Endophytes: a rich source of functional metabolites.
Biology and chemistry of endophytes.
This review focuses on new endophyte-related findings in biology and ecology, and also summarises the various metabolites isolated from endophytes.
Biologically active substances from the genus Artemisia.
Artemisia species, widespread in nature, are frequently utilized for the treatment of diseases such as malaria, hepatitis, cancer, inflammation, and infections by fungi, bacteria, and viruses.Expand
Involvement of nitric oxide in oxidative burst, phenylalanine ammonia-lyase activation and Taxol production induced by low-energy ultrasound in Taxus yunnanensis cell suspension cultures.
This work was to characterize the generation of nitric oxide (NO) in Taxus yunnanensis cells exposed to low-energy ultrasound (US) and the signal role of NO in elicitation of plant defense responsesExpand
In vitro anti-Helicobacter pylori action of 30 Chinese herbal medicines used to treat ulcer diseases.
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. UtilizingExpand
Inhibition of MAO A and B by some plant-derived alkaloids, phenols and anthraquinones.
A total of seventeen phytochemicals including seven alkaloids (piperine, strychnine, brucine, stachydrine, tetrandrine, frangchinoline and sinomenine), four phenols (paeonol, honokiol, magnolol andExpand
Inhibition of xanthine oxidase by liquiritigenin and isoliquiritigenin isolated from Sinofranchetia chinensis
Abstract. The methanol extract of the stem of Sinofranchetia chinensis inhibited the activity of xanthine oxidase in vitro. Bioassay-guided purification led to the isolation of liquiritigenin andExpand
Sulfation of a polysaccharide produced by a marine filamentous fungus Phoma herbarum YS4108 alters its antioxidant properties in vitro.
Free radicals and other reactive oxygen species (ROS) are generated by all aerobic cells and are widely believed to play a significant role in aging as well as a number of degenerative orExpand
Anti-Helicobacter pylori metabolites from Rhizoctonia sp. Cy064, an endophytic fungus in Cynodon dactylon.
A new benzophenone, named rhizoctonic acid (1), together with three known compounds monomethylsulochrin (2), ergosterol (3) and 3beta,5alpha,6beta-trihydroxyergosta-7,22-diene (4) were isolatedExpand
Nitric oxide potentiates oligosaccharide-induced artemisinin production in Artemisia annua hairy roots.
The purpose of the present study was to characterize the generation of nitric oxide (NO) in Artemisia annua roots induced by an oligosaccharide elicitor (OE) from Fusarium oxysporum mycelium and theExpand
