Hibiscuscannabinus is in the genus Hibiscus and is probably native to southern Asia, though its exactnatural origin is unknown. The name also applies to the fibre obtained from this plant. Kenaf isone of the allied fibres of jute and shows similar characteristics. Other names include Bimli,Ambary, Ambari Hemp, Deccan Hemp, and Bimlipatum Jute.It is labelled as Gongoora inIndian, Korean, American food and groceries chains in the United States. Gongoora is fromTelugu. For Telugus it is a favourite food leaf. It is cooked with daal and eaten as saag. Theyeven prepare a kind of pickle with the leaves that lasts for one or two years. It is said to be richin Iron.It is an annual or biennial herbaceous plant (rarely a short-lived perennial) growing to 1.5-3.5 mtall with a woody base. The stems are 1–2 cm diameter, often but not always branched. Theleaves are 10–15 cm long, variable in shape, with leaves near the base of the stems beingdeeply lobed with 3-7 lobes, while leaves near the top of the stem are shallowly lobed orunlobed lanceolate. The flowers are 8–15 cm diameter, white, yellow, or purple; when white oryellow, the centre is still dark purple. The fruit is a capsule 2 cm diameter, containing severalseeds.UsesKenaf is cultivated for its fibre in India, Bangladesh, United States of America, Indonesia,Malaysia, South Africa, Viet Nam, Thailand, parts of Africa, and to a small extent in southeastEurope. The stems produce two types of fibre, a coarser fibre in the outer layer (bast fibre), anda finer fibre in the core. It matures in 100 to 200 days. Kenaf was grown in Egypt over 3000years ago. The kenaf leaves were consumed in human and animal diets, the bast fibre wasused for bags, cordage, and the sails for Egyptian boats. This crop was not introduced intosouthern Europe until the early 1900s. Today, principal farming areas are China, India, and it isalso grown in many other countries such as the US, Mexico and Senegal.The main uses of kenaf fibre have been rope, twine, coarse cloth (similar to that made fromjute), and paper. In California, Texas, Louisiana and Mississippi 3,200 acres (13 km²) of kenafwere grown in 1992, most of which was used for animal bedding and feed.Uses of kenaf fibre include engineered wood, insulation, clothing-grade cloth, soil-less pottingmixes, animal bedding, packing material, and material that absorbs oil and liquids. It is alsouseful as cut bast fibre for blending with resins for plastic composites, as a drilling fluid losspreventative for oil drilling muds, for a seeded hydromulch for erosion control.

Panasonic has set up a plant inMalaysia to manufacture kenaf fibre boards and export them to Japan.Kenaf seed oilKenaf seeds yield a vegetable oil that is edible with no toxins.[citation needed] The kenaf seedoil is also used for cosmetics, industrial lubricants and for biofuel production. Kenaf oil is high inomega polyunsaturated fatty acids (PUFAs) which are now known to help in keeping humanshealthy. Kenaf seed oil contains a high percentage of linoleic acid (Omega-6) a polyunsaturatedfatty acid (PUFA). Linoleic acid (C18:2) is the dominant PUFA, followed by oleic acid (C18:1).Alpha-linolenic acid (C18:3) is present in 2 to 4 percent. The PUFAs are essential fatty acids fornormal growth and health. Furthermore, they are important for reducing cholesterol and heartdiseases.Kenaf Seed oil is 20.4% of the total seed weight which is similar to cotton seed.[citation needed]Kenaf Edible Seed Oil Contains:Palmitic acid: 19.1%Oleic acid: 28.0% (Omega-9)Linoleic acid: 45% (Omega-6)Stearic acid: 3.0%Alpha-linolenic acid: 3% (Omega-3)Kenaf paperThe use of Kenaf in paper production offers various environmental advantages over producingpaper from trees. In 1960, the USDA surveyed more than 500 plants and selected kenaf as themost promising source of "tree-free" newsprint. In 1970, kenaf newsprint produced inInternational Paper Company’s mill in Pine Bluff, Arkansas, was successfully used by six U.S.newspapers. Printing and writing paper made from the fibrous kenaf plant has been offered inthe United States since 1992. Again in 1987, a Canadian mill produced 13 rolls of kenafnewsprint which were used by four U.S. newspapers to print experimental issues. They foundthat kenaf newsprint[2] made for stronger, brighter and cleaner pages than standard pine paperwith less detriment to the environment. Due partly to kenaf fibres being naturally whiter than treepulp, less bleaching is required to create a brighter sheet of paper. Hydrogen peroxide, anenvironmentally-safe bleaching agent that does not create dioxin, has been used with muchsuccess in the bleaching of kenaf.Various reports suggest that the energy requirements for producing pulp from kenaf are about20 percent less than those for wood pulp, mostly due to the lower lignin content of kenaf. Manyof the facilities that now process Southern pine for paper use can be converted to accommodatekenaf.[citation needed]An area of 1-acre (4,000 m2) of kenaf produces 5 to 8 tons of raw plant bast and core fibre in asingle growing season. In contrast, 1-acre (4,000 m2) of forest (in the US) producesapproximately 1.5 to 3.5 tons of usable fibre per year. It is estimated that growing kenaf on5,000 acres (20 km²) can produce enough pulp to supply a paper plant having a capacity of 200tons per day. Over 20 years, 1-acre (4,000 m2) of farmland can produce 10 to 20 times theamount of fiber that 1-acre (4,000 m2) of Southern pine can produce.[3]As one of the world’s important natural fibres, kenaf is covered by the International Year ofNatural Fibres 2009. 3/5

Results suggest H cannabinus leaves may have hematinic properties.• Phytochemicals / Fungitoxic Activity: Essential leaf oil characterized 58 components, amongthem: (E)-phytol, (Z)-phytol, n-nonanal, benzene acetaldehyde, (E)-2-hexenal and5-methylfurfural as major constituents. Oil had antifungal activity against Colletrotrichumfragariae, C gloeosporioides and C accutatum.• Antioxidant Activity: Study results suggest that the leaves of H cannabinus possesserythrocyte protective activity against drug induced (carbon-tetrachloride or paracetamol) 4/5

Results suggest that H cannabinus may be able to modulate macrophage-mediated responses. • Hepatoprotective: Aqueous leaf extract showed significant hepatoprotective activity against carbon tetrachloride and paracetamol induced damage evidenced by absence of necrosis in liver cells of pretreated rats. Inhibition of lipid peroxidation is suggested as a possible mechanism. Availability Wild-crafted. Cultivated. **** HORT.PURDUE.EDU… **** FLOWERSOFINDIA Blog this!
