Acrocarpus Fraxinifolius PORTABLE
Acrocarpus is a genus of trees in the legume family, Fabaceae. It comprises one species, Acrocarpus fraxinifolius, the pink cedar, a large deciduous emergent tree native to Bangladesh, Bhutan, China, India, Indonesia, Laos, Myanmar, Nepal and Thailand. Its also known as Balangi or Kurungatti in India.
Local names: Bengali (mundani), Burmese (mayahnin,yetama), English (shingle tree,pink cedar,Indian ash,Kenya coffee shade,Australian ash), French (kuranjan), Hindi (belanji,hevulige,kuranjan,malankommao,silchhal), Indonesian (madang pariek,delimas), Javanese (delimasAcrocarpus fraxinifolius is a stately deciduous tree, attaining heights of 30-60 m; stem cylindrical, free of branches for up to 75% of its total height. Even above its massive plank buttresses, it can achieve a diameter of over 200 cm. The branches remain relatively thin and are horizontally deployed. Bark is thin and light grey in colour. Although a legume, it apparently does not have nitrogen-fixing nodules. A. fraxinifolius is deep rooting, sometimes upto 4.5 m into the soil.Leaves bipinnate, about 30 cm with 3-4 compound leaflets and consisting of 5-6 elliptical, lanceolate leaflets 7-10 cm long and arranged in pairs; bright red when young, giving the tree its characteristic appearance.Flowers appear on tree when leafless, up to 20 dense heads hanging down from branch ends, each 12 cm long, dripping nectar from the reddish-green to orange flowers.Fruit an elongated and flattened pod, long-stipitate, narrowly winged; (min. 3) 10-18 seeded. Seed slightly lens shaped, brown.
EcologyA. fraxinifolius grows best in submontane areas in the humid and subhumid tropics with a short, dry spell. It is very sensitive to frost. In Thailand, it occurs in evergreen gallery forest and is more frequent in India and Myanmar. Regenerates primarily in small, burnt areas, on open patches where fresh soil has been exposed and along newly constructed roads. A. fraxinifolius is a pioneer and demands light, but it can tolerate slight shade when young. It is most suitable for moderate altitudes with red soil and a moist climate.
Tree managementIn India, to ensure sufficient natural regeneration of this light-demanding species, the forest floor is cleared of weeds and raked, after which the canopy is gradually removed as young trees become established. Frequent tending is required until the crowns of the young trees close. Periodic weeding is required until they are well into their sapling stage; the 1st thinning should be performed 3-4 years after planting. As the tree requires a large crown for optimal growth, regular thinning is necessary until the stand is fully developed. On favourable sites, a mean annual increment of 10 cubic m/ha may be expected. In Malawi, 2-year-old trees yielded 33 t/ha of total aboveground biomass. A. fraxinifolius coppices vigorously. Rotation period for fuel is 8-10 years and for timber 30-40 years. The tree should not be planted near houses as dry branches drop off. Competes with crops if grown in fields.

A. fraxinifolius is propagated by seed; the use of wildings has been reported in India. Patch budding has been used and 80% success recorded during establishment seed orchards. Seed should be pretreated with sulphuric acid for 10 min, or with hot water and left to soak for 24 hours before being sown in a shaded bed. A germination of 80-95% within only 2-7 days is achieved after this pretreatment. Under natural conditions, some seeds may germinate within a week, while others may lie dormant for a year before germinating. Seedlings are ready for planting out when 3 months old and 30-45 cm tall. The seedlings are pricked out into beds or containers and placed in full sunlight. From the beds they can be planted bare-rooted or as stumps or striplings.
Acrocarpus fraxinifolius - Pink Cedar or Shingle Tree, is a large deciduous emergent tree that can reach 60m in the right conditions. Older trees have massive plank buttresses and the stem, light grey and thinly barked, can be over 75% free of branches. Thin horizontal branches. Bi-pinnate leaves with 3-4 compound leaves with 5-6 elliptical, lanceolate leaflets up to 10 cm long and bright red when young. Red-Orange, Pale Green flowers appear on tree when leafless. Fruit is an elongated and flattened pod, long-stipitate, and narrowly winged. Acrocarpus fraxinifolius has very deep roots up to 4.5m. Commonly grown throughout the tropics in plantations for its wood especially in badly degraded areas which are not protected from cattle grazing. It?s used as shade trees in the coffee plantations in India. The timber is recommended for making furniture and cabinets/tea boxes. Acrocarpus fraxinifolius has been identified as one of the food plant for the endangered lion tailed macaque during the period of fruit scarcity.
Acrocarpus fraxinifolius grows best in submontane areas in the humid and subhumid tropics with a short, dry spell[303 ]. It succeeds at elevations from sea level to about 2,000 metres, growing best in areas where the annual precipitation is between 500 - 3,000 mm and the temperature ranges between 15 - 26c[303 ]. Plants are very sensitive to frost[303 ]. Prefers a fertile soil and a position in full sun, though it can tolerate a small amount of shade, especially when young[200 , 303 , 307 ]. Succeeds in acid and alkaline soils[303 ]. A pioneer species, it regenerates primarily in small, burnt areas, on open patches where fresh soil has been exposed and along newly constructed roads[303 ]. Shingle tree is quite fast-growing, able to reach heights of up to 3 metres within 12 months from seed[307 ]. Growth of older trees is still rapid, as observed in Tanzania where the mean annual increment of 13 year old trees was 120cm in height and 19mm in diameter. In Rwanda the mean height of trees was 150cm after 1 year, 4.4 metres after 2 years, 6.7 metres after 3 years, and 19 metres after 24 years with a bole diameter of 35cm[299 ]. A deep rooting plant, the roots can penetrate up to 4.5 metres into the soil[303 ]. It coppices vigorously, the rotation period for fuel is 8 - 10 years and for timber 30 - 40 years[303 ]. The tree competes with crops if grown in fields[303 ]. Young plants have been observed to behave as climbers and stranglers of other trees[307 ]. The tree is a good source of nectar and a good bee forage[303 ]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[200 ]."
Purpose: Liver fibrosis is considered as one of the ultimate outcomes of chronic liver disorders, characterized by outrageous cell proliferation and abnormal deposition of extracellular matrix, resulting in sever pathological distortions in the architecture and performance of liver tissues. The present study aimed to investigate the protective properties of aqueous methanol extract of Acrocarpus fraxinifolius leaves (AFL) against liver fibrosis induced by dual toxicity of γ-irradiation and carbon tetrachloride (CCl4) in rats.
