Robinose is a disaccharide composed of 6″-O-α-rhamnopyranosyl-β-galactopyranoside. The sugar can be found in Acalypha hispida . [1]

Disaccharide complex sugars, the sugar formed when two monosaccharides (simple sugars) are joined by glycosidic linkage; soluble in water; one of the four chemical groupings of carbohydrates

A disaccharide is the sugar formed when two monosaccharides are joined by glycosidic linkage. Like monosaccharides, disaccharides are soluble in water. Three common examples are sucrose, lactose, and maltose.

Rhamnose is a naturally occurring deoxy sugar. It can be classified as either a methyl-pentose or a 6-deoxy-hexose. Rhamnose occurs in nature in its L-form as L-rhamnose (6-deoxy-L-mannose). This is unusual, since most of the naturally occurring sugars are in D-form. Exceptions are the methyl pentoses L-fucose and L-rhamnose and the pentose L-arabinose.

Galactose A monosaccharide sugar

Galactose, sometimes abbreviated Gal, is a monosaccharide sugar that is about as sweet as glucose, and about 30% as sweet as sucrose. It is a C-4 epimer of glucose.

Robinin is a kaempferol-3-O-robinoside-7-O-rhamnoside.

Robinin is a chemical compound. It can be isolated from Vinca erecta or from the common locust Robinia pseudoacacia. It is a flavone glycoside based on kaempferol.

Kaempferol chemical compound

Kaempferol (3,4′,5,7-tetrahydroxyflavone) is a natural flavonol, a type of flavonoid, found in a variety of plants and plant-derived foods. Kaempferol is a yellow crystalline solid with a melting point of 276–278 °C (529–532 °F). It is slightly soluble in water and highly soluble in hot ethanol, ethers, and DMSO. Kaempferol acts as an antioxidant by reducing oxidative stress. Many studies suggest that consuming kaempferol may reduce the risk of various cancers, and it is currently under consideration as a possible cancer treatment. It is named for 17th-century German naturalist Engelbert Kaempfer.

Ringed seal species of mammal

The ringed seal, also known as the jar seal, as netsik or nattiq by the Inuit and as Ньиэрпэ by the Yakut, is an earless seal inhabiting the Arctic and sub-Arctic regions. The ringed seal is a relatively small seal, rarely greater than 1.5 m in length, with a distinctive patterning of dark spots surrounded by light grey rings, hence its common name. It is the most abundant and wide-ranging ice seal in the Northern Hemisphere: ranging throughout the Arctic Ocean, into the Bering Sea and Okhotsk Sea as far south as the northern coast of Japan in the Pacific, and throughout the North Atlantic coasts of Greenland and Scandinavia as far south as Newfoundland, and include two freshwater subspecies in northern Europe. Ringed seals are one of the primary prey of polar bears and killer whales, and have long been a component of the diet of indigenous people of the Arctic.

Acalypha is a genus of flowering plants in the family Euphorbiaceae. It is the sole genus of the subtribe Acalyphinae. It is one of the largest euphorb genera, with approximately 450 to 462 species. The genus name Acalypha is from the Ancient Greek ἀκαλύφη (akalúphē) ("nettle"), an alternative form of ἀκαλήφη (akalḗphē), and was inspired by the nettle-like leaves. General common names include copperleaf and three-seeded mercury. Native North American species are generally inconspicuous most of the year until the fall when their stems and foliage turn a distinctive coppery-red.

Acalypha hispida, the chenille plant, is a flowering shrub which belongs to the family Euphorbiaceae, the subfamily Acalyphinae, and the genus Acalypha. Acalypha is the fourth largest genus of the Euphorbiaceae family, and contains many plants native to Hawaii and Oceania. This plant is also known as the Philippines Medusa, red hot cat's tail and fox tail in English, pokok ekor kucing in Malay, Rabo de Gato in Portuguese, Tai tượng đuôi chồn in Vietnamese, poochavaal in Malayalam and shibjhul in Bengali. Acalypha hispida is cultivated as a house plant because of its attractiveness and brilliantly colored, furry flowers.

<i>Acalypha rubrinervis</i> species of plant

Acalypha rubrinervis is an extinct plant in the spurge family (Euphorbiaceae), from the island of Saint Helena in the South Atlantic Ocean. It was called string tree on account of the thin pendulous inflorescences which resembled red strings. Disturbance following human settlement on the island destroyed its habitat and it was last seen in the 19th century. It is thus one of a number of island plants to have been driven to extinction by human activity.

The flowering shrub Acalypha californica is known as the California copperleaf, and sometimes by the older name Pringle three-seeded mercury. It is the only Acalypha species native to California, where it is most abundant in the hills of San Diego County. It is a member of the chaparral plant community.

<i>Angophora hispida</i> species of plant

Angophora hispida grows as a mallee, or as a tree to about 7 m (25 ft) in height. A. hispida's small size, especially when compared to its Angophora and Eucalyptus relatives, leads to it being known by the common name dwarf apple. It is native to a relatively small patch of central New South Wales – from just south of Sydney up to the Gosford area. The plant's leaves are sessile (stalk-less) and hug the stem with heart-shaped bases. Its previous name – A. cordifolia – referred to these cordate leaves. Another distinctive feature are the red bristly hairs that cover the branchlets, flower bases and new growth. This leads to the specific epithet hispida.
