Mallotojaponin B is a dimeric phlorogucinol found in Mallotus oppositifolius .

Mallotus oppositifolius is a plant species in the genus Mallotus found in Africa and Madagascar.

The bioassay-guided fractionation of an ethanol extract of the leaves and inflorescence of M. oppositifolius collected in Madagascar led to the isolation of the two new bioactive dimeric phloroglucinols mallotojaponins B and C, together with mallotophenone. These compounds show antiproliferative and antiplasmodial activities. [1]

<i>Mallotus</i> (plant) genus of plants

Mallotus is a genus of the spurge family Euphorbiaceae first described as a genus in 1790. Two species are found in tropical Africa and Madagascar. All the other species are found in East Asia, the Indian Subcontinent, Southeast Asia, eastern Australia, and certain islands of the western Pacific.

Phloroglucinol chemical compound

Phloroglucinol is an organic compound with the formula C6H3(OH)3. It is a colorless solid. It is used in the synthesis of pharmaceuticals and explosives. Phloroglucinol is one of three isomeric benzenetriols. The other two isomers are hydroxyquinol (1,2,4-benzenetriol) and pyrogallol (1,2,3-benzenetriol). Phloroglucinol, and its benzenetriol isomers, are still defined as "phenols" according to the IUPAC official nomenclature rules of chemical compounds. Many such monophenolics are often termed "polyphenols" by the cosmetic and parapharmaceutical industries, but they cannot be by any scientifically-accepted definition.

<i>Claoxylon</i> genus of plants

Claoxylon is a flowering plant genus in the spurge family, Euphorbiaceae, comprising dioecious subshrubs to small trees. It was first described as a genus in 1824. The genus is distributed in paleotropical areas: Madagascar through South and Southeast Asia, Malesia to Melanesia, Hawaiʻi, and Australia. Half of the species are in Malesia. According to a molecular phylogenetic study by Wurdack, Hoffmann & Chase (2005), Claoxylon is sister to Erythrococca, and together they form the top of a Hennigian comb-like phylogeny.

<i>Diospyros melanoxylon</i> species of plant

Diospyros melanoxylon, the Coromandel ebony or East Indian ebony, is a species of flowering tree in the family Ebenaceae native to India and Sri Lanka; it has a hard, dry bark. Its common name derives from Coromandel, the coast of southeastern India. Locally it is known as temburini or by its Hindi name tendu. In Odisha, Jharkhand, and Assam, it is known as kendu. The leaves can be wrapped around tobacco to create the Indian beedi, which has outsold conventional cigarettes in India.

Conessine chemical compound

Conessine is a steroid alkaloid found in a number of plant species from the family Apocynaceae, including Holarrhena floribunda, Holarrhena antidysenterica and Funtumia elastica. It acts as a histamine antagonist, selective for the H3 subtype (with an affinity of pKi = 8.27; Ki = ~5 nM). It was also found to have long CNS clearance times, high blood-brain barrier penetration and high affinity for the adrenergic receptors.

Small nucleolar RNA sR8

Small nucleolar RNA sR8 is a non-coding RNA belonging to the C/D box class of snoRNAs. sR8, along with other C/D box snoRNAs, performs 2′-O-methylation of ribose on a target strand of ribosomal RNA. Targeting is achieved through the C and D box components, which are short sections of conserved sequences, as well as C'/D' boxes. These sequences base-pair with nucleotides in the target rRNA to direct their methylation.

Dehydrated tergallic-C-glucoside can be found in the cork from Quercus suber.
