Corchorus is a genus of about 40–100 species of flowering plants in the family Malvaceae, native to tropical and subtropical regions throughout the world.[1]

Different common names are used in different contexts, with jute applying to the fiber produced from the plant, and mallow-leaves for the leaves used as a vegetable.

Description[edit]

The plants are tall, usually annual herbs, reaching a height of 2–4 m, unbranched or with only a few side branches. The leaves are alternate, simple, lanceolate, 5–15 cm long, with an acuminate tip and a finely serrated or lobed margin. The flowers are small (2–3 cm diameter) and yellow, with five petals; the fruit is a many-seeded capsule. It thrives almost anywhere, and can be grown year-round.

Taxonomy[edit]

The genus Corchorus is classified under the subfamily Grewioideae of the family Malvaceae. It contains around 40 to 100 species.[2]

The genus Oceanopapaver, previously of uncertain placement, has recently been synonymized under Corchorus. The name was established by Guillaumin in 1932 for the single species Oceanopapaver neocaledonicum Guillaumin from New Caledonia. The genus has been classified in a number of different families including Capparaceae, Cistaceae, Papaveraceae, and Tiliaceae. The putative family name "Oceanopapaveraceae" has occasionally appeared in print and on the web but is a nomen nudum and has never been validly published nor recognised by any system of plant taxonomy.[3]

The genus Corchorus was first described by Linnaeus in his great work Species Plantarum (1753). It is derived from the Ancient Greek word κόρχορος or κόρκορος (korkhoros or korkoros) which referred to a wild plant of uncertain identity, possibly jute or wild asparagus.[4][5]

Uses[edit]

Fiber[edit]

Main articles: Jute and Jute cultivation

The fibers from Corchorus (known as jute) are the most widely cultivated vegetable fiber after cotton.[6]

Food[edit]

In Thai cuisine, the leaves are known as bai po

Note: On September 11, 2014 a report appreared that this plant could be used to cure the Ebola virus disease. This report is suspect. It is best that anyone that arrived here on this page based upon a hope that it is a cure, should only consider that report to be a rumor.

Corchorus leaves are consumed in the cuisines of various countries. Corchorus olitorius is used mainly in the cuisines of southern Asia, the Middle East, and North Africa, Corchorus capsularis in Japan and China. It has a mucilaginous (somewhat "slimy") texture, similar to okra, when cooked. The seeds are used as a flavouring, and a herbal tea is made from the dried leaves. The leaves of Corchorus are rich in betacarotene, iron, calcium, and vitamin C. The plant has an antioxidant activity with a significant α-tocopherol equivalent vitamin E.[citation needed]

In North Africa and the Middle East, the young leaves of Corchorus species are known in Arabic as malukhiyah and are used as green leafy vegetables . Malukhiyah is eaten widely in Egypt and some consider it the Egyptian national dish. It is featured in cuisines from Lebanon, Palestine, Syria, Jordan and Tunisia. In Turkey and Cyprus, the plant is known as molohiya or molocha and is usually cooked into a kind of chicken stew.[7] The leaves of Corchorus have been a staple Egyptian food since the time of the Pharaohs and it is from there that it gains its recognition and popularity. Varieties of mallow-leaves stew with rice is a well known Middle Eastern cuisine.

In Nigerian cuisine, especially amongst the Yorubas, it is commonly used in a stew known as ewedu, a condiment to other starch-based foods such as amala. The Hausa people of Nigeria and their Fula neighbours call it rama. They use it to produce soup (taushe) or boil the leaves and mix it with kuli-kuli (groundnut cake) to form a dish known as kwado in Hausa. The Hausa peasant farmers cultivate it beside their corn-stalk constructed homesteads or among their main crops in their farms. The Hausa and Fulbe peoples also use jute leaves to treat some diseases.

In Sierra Leone it is known as krain krain (or crain crain) and is cooked as stew. The stew is usually eaten with rice or foofoo (a traditional food made from cassava).[8][7]

Jute leaves are also consumed among the Luhya people of Western Kenya, where it is commonly known as mrenda or murere. It is eaten with starchy foods like ugali, a staple for most communities in Kenya.[9] In Northern Sudan it is called khudra, meaning "green" in Sudanese Arabic. The Songhai people of Mali call it fakohoy.

In India, it is locally known as nalta sag. It is a favorite food during the summer months, especially in Sambalpur and the western part of Odisha. Usually it is lightly sauteed and eaten along with rice or rice gruel.

In the Philippines, C. olitorius is known as saluyot. It is commonly consumed as a leafy vegetable together with bamboo shoots.[10]

In Thai cuisine, the leaves of the Corchorus olitorius (locally known as bai po; Thai: ใบปอ) are eaten blanched, together with plain rice congee. The taste resembles that of spinach and samphire.

In Ghana, it is mostly taken by the people in the North and it is called Ayoyo. It is mostly eaten with Tuozaafi (food prepared with cornflour).
