau-na-bilog is an erect, branched annual herb, growing up to 1 to 2 meters high. Stems are usually purplish. Leaves are ovate-lanceolate, 5 to 12 centimeters long, pointed at the tip and rounded at the base, with toothed margins and tail-like projections on the each side of the midrib. Flowers are in small groups in the axils of the leaves, about 4 millimeters long. Sepals are often purplish and the petals are yellow. Capsules are globose to globose-obovoid, about 1 centimeter in diameter, with longitudinal ridges.

- In clearings, rice paddy banks, and in low, open and usually wet places in and near settlements, throughout the Philippines.
- Pantropic.
- Not cultivated in the Philippines.

- Cultivated in China, India, Bangladesh for its fiber.

- Active principle of the jute seed is corchorin, a glucoside ten times more bitter than quinine sulfate.
- Leaves yield a bitter compound, capsularin, a compound with the same molecular formula and melting point as corchorin.
- From the leaves, capsularin, with the same molecular formula as corchorin.
- Study yielded corchortoxin, another cardiac agent from the seeds.
- Study yielded another bitter, corchsularin from the seeds. (9)
- Seed contains 2.25 percent of raffinose.
- Oil contains the glycerides of oleic acid, 39.18%; glycerides of linolic acid, 44.63 %; a small quantity of "crude archidic acid," 0.169%; and palmitic and stearic acid.
- Leaves yielded a glycoside–capsugenin-30-o-B-glycopyranoside. (5)
- Study of lipid and lignin composition of jute fibers showed the lipohilic compounds as high molecular weight ester waxes (24% of total extract), free fatty acids (17%), free fatty alcohols (17%), and α-hydroxy fatty acids (14%), with significant amounts of alkenes (6%), cohydroxy fatty acids (6%), sterols (6%), steroid and triterpenoids ketones (3%), and steryl glycosides (1%). (10)

- Considered carminative, cardiac, laxative, febrifuge, and tonic.
- Leaves considered stimulant, laxative, demulcent, appetizer and stomachic.
- The corchorin considered toxic and poisonous; some studies suggest a digitalis-effect on the heart.
- Fiber, one of nature's stronger vegetable fibers, is referred to as the "golden fiber." It is long, soft, shiny, 1 to 4 meters in length, with a diameter of 17 to 20 microns, with high insulating and anti-static properties, with moderate moisture regain and low thermal conductivity.
- Studies have suggested antipyretic, anti-inflammatory, and analgesic, insecticidal, antioxidant properties.

Parts used
Seeds and leaves.

Edibility / Nutrition
- Edible: Leaves and seeds.
- In the Philippines, tops eaten as vegetable, particularly by the Ilocanos who call it "saluyut."
Young fresh leaves eaten as vegetable in various parts of the world - Bangladesh, Middle East, Africa, SE Asia.
- In Bengal, where it is considered a tonic, leaves are used as a condiment, commonly added to the daily diet of rice.
- In Japan, considered a health food item, dried leaves sometimes used as a substitute for coffee and tea
Leaves sometimes used as condiment.
- In Rumpf's time, when slaves from India were detained in Amboina, there was much use for it as vegetable.
- Leaves are used for headaches.
- Seeds, either as power or decoction, used as tonic, carminative and febrifuge.
- In Bengal, decoction of dried leaves used for disorders of the liver.
- Malays use a decoction of the leaves for dysentery, for coughs and phthisis, and as a tonic for children. Also, used for poulticing sores.
- The powdered leaves, dried, 1 or 1 1/2 tbsp to a cup of water, steep for 3 to 5 minutes, and strain before drinking.
- Leaves used as stomachic.
- Finely carded fiber sometimes used as base for antiseptic surgical dressings.
- Infusion of leaves used for atonic dyspepsia, liver disorders and as febrifuge. Also used for chronic cystitis, gonorrhea, dysuria, worms in children, hepatic and intestinal colic, and for gastric catarrh.
- Cold infusion of the leaves as a bitter tonic; used in patients recovering from acute dysentery
- A compound infusion of the leaves with coriander and anis seed is an effective bitter stomachic and tonic.
- Poultice of leaves for sores.
- Six grains of the powder combined with equal amounts of Curcuma longa used for acute dysentery.
- A compound infusion of the leaves with coriander and anis seed used as an effective bitter, stomachic and tonic.
- Bitter seeds given in small doses (60-80 grain dose) for fevers.
- Oil from seeds is used for a variety of skin diseases.
- Fruits used by Sino-Annamites for inflammation, abscesses and as purgative.
- In Bengal, oil from the seeds used for skin diseases.
Commerce of Jute
- The species provides the greatest part of the jute commerce (burlap, cordage, gunny), with its strong and coarse fiber, about ten times more abundant than Corchorus olitorius, another source of jute. Jute yarn has replaced flax and hemp in sackcloth. Sacking is the bulk of manufactured jute products. The yarn is also used in weaving curtains, chair coverings, carpets, and rugs. It is blended with other fibers in making toys, decorative wall hangings, lamp shades and shoes. Also used for rigid packaging, reinforcing plastic, and replacing wood in pulp and paper.
- Finely carded and highly absorptive fiber used as basis for antiseptic surgical dressings.
- Used for paper making.

Antinociceptive / Anti-Inflammatory / Leaves:
Study evaluated C. capsularis leaf chloroform extract showed significant (p<0.05) antinociceptive and anti-inflammatory activities in experimental animal models. Results confirm its traditional use for ailments associated with inflammation and pain. (1)
Galactolipid / Anti-Tumor:
Galactolipid 1 has be shown to be responsible for the anti-tumor promoting activity of jute (Corchorus capsularis and C. olitorius). (2)
Antipyretic / Antinociceptive / Anti-Inflammatory:
Study on the aqueous extract of jute plant leaves, C. capsularis, exhibited significant antinociceptive, anti-inflammatory and anti-pyretic activities in a dose-dependent manner and supports its claim of traditional use to treat various ailments.
Capsugenin: Study yielded a glycoside–capsugenin-30-o-B-glycopyranoside, from the leaves of Corchorus capsularis. (5)
• Cardiotonic Activity / Seeds:
Study of seeds isolated a cardiac glycoside chorchortoxin (strophanthidin), a cardiac glycoside that showed cardiotonic activity similar to the digitalis genus. (12)
• Antimicrobial / Insecticidal:
Study evaluated different seed extractives of C. capsularis for antimicrobial and insecticidal activities. All fractions and isolated compounds showed antimicrobial and insecticidal activities against four pathogenic bacteria i.e. V. cholerae, Shigella spp., Salmonella spp., E. coli and the insect T. castaneum. Crude extract showed highest antibacterial activity with inhibition zone of 26-27 mm. In insecticidal activity, the PE fraction showed highest toxicity. (13)
• Chemical Composition of Jute Fibers for Paper Pulp Manufacturing:
Study characterized the lipid and lignin composition of jute fibers. The most prominent lipophilic compounds were high molecular weight ester waxes (24%) followed by free fatty acids (17%), free fatty alcohols (17%), and a-hydroxyfatty acids (14%). There were significant amounts of alkanes, ω-hydroxyfatty acids, sterols, steroid and triterpenoid ketones, and steryl glycosides. (14)
• Caffeine & Catechin / Antioxidant and Cytotoxicity:
Study reported on the isolation of caffeine and catechin from C. capsularis leaves extract. The isolated caffeine showed good antioxidant activity with IC50 of 285 µg/ml and showed moderate cytotoxic effect on Brine shrimp assay. The isolated catechin showed antioxidant effect with IC50 of 432 µg/ml with a total phenol content of 44.25 mg/g. The study sought to establish another new natural source of caffeine and catechin other than tea or coffee. (15)
• Antioxidant Effect:
Crude methanolic extract of C. capsularis leaves and fractions were evaluation for free radical scavenging activity against DPPH and superoxide anion radical scavenging assays. Results showed remarkable antioxidant activity in both assays. Hexane extract showed the most potent antioxidant activity with 65.44-97.43% inhibition, followed by butanol, methanol and EA extracts.
