loganic acid/スイカズラ属

OBJECTIVE To research the chemical constituents from stems and leaves of Lonicera macranthoides. METHODS Various column chromatographies were employed to isolate and purify the constituents. Their structures were elucidated by spectral analysis (IR, MS, 1H-NMR, 13 C-NMR) and chemical

Iridoid profiles of honeysuckle berry were studied. Compounds were identified by ultra-performance liquid chromatography coupled with electrospray ionization mass spectrometry UPLC-ESI-qTOF-MS/MS in positive and negative ions mode. The MS fragmentation pathways of detected iridoid glycosides were

The aim of the study was to evaluate the effect of the different methods of preparation of the blue honeysuckle (Lonicera caerulea L. var. Kamtschatica) cv. 'Wojtek' and their influence on the iridoid content of fruit juices and fresh and freeze-dried pomaces. Compounds were identified by

Iridoid and polyphenol profiles of 30 different honeysuckle berry cultivars and genotypes were studied. Compounds were identified by ultra-performance liquid chromatography coupled with electrospray ionization mass spectrometry (UPLC-ESI-qTOF-MS/MS) in positive and negative ion modes and quantified

The high content of minor biologically active substances in the fruits of wild-growing and cultivated varieties of honeysuckle, along with the low knowledge of the chemical composition of domestic varieties, determines the relevance of the study of their qualitative and quantitative composition.
