High performance liquid chromatography (HPLC) with diode array detection (DAD) and electrospray ionization tandem mass spectrometry (ESI/MS/MS) was used to analyze the main components in the methanol extract of Fructus Aurantii (FA) and the metabolites in rat biological samples after oral administration of the methanol extract of FA. There were 31 constituents identified in the extract of FA in...

to study the effect of soil moisture variation on growth and steviol glycosides contents in stevia (stevia rebaudiana b), a potexperiment based on a randomized complete design with four treatments and three replications were conducted in a greenhouse of agricultural biotechnology research institute of iran (central region, isfahan), in 2012. experimental treatments applied as a combination of v...

flavonoids are wide range of phytochemical with various pharmacological effects including antioxidant, anti-inflammation, anti-platelet, anti-allergic, cytotoxicity, reduce risk for heart disease or cancer etc. these flavonoids inhibited various enzymes such as prostaglandin synthase, lypoxygenase, cyclooxygenase, and induced detoxifying enzyme systems such as glutathione s-transferase. flavono...

The safety of steviol glycosides is based on data available on several individual steviol glycosides and on the terminal absorbed metabolite, steviol. Many more steviol glycosides have been identified, but are not yet included in regulatory assessments. Demonstration that these glycosides share the same metabolic fate would indicate applicability of the same regulatory paradigm. In vitro incuba...

Levels of phenolic glycosides and protein inßuence the quality of aspen leaves to herbivorous insects, and vary in relation to genetic and environmental factors. This research was conducted to assess the independent and interactive effects of phenolic glycosides and protein on the performance and detoxication enzyme activities of gypsy moths, Lymantria dispar (L.), and forest tent caterpillars,...

In tobacco seedlings (Nicotiana tabacum L.), glucose from supplied uridine diphosphate-[U-(14)C]glucose was first incorporated into steryl glycosides and later into acylated steryl glycosides. However, when [(14)C]cholesterol was used as substrate, the acylated steryl glycosides became labeled earlier than the steryl glycosides. With [(14)C]cholesteryl glucoside as substrate, most of the radioa...

Four kaempferol glycosides and five quercetin glycosides have been isolated from a methanolic extract of Paederia scandens var. mairei leaves and stems, in which in addition four un­ known glycosides of kaempferol and quercetin are present in a trace. Nine flavonol glycosides including a new glycoside quercetin 3-0-rutinoside-7-0-xylosylglucoside (paederinin) were identified by PC, HPLC, UV spe...

Sea cucumbers belonging to echinoderm are traditionally used as tonic food in China and other Asian countries. They produce abundant biologically active triterpene glycosides. More than 300 triterpene glycosides have been isolated and characterized from various species of sea cucumbers, which are classified as holostane and nonholostane depending on the presence or absence of a specific structu...
