Quercetin 3,7,3′-trisulphate from Flaveria bidentis

Phytochemistry, 1985
Abstract From leaves of Flaveria bidentis a new quercetin trisulphate was isolated and characterized as quercetin 3,7,3′-trisulphate by means of spectroscopic (UV, 1 H NMR, 13 C NMR) and chemical methods.

The roles of malate and aspartate in C4 photosynthetic metabolism of Flaveria bidentis (L.)

Planta, 1996
In C4 grasses belonging to the NADP-malic enzyme-type subgroup, malate is considered to be the predominant C4 acid metabolized during C4 photosynthesis, and the bundle sheath cell chloroplasts contain very little photosystem-II (PSII) activity. The present studies showed that Flaveria bidentis (L.), an NADP-malic enzyme-type C4 dicotyledon, had ...

The use of quercetin sulphates from Flaveria bidentis as inhibitors of the enzymic reduction of carbonyl groups

Phytochemistry, 1986
Abstract Quercetin tetrasulphate and quercetin acetyl trisulphate from Flaveria bidentis are non-competitive inhibitors of the reduction of carbonyl groups catalysed by alcohol, lactic and malic dehydrogenases with K i / K m values of 3 × 10 −3 to 2.0.

Molecular and biochemical characterization of two nucleoside diphosphate kinase cDNA clones fromFlaveria bidentis

Genome, 1996
Two nucleoside diphosphate kinase cDNA clones have been isolated from Flaveria bidentis by immunoscreening of an expression library with a polyclonal antibody raised against Flaveria chloraefolia flavonol 3-sulfotransferase (F3-ST). The clones represent members of a small multigene family in this species. The nucleotide sequences of the two cDNA clones

[Effects of Flaveria bidentis invasion on the diversity of functional bacteria in rhizosphere soil.]

Ying yong sheng tai xue bao = The journal of applied ecology, 2018
Flaveria bidentis is an invasive plant found in large areas of northern China. This study conducted a separation and screening of the main functional bacteria in the soil of F. bidentis and investigated the change in the community structure. A variety of functional microbes were isolated using selective media and rep-PCR clustering, and a diversity ...

[Potential distribution areas of alien invasive plant Flaveria bidentis (Asteraceae) in China].

Ying yong sheng tai xue bao = The journal of applied ecology, 2010
Flaveria bidentis (Asteraceae), a potential exotic invasive weed to agro-ecosystem and rangeland ecosystem, has recently invaded Tianjin City and Hebei Province (Hengshui and Langfang) in North China, and is spreading further. Based on its current geographical distribution in the world, the potential distribution areas of this weed in China were ...

[Prediction of potential suitable distribution area of Flaveria bidentis in China based on niche models].

Ying yong sheng tai xue bao = The journal of applied ecology, 2012
Based on the distribution records of Flaveria bidentis in China, and by using five ecological niche models (GARP, Maxent, ENFA, Bioclim, and Domain), 32 eco-geographical variables were chosen to simulate the potential suitable distribution area of F.
