Are Seedlings of Hemerocallis Fulva Specially Variable?

Steroidal saponins from Hemerocallis fulva var. kwanso.

Two steroidal saponins, hemeroside A and B, were isolated from the aerial part of Hemerocallis fulva var. kwanso for the first time. The structures of these compounds were established as 24S-hydroxy-neotokorogenin 1-O-alpha-L-arabinopyranosyl 24-O-beta-D-glucopyranoside (1) and isorhodeasapogenin 3-O-beta-D-glucopyranosyl-(1-->3)-[beta-D-xylopyranosyl-(1-->2)]-beta-D-glucopyranosyl-(1-->4)-beta...

N-glycosides of amino acid amides from Hemerocallis fulva var. sempervirens.

As part of our search for sedative substances from natural sources, we isolated two novel amino acid amides connected with the fructopyranose, kwansonine A (1) and kwansonine B (2), together with three known amino acid amides, longitubanine A (3), longitubanine B (4), and pinnatanine (5), from Hemerocallis fulva L. var. sempervirens (ARAKI) M. HOTTA. The structures of 1 and 2 have been determin...

Polymicrobial ventriculitis involving Pseudomonas fulva.

Infections due to Pseudomonas fulva remain a rare but emerging concern. A case of ventriculitis due to Enterobacter cloacae and Pseudomonas fulva following placement of an external ventricular drain is described. Similar to other reports, the organism was initially misidentified as Pseudomonas putida. The infection was successfully treated with levofloxacin.

Insecticides for Suppression of Nylanderia fulva

Pest control operators and homeowners are challenged to manage pest populations below acceptable thresholds. Contact and bait insecticides are key components of an Integrated Pest Management (IPM) strategy, however, little is known about their efficacy. In repellency and efficacy bioassays, N. fulva...
