fritillaria maximowiczii/抗菌的

Screening of antibacterial and antitumour activities of 33 different extracts prepared with three types of solvents (water, ethanol and methanol) was conducted. The extracts were obtained from 11 different plant species grown in Turkey: Eryngium campestre L., Alchemilla mollis (Buser) Rothm.,

To explore the resource of endophytic actinomycete in Fritillaria unibracteata, and alleviate the shortage of F. unibracteata resource, using F. unibracteata as experimental materials which growth in the western Sichuan plateau and cut its healthy bulb. Pure culture, insert, TLC and Oxford cup were

Infection by Helicobacter pylori has been ascertained to be an important etiologic impetus leading usually to chronic active gastritis and gastric ulcer with growing incidences worldwide. Utilizing as the test pathogen a standard and five clinic strains of Helicobacter pylori, the antibacterial

A glucosylsterol, beta-sitosterol-3-O-glucopyranoside, has been isolated as an active principle with sortase inhibitory effect from the bulbs of Fritillaria verticillata by bioassay-guided chromatographic fractionation. The isolate was a potent inhibitor of sortase, with an IC(50) value of 18.3

Inhibition by medicinal plant extracts of a recombinant sortase was evaluated for antibacterial drug discovery. The coding region of sortase, a transpeptidase that cleaves surface proteins of gram-positive bacteria, was amplified by PCR from the chromosome of Staphylococcus aureus ATCC 6538p with

The endophytic fungus Cladosporium sphaerospermum WBS017 was obtained from healthy bulbs of Fritillaria unibracteata var. wabuensis. Fermentation of C. sphaerospermum on solid rice medium yielded three new hybrid polyketides, cladosins L-N (1-3), and a known derivative cladodionen (4). Further
