Shorea seminis is a species of tree in the family Dipterocarpaceae. It is native to Borneo and Palawan. [1]
Diptoindonesin A is a C-glucoside of ε-viniferin isolated from S. seminis. [2]
Dipterocarpaceae is a family of 16 genera and about 695 known species of mainly tropical lowland rainforest trees. The family name, from the type genus Dipterocarpus, is derived from Greek and refers to the two-winged fruit. The largest genera are Shorea, Hopea, Dipterocarpus, and Vatica. Many are large forest-emergent species, typically reaching heights of 40–70 m, some even over 80 m, with the tallest known living specimen 93.0 m tall. The species of this family are of major importance in the timber trade. Their distribution is pantropical, from northern South America to Africa, the Seychelles, India, Indochina, Indonesia, Malaysia and Philippines. The greatest diversity of Dipterocarpaceae occurs in Borneo. Some species are now endangered as a result of overcutting, extensive illegal logging, and habitat conversion. They provide valuable woods, aromatic essential oils, balsam, and resins, and are a source for plywood.
Shorea is a genus of about 196 species of mainly rainforest trees in the family Dipterocarpaceae. The genus is named after Sir John Shore, the governor-general of the British East India Company, 1793–1798. The timber of trees of the genus is sold under the common names lauan, luan, lawaan, meranti, seraya, balau, bangkirai, and Philippine mahogany.
Shorea teysmanniana is a timber tree of the family Dipterocarpaceae. It occurs in Sumatra, Peninsular Malaysia and Borneo.
Shorea almon is a species of plant in the family Dipterocarpaceae. It is native to Borneo and the Philippines.
Shorea bentongensis is a species of tree in the family Dipterocarpaceae. It is endemic to Peninsular Malaysia, where it is threatened by habitat loss.
Shorea bracteolata is a species of plant in the family Dipterocarpaceae. The species name bracteolata is derived from Latin and refers to the persistent bracteoles of the inflorescence.
Shorea ciliata is a species of plant in the family Dipterocarpaceae. It is a tree found in Peninsular Malaysia.
Shorea collina is a species of tree in the family Dipterocarpaceae. It grows naturally in Peninsular Malaysia.
Shorea kudatensis is a species of tree in the family Dipterocarpaceae. It is endemic to Borneo, in low coastal hills of the north and west of Malaysian Sabah.
Shorea longiflora is a species of tropical lowland rainforest tree in the family Dipterocarpaceae. It is endemic to Borneo.
Shorea lumutensis is a species of tree in the family Dipterocarpaceae. It is endemic to Peninsular Malaysia.
Shorea ochrophloia is a species of plant in the family Dipterocarpaceae. It is native Sumatra and Peninsular Malaysia.
Shorea roxburghii is a species of tree in the family Dipterocarpaceae. It is native to Cambodia, India, Laos, Malaysia, Burma, Thailand, and Vietnam.
Shorea smithiana is a large emergent rainforest tree species in the Dipterocarpaceae. Shorea smithiana is endemic to Borneo. It is threatened by habitat loss. The tallest measured specimen is 82.3 m tall in the Tawau Hills National Park, in Sabah, Borneo.
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 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.
ε-Viniferin is a naturally occurring phenol, belonging to the stilbenoids family. It is a resveratrol dimer.
Diptoindonesin A is a C-glucoside of ε-viniferin isolated from the two Dipterocarpaceae Shorea seminis and Dryobalanops aromatica.
Astringin is a stilbenoid, the 3-β-D-glucoside of piceatannol. It can be found in the bark of Picea sitchensis or Picea abies.
δ-Viniferin is a resveratrol dehydrodimer. It is an isomer of epsilon-viniferin. It can be isolated from stressed grapevine leaves. It is also found in plant cell cultures and wine. It can also be found in Rheum maximowiczii.
Oligostilbenoids are oligomeric forms of stilbenoids. Some molecules are large enough to be considered polyphenols and constitute a class of tannins.
