Two pyridine alkaloids were isolated from the derubberized resin of the hybrid Parthenium argentatum x P tomentosa. These alkaloids are (+/-)-N-[4-(1-aminoethyl) phenyl]-4-[3-methylbutenylidine]-1,4-dihydropyridine (guayulamine A) and (+/-)-N-[4-(1-aminoethyl) phenyl]-4-[4-methylpentenylidine]-1, 4-dihydropyridine (guayulamine B). The structures were established by one- and two-dimensional NMR ...
Scutopalus tomentosus sp. nov. is described and illustrated from Plantago tomentosa Lam. (Plantaginaceae) in a vineyard agroecosystem at Dois Lajeados county, State of Rio Grande do Sul, Brazil. This is the first species of this genus described from the Americas. A key to world species is included.
Two new 27-nor-triterpene glycosides, tomentosides A (1) and B (2), were isolated from Peruvian "Uña de Gato" (cat's claw, plant of origin: Uncaria tomentosa), a traditional herbal medicine in Peru. Their structures were determined by spectroscopic analysis and chemical interconversions. This is the first report of naturally occurring pyroquinovic acid glycosides.
Gluconobacter thailandicus strain NBRC 3257, isolated from downy cherry (Prunus tomentosa), is a strict aerobic rod-shaped Gram-negative bacterium. Here, we report the features of this organism, together with the draft genome sequence and annotation. The draft genome sequence is composed of 107 contigs for 3,446,046 bp with 56.17% G+C content and contains 3,360 protein-coding genes and 54 RNA g...
The diuretic activity of concentrated ethanolic extract of Aerva lanata (Linn) & Aerva tomentosa Forsk on healthy albino rats were studied with frusemide as reference drug. The urine output increased with concentrated ethanolic extract of Aerva lanata only. In this case the level of electrolytes in urine also increased. But the diuretic activity was mild as compared to frusemide.
Populus tomentosa is an economically important tree crop that produces wood for lumber, pulp, paper, and biofuels. Wood quality traits are likely to be strongly affected by the plant hormone gibberellic acid (GA), which regulates growth. GA20Ox encodes one of the major regulatory enzymes of GA biosynthesis and may therefore play a large role in growth and wood quality. Here, linkage disequilibr...
Thirteen pregnane glycosides were isolated from fresh leaves of Marsdenia tomentosa collected in the Fukuyama district. Of these, six were glycosides previously obtained from the same plant collected in the Fukuoka district and one from another Asclepiadaceous plant. The structures of the six new glycosides were determined by spectrometric method.
Draft Genome Sequence of the Growth-Promoting Endophyte Paenibacillus sp. P22, Isolated from Populus
Paenibacillus sp. P22 is a Gram-negative facultative anaerobic endospore-forming bacterium isolated from poplar hybrid 741 (♀[Populus alba × (P. davidiana + P. simonii) × P. tomentosa]). This bacterium shows strong similarities to Paenibacillus humicus, and important growth-promoting effects on in vitro grown explants of poplar hybrid 741 have been described.
