Induction of defence mechanisms in grapevine leaves by emodin- and anthraquinone-rich plant extracts and their conferred resistance to downy mildew.
TLDR
HPLC-DAD-MS analysis showed that these two natural extracts contain many phenolic compounds belonging to the anthraquinone family, such as rhein, frangulin A, emodin, aloe-emod in, chrysophanol, and physcion. Expand
Isolation and determination of flavonol glycosides from Epilobium species
Abstract Centrifugal partition chromatography has been applied to the separation of flavonol glycosides from Epilobium parviflorum (Onagraceae). Using these glycosides, a method is described forExpand
The isolation of eleutherococcus senticosus constituents by centrifugal partition chromatography and their quantitative determination by high performance liquid chromatography
An investigation of Eleutherococcus senticosus roots, using centrifugal partition chromatography as a key intermediate separation step, has led to the straightforward isolation of eight constituents.Expand
Acetylated saponins with molluscicidal activity from Sapindus rarak: Unambiguous structure determination by proton nuclear magnetic resonance and quantitative analysis
Four monodesmosidic triglycosides, bearing up to two acetyl moieties on the terminal sugar, have been isolated from the pericarp of fruits of Sapindus rarak DC (Sapindaceae). The positions of theExpand
Determination of canthaxanthin in the red coral (Corallium rubrum) from Marseille by HPLC combined with UV and MS detection
TLDR
The results give the first evidence of the presence of canthaxanthin, 4,4′-diketo-β-carotene, as the major carotenoid in all samples of C. rubrum. Expand
Comprehensive analysis of Phyteuma orbiculare L., a wild Alpine food plant.
Plants which have been traditionally eaten by the alpine population may provide new opportunities for agricultural development in mountain regions. In this context we have investigated the chemicalExpand
Centrifugal counter-current chromatography, a promising means of measuring partition coefficients
Centrifugal counter-current chromatography (CCCC) was examined as a means of measuring lipophilicity values. Using an aqueous buffer as the stationary phase and 1-octanol as the eluent, seventeenExpand
High-performance liquid chromatographic determination of molluscicidal saponins from Phytolacca dodecandra (Phytolaccaceae).
TLDR
A comparison of different extraction procedures showed that with cold water predominantly monodesmosidic saponins were obtained, whereas hot water gave mainly bidesmosidics (non-molluscicidal) sap onins. Expand
A study of the flexural strength and surface hardness of different materials and technologies for occlusal device fabrication.
TLDR
Acrylic resins were less flexible than polyamide and nonacrylic occlusal device materials for 3D printing but had higher and more consistent values of surface hardness. Expand
