Biological control agent of common scab disease by antagonistic strain Bacillus sp. sunhua
TLDR
An antagonistic strain against Streptomyces scabiei is identified and an antibiotic agent is characterized to characterize the antibiotic agent. Expand
Free radical scavenging and antielastase activities of flavonoids from the fruits of Thuja orientalis
TLDR
Bioassay-guided fractionation of the MeOH extract of Thuja orientalis fruits using a DPPH (2,2-diphenyl-1-picrylhydrazyl) assay led to the isolation of 9 flavonoids, which exhibited potent anti-oxidant activities. Expand
Isoliquiritigenin Selectively Inhibits H2 Histamine Receptor Signaling
TLDR
The results demonstrate that isoliquiritigenin is an effective H2R antagonist and provides the basis for designing novel H1R antagonist. Expand
The inhibitory effect of polysaccharides isolated from Phellinus linteus on tumor growth and metastasis.
It was previously reported that polysaccharides (PL) isolated from Phellinus linteus strongly stimulated cell-mediated and humoral immunity. This study was undertaken to investigate theExpand
Synthesis and antimicrobial properties of imidazolium and pyrrolidinonium salts.
TLDR
The synthesized quaternary imidazolium and pyrrolidinonium salts containing a long alkyl chain and the introduction of a hydroxyethyl chain and methyl group into the imidrazolium ring structure leads to broad spectrum active antimicrobial agents which could be powerful bactericides. Expand
8-hydroxydihydrochelerythrine and 8-hydroxydihydrosanguinarine with a potent acetylcholinesterase inhibitory activity from Chelidonium majus L.
TLDR
Ethanol extract of the aerial portion of Chelidonium majus L. inhibited acetylcholinesterase (AChE) activity without a significant inhibition of butyrylcholinedine (BuChE), and three active constituents were isolated and identified. Expand
Chemical constituents from the leaves of Ilex paraguariensis inhibit human neutrophil elastase
TLDR
In the course of the screening program for HNE inhibitors from natural source, the MeOH extract of Ilex paraguariensis leaves showed strong HNE inhibitory effect, and it was demonstrated that dicaffeoylquinic acid derivatives and flavonoids exhibited potent H NE inhibitory activity. Expand

TLDR
Overall in vitro immune function was enhanced by addition of PL into culture of mouse spleen lymphocyte and i.p. injection into mouse, while beta-glucans and other polysaccharides only raised the level of T lymphocyte-mediated immunity. Expand
B-lymphocyte-stimulating polysaccharide from mushroom Phellinus linteus.
TLDR
Hot water extract prepared from the mycelial culture of mushroom Phellinus linteus stimulated polyclonal antibody production in an in vitro culture system and suggested that both the full molecular size and the sugar moiety were essential. Expand
Three naphthalenes from root bark of Hibiscus syriacus.
TLDR
Three new naphthalenes, designated as Syriacusins A-C, were isolated from the root bark of Hibiscus syriacus and showed cytotoxicity against some human cancer cell lines with an ED50 of 1.5-2.4 micrograms ml-1. Expand
