Preparative Isolation and Purification of Flavonoids and Protocatechuic Acid from Sea Buckthorn Juice Concentrate (Hippophaë rhamnoides L. ssp. rhamnoides) by High-Speed Counter-Current Chromatography
High-speed counter-current chromatography (HSCCC)—a support free all liquid–liquid chromatography technique—has been successfully used for the preparative isolation of isorhamnetin 3-O-β-d-glucoside,Expand
Nutritional assessment of processing effects on major and trace element content in sea buckthorn juice (Hippophaë rhamnoides L. ssp. rhamnoides).
TLDR
Consumption of sea buckthorn juice represents a beneficial source of chromium, copper, manganese, molybdenum, iron, and potassium for the achievement of the respective dietary requirements. Expand
Application of preparative high-speed counter-current chromatography/electrospray ionization mass spectrometry for a fast screening and fractionation of polyphenols.
This study presents the novel direct coupling of preparative high-speed counter-current chromatography with electrospray ionization mass spectrometry (HSCCC/ESI-MS-MS) for continuous MS dataExpand
Folate content in sea buckthorn berries and related products (Hippophaë rhamnoides L. ssp. rhamnoides): LC-MS/MS determination of folate vitamer stability influenced by processing and storage
AbstractA stable isotope dilution assay was adopted for quantitation of folate vitamers in sea buckthorn berries, juice, and concentrate using fourfold labeled folate isotopologues of the folateExpand
Vitamin C content in sea buckthorn berries (Hippophaë rhamnoides L. ssp. rhamnoides) and related products: a kinetic study on storage stability and the determination of processing effects.
TLDR
It is shown that storage of sea buckthorn juices for 7 d at cold temperature (6 degrees C) already resulted in a degradation of TAA of about 11% to 12%. Expand
Direct reaction of oximes with crotylsarin, cyclosarin, or VX in vitro
TLDR
The results obtained with the two sarin analogues indicate that the direct reaction with 2-PAM, obidoxime, or HI 6 could be used for non-corrosive decontamination purposes, especially, if sensitive biological surfaces like skin, mucous membranes, or wounds are considered. Expand
Effects of processing and of storage on the stability of pantothenic acid in sea buckthorn products (Hippophaë rhamnoides L. ssp. rhamnoides) assessed by stable isotope dilution assay.
A stable isotope dilution assay for quantification of pantothenic acid in sea buckthorn berries, juice, and concentrate using a four-fold labeled isotopologue of vitamin B5 as the internal standardExpand
Determination of processing effects and of storage stability on vitamin K1 (Phylloquinone) in Sea Buckthorn Berries (Hippophaë rhamnoides L. ssp. rhamnoides) and related products.
TLDR
The juices showed almost identical significant degradation of phylloquinone of about 18% to 32% at 6, 25, and 40 degrees C indicating that intensity of decomposition is independent of temperature and storage time in the range of consumer storage conditions. Expand
Characterization of Acylated Flavonoid Glycosides from Sea Buckthorn (Hippophaë rhamnoides) Juice Concentrate by Preparative HSCCC/ESI-MS-MS
A direct coupling of preparative high-speed countercurrent chromatography to electrospray ionization mass spectrometry (HSCCC/ESI-MS-MS) was used for a 'target-guided' isolation and characterizationExpand
Effects of processing and of storage on the stability of pantothenic acid in sea buckthorn products (Hippophaë rhamnoides L. ssp. rhamnoides) assessed by stable isotope dilution assay.
A stable isotope dilution assay for quantification of pantothenic acid in sea buckthorn berries, juice, and concentrate using a four-fold labeled isotopologue of vitamin B5 as the internal standardExpand
