The effects of the plant growth promoter gibberellic acid (GA3) and plant growth retardant chlormequat chloride (CCC) on biomass and quality of Angelica dahurica var. formosana plants were investigated employing physiological and biochemical methods. Plants were sprayed with GA3 or CCC at rosette stage and coumarin content was analyzed by high performance liquid chromatography (HPLC) after harv...

In the fresh tissues of Prunus mahaleb L., three classes of phenolics were characterised: phenolic acid derivatives (main compound being o-coumaric acid glucoside), quercetin glycosides, and anthocyanins (cyanidin 3,5-diglucoside, cyanidin 3-sambubioside, cyanidin 3-xylosyl-rutinoside and cyanidin 3-rutinoside). Coumarin was also identified. The kernels showed a high content of coumarin (0.87 m...

PURPOSE To elucidate the effect of physicochemical properties of nanocarrier systems on drug delivery efficiency to the retina by eyedrop administration in mice, rabbits, and monkeys. METHODS Submicron-sized liposomes (ssLips) of different particle size, cholesterol content, surface charge, and multilamellar vesicles (MLV) were prepared by the hydration METHOD Fluorescence probe (coumarin-6...

In this article we have studied Förster Resonance Energy Transfer (FRET) using 2-aminopurine (2-AP), a structural isomer of adenine as donor and various Coumarins as acceptors inside AROSOL-OT (AOT)-water reverse micelles (RM) using steady-state and time-resolved fluorescence spectroscopies. We have used three sets of FRET and all the pairs except 2-AP-Coumarin-480 exhibited quite efficient FRE...

The ashgray blister beetle. EpiCtluta [abricii (LeConte); th e striped blister beetle. E. lilt/ala (F.) ; and the margined bli ster beetle, E. p estijer« Werner. collected in the field from plants of sweetclover low in coumarin content, fed preferentially in the Iaboratory on low-coumarin leaves when offered a choice between leaves from highand low-coumarin plants. The black bli ster beetle. E....

White sweet clover (Melilotus albus) cultivation, despite its many positive features such as the high yield of green mass, well protein content, is currently not widespread. This study aimed to determine effect different sowing densities (500, 1000, and 1500 seeds per m2) harvesting at growth stages (before budding, full flowering) on quality fodder from white (Adela variety). The field experim...

Abstract The article introduces the layout of a college course on analytical chemistry for pre-service teachers. aims at fostering teacher students’ professional knowledge by recapitulating Core Content Knowledge, introducing Specialized Knowledge , and complementing it with discipline-overarching Linked . Synthesizing these types is expected to support students in their processes meaning makin...

Platelet hyperactivity and platelet interaction with endothelial cells contribute to the development and progression of many cardiovascular diseases such as atherosclerosis and thrombosis. The impact of platelet activity with different pharmacological agents, such as acetylsalicylic acid and coumarin derivatives, has been shown to be effective in the prevention of cardiovascular disease. Artemi...
