Dryobalanops Aromatica
''Dryobalanops aromatica'', commonly known as Borneo camphor, camphor tree, Malay camphor, or Sumatran camphor, is a species of critically endangered plant in the family Dipterocarpaceae. The species name ''aromatica'' is derived from Latin (''aromaticus'' meaning spice-like) and refers to the smell of the dammar (resin). This species was one of the main sources of camphor and attracted early Arab traders to Borneo, at that time being worth more than gold, and used for incense and perfumes. It is found in Sumatra, peninsular Malaysia, and Borneo. It is a large emergent tree, up to 65 m or even 75 m tall, found in mixed dipterocarp forests on deep humic yellow sandy soils. It is a heavy hardwood sold under the trade names of Kapur. It is recorded from at least two protected areas ( Lambir and Gunung Mulu National Parks). Bergenin, malaysianol A, laevifonol, ampelopsin E, α-viniferin, ε-viniferin and diptoindonesin A can be isolated from the stem bark of ''D. aromatica''. ...

Forest Research Institute Malaysia
The Forest Research Institute Malaysia (FRIM; Malay: ''Institut Penyelidikan Perhutanan Malaysia'') is a statutory agency of the Government of Malaysia, under the Ministry of Land, Water and Natural Resources (KATS). FRIM promotes sustainable management and optimal use of forest resources in Malaysia by generating knowledge and technology through research, development and application in tropical forestry. FRIM is located in Kepong, near Kuala Lumpur. FRIM is the world's oldest and largest re-created tropical rain forest. History In 1926, the chief conservator of the forest (equivalent to today's director of forestry), G.E.S Cubitt, asked F.W. Foxworthy to establish a separate forest research unit for the Forestry Department. It was Foxworthy who selected the present site, at Kepong. He was also to become the institute's first chief research officer. The site comprised an area that was practically stripped of its original forest cover except for a few remnant trees at the ...

Lambir National Park
The Lambir Hills National Park ( ms, Taman Negara Bukit Lambir) is a national park in Miri Division, Sarawak, Malaysia, on the island of Borneo. It is a small park, at , and is composed largely of mixed dipterocarp forest, with some small areas of 'kerangas' (heath forest). The park is above sea level. Animal life Biologists have recorded 237 species of birds, 64 species of mammals, 46 species of reptiles and 20 species of frogs in the national park. Large mammals such as gibbons and sun bear are absent or very rare due to the small size of the forest and illegal hunting. More recent surveys (2003–2007), however, failed to find 20% of the park's resident bird species and 22% of the mammal species, losses that include half of the park's primate species and six out of seven hornbill species. Collapse in population of large mammals and birds is an ecological disaster in Lambir. The park's invertebrates include the Rajah Brooke's Birdwing butterfly (''Trogonoptera brookiana'') a ...

Trees Of Borneo
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dryobalanops
''Dryobalanops'' is a genus of flowering plants and the genus of family Dipterocarpaceae. The name ''Dryobalanops'' is derived from Greek (''dryas'' = a nymph associated with oaks and ''balanops'' = acorn) and describes the acorn-like nut. The genus has seven species, confined to the tropical forests of West Malesia (Sumatra, Peninsular Malaysia and Borneo). It is among the most abundant species of emergent trees in these forests, growing up to 80 m tall. The genus is of considerable importance as timber trees and sold under the trade name Kapur. The timber is an important heavy and durable construction timber. ''D. aromatica'' was an important source of camphor. As the trees mature, they mutually avoid touching each other in a phenomenon known as crown shyness. See also * Kapur (wood) Kapur (or Kapor) is a Dipterocarp timber classification, dipterocarp hardwood from trees of the genus ''Dryobalanops'' found in lowland tropical rainforests of Malaysia, Indonesia and Sou ...

Ampelopsin E
Ampelopsin, also known as dihydromyricetin and DHM, when purported as an effective ingredient in supplements and other tonics, is a flavanonol, a type of flavonoid. It is extracted from the Japanese raisin tree and found in '' Ampelopsis'' species ''japonica'', ''megalophylla'', and ''grossedentata''; ''Cercidiphyllum japonicum''; ''Hovenia dulcis''; '' Rhododendron cinnabarinum''; some ''Pinus'' species; and some ''Cedrus'' species, as well as in ''Salix sachalinensis''. ''Hovenia dulcis'' has been used in traditional Japanese, Chinese, and Korean medicines to treat fever, parasitic infection, as a laxative, and a treatment of liver diseases, and as a hangover treatment. Methods have been developed to extract ampelopsin on a larger scale, and laboratory research has been conducted with the compound to see if it might be useful as a drug in any of the conditions for which the parent plant has been traditionally used. Research Research suggests that DHM protects against DOX-i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
