Ancistrocladaceae - Wikipedia, the free encyclopedia Ancistrocladaceae is the botanical name for a family of flowering plants. This family Ancistrocladaceae would belong to this same clade, although the plants in the family are non-carnivorous. Ancistrocladaceae in L. Watson and M.J. Dallwitz (1992 onwards). en.wikipedia.org /wiki/Ancistrocladaceae   (225 words)

Both plant families, the Ancistrocladaceae and the Dioncophyllaceae, have in common that they are the only known 'producers' of the naphthylisoquinoline alkaloids, structurally, biosynthetically, and pharmaceutically unique natural biaryl products (see also 'Naphthylisoquinoline Alkaloids'). www-organik.chemie.uni-wuerzburg.de /ak_bring/research-garden.html   (1078 words)

GENTRYMINE B The Gentrymines were isolated from a sample of Ancistrocladus korupensis D. Thomas and Gereau (Ancistrocladaceae), a newly described species of liana originally collected in the region of Korup National Park in Cameroon in 1987 (Thomas 6889). They are named in honor of the late Alwyn H. Gentry, one of the leading authorities in tropical botany, who died in an airplane crash in western Ecuador on August 3, 1993. Gentrymine B is the first quaternary naphthyl tetrahydroisoquinoline alkaloid found in the families Ancistrocladaceae and Dioncophyllaceae. www.wlbcenter.org /discovery_7.htm   (126 words)

Institute of Plant Biochemistry Halle (Saale) - Germany However, the carbon skeleton of isoquinoline alkaloids found in species of the Ancistrocladaceae and Dioncophyllaceae originates from acetate rather than from L-tyrosine. Naphthylisoquinoline alkaloids in the liana Triphyophyllum peltatum (Dioncophyllaceae) are derived from acetate. Biosynthetically related compounds, acetate-derived naphthoquinones, occur not only in the Ancistrocladaceae and Dioncophyllaceae but also in several taxonomically related families, e.g. www.ipb-halle.de /dfg/dfg-spp-1152/homepage/kutchan.htm   (316 words)

Ancistrocladi   (Site not responding. Last check: 2007-10-31) Ancistrocladus (Ancistrocladaceae) is the only genus of a small family of plants occurring in several regions of the palaeotropis. Especially interesting is the fact that both genetical and phytochemical data define a larger group of interrelated families, viz. Droseraceae, Drosophyllaceae, Dioncophyllaceae, Ancistrocladaceae, Nepenthaceae, Plumbaginaceae, and Polygonaceae, all of which containing the naphthoquinone plumbagin or biosynthetically related anthraquinones (at least in some, frequently the more "primitive" members of each family). aaa-proteins.uni-graz.at /Ancistrocladi.html   (187 words)

Institute of Plant Biochemistry Halle (Saale) - Germany The naphthylisoquinoline alkaloid dioncophylline A, however, the most prominent representative of this new class of intriguing secondary metabolites from tropical Ancistrocladaceae and Dioncophyllaceae plants, originates from acetate units, exclusively. We have shown that both molecular halves, the isoquinoline part and the naphthalene portion, are formed from identical polyketide precursors.

Drosophyllum - Wikipedia, the free encyclopedia The genus had always been assumed to be closely allied to Drosera and was previously placed in the Droseraceae. Recent molecular and biochemical studies, however, place it in the monotypic Drosophyllaceae (Chrtek, Slaviková and Studnicka), as recommended by the Angiosperm Phylogeny Group, and allied with the Dioncophyllaceae (Triphyophyllum) and Ancistrocladaceae.

CPN Samples Another even more striking result is the grouping of Droseraceae, Drosophyllaceae (the separation of Drosophyllum from Droseraceae is also supported by DNA analysis), Dioncophyllaceae, Ancistrocladaceae, Nepenthaceae, Plumbaginaceae, Polygonaceae, and Simmondsiaceae together in one clade to which the couple Tamaricaceae/Frankeniaceae is the closest sister clade (see Figure 1). An examination of Ancistrocladaceae (consisting only of the small palaeotropical genus Ancistrocladus which is known for some time to be the closest relative of Dioncophyllaceae, sharing e.g. Nevertheless, there are some apparently bridging features to Nepenthaceae (which overlap in some parts of the distributional range with Ancistrocladaceae), viz. www.carnivorousplants.org /cpn/samples/Science262Evol.htm   (1585 words)

NIH Office of Technology Transfer (OTT) >> Abstract Search This invention provides new napthylisoquinoline alkaloid compounds, and compositions and methods of use of known and new napthylisoquinoline alkaloids, for treatment or prevention of malaria. Some compounds of this class occur naturally in plant species of the Ancistrocladaceae and Dioncophyllaceae plant families which are found in tropical Africa and southern and southeast Asia. The compounds exhibit effective antimalarial properties and offer important new weapons in the treatment of this devastating disease. ott.od.nih.gov /db/abstxt.asp?refno=157   (141 words)

non-core Caryophyllales   (Site not responding.

Analyses of matK sequences alone for several species of Nepenthes, Drosera, and Ancistrocladus, plus Drosophyllum and all three genera of Dioncophyllaceae, resulted in a well-supported tree with Droseraceae sister to a clade of Nepenthaceae + (Drosophyllum + (Dioncophyllaceae + Ancistrocladaceae)) (Meimberg et al.

Triphyophyllum, this syndrome was lost in the taxa of Dioncophyllaceae and Ancistrocladaceae.
