Resveratrol (3,5,4′-trihydroxy-trans-stilbene) is a stilbenoid, a type of natural phenol, and a phytoalexin produced by several plants in response to injury or when the plant is under attack by pathogens, such as bacteria or fungi. Sources of resveratrol in food include the skin of grapes, blueberries, raspberries, mulberries, and peanuts.

<i>Banksia robur</i> Species of shrub in the family Proteaceae from the east coast of Australia

Banksia robur, commonly known as swamp banksia, grows in sand or peaty sand in coastal areas from Cooktown in north Queensland to the Illawarra region on the New South Wales south coast. It is often found in areas which are seasonally inundated.

<i>Banksia oblongifolia</i> Species of plant

Banksia oblongifolia, commonly known as the fern-leaved, dwarf or rusty banksia, is a species in the plant genus Banksia. Found along the eastern coast of Australia from Wollongong, New South Wales in the south to Rockhampton, Queensland in the north, it generally grows in sandy soils in heath, open forest or swamp margins and wet areas. A many-stemmed shrub up to 3 m (9.8 ft) high, it has leathery serrated leaves and rusty-coloured new growth. The yellow flower spikes, known as inflorescences, most commonly appear in autumn and early winter. Up to 80 follicles, or seed pods, develop on the spikes after flowering. Banksia oblongifolia resprouts from its woody lignotuber after bushfires, and the seed pods open and release seed when burnt, the seed germinating and growing on burnt ground. Some plants grow between fires from seed shed spontaneously.

<i>Banksia paludosa</i> Shrub in the family Proteaceae native to New South Wales, Australia

Banksia paludosa, commonly known as the marsh or swamp banksia, is a species of shrub in the plant genus Banksia. It is native to New South Wales, Australia, where it is found between Sydney and Batemans Bay, with an isolated population further south around Eden. There are two recognised subspecies, the nominate of which is a spreading shrub to 1.5 m (4.9 ft) in height, and subsp. astrolux is a taller shrub to 5 m (16 ft) high found only in Nattai National Park.

<i>Banksia plagiocarpa</i> Species of shrub in the family Proteaceae native to Queensland

Banksia plagiocarpa, commonly known as Dallachy's blue banksia, blue banksia or Hichinbrook banksia, is a species of shrub or tree in the plant genus Banksia. It occurs only on Hinchinbrook Island, Queensland and the immediately adjacent mainland. First collected in 1867, Banksia plagiocarpa was not described until 1981, when Alex George named it in his monograph of the genus Banksia. Genetic studies show it to be related to Banksia aquilonia, Banksia oblongifolia and Banksia robur.

<i>Dryobalanops aromatica</i> Species of tree

Dryobalanops aromatica, commonly known as Borneo camphor, camphor tree, Malay camphor, or Sumatran camphor, is a species of 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.

Dryobalanops oblongifolia is a species of plant in the family Dipterocarpaceae, native to regions of Southeast Asia and Maritime Southeast Asia.

<i>Breynia oblongifolia</i> Species of flowering plant

Breynia oblongifolia, commonly known as coffee bush, grows naturally in Australia and New Guinea as shrubs up to 3 m (10 ft) in height. The species produces alternate, distichous, ovate leaves 20–30 mm (0.8–1.2 in) long by 10–20 mm (0.4–0.8 in) wide. Small, green flowers are produced in spring and summer, and these are followed by orange or pink berries about 6 mm (0.24 in) diameter that turn black when fully ripe.

ε-Viniferin Chemical compound

ε-Viniferin is a naturally occurring phenol, belonging to the stilbenoids family. It is a resveratrol dimer.

α-Viniferin Chemical compound

α-Viniferin is a stilbene trimer. It can be isolated from Caragana chamlagu and from Caragana sinica and from the stem bark of Dryobalanops aromatica. It is also present in relation to resistance to Botrytis cinerea and Plasmopara viticola in Vitis vinifera and Vitis riparia. It has been shown to inhibit acetylcholinesterase.

<span class="mw-page-title-main">Crown shyness</span> Phenomenon in which the crowns of fully stocked trees do not touch each other

Crown shyness is a feature observed in some tree species, in which the crowns of fully stocked trees do not touch each other, instead forming a canopy with channel-like gaps. This is most prevalent among trees of the same species, but also occurs between trees of different species. There exist many hypotheses as to why crown shyness is an adaptive behavior, and research suggests that it might inhibit spread of leaf-eating insect larvae.

Binsuluk Forest Reserve is a protected forest reserve on the Klias Peninsula, in Beaufort District of Interior Division, Sabah, Malaysia.
