OBJECTIVE
To study the flavonoids constituents of Trachelospemum jasminoides.
METHODS
The compounds were separated and purified by column chromatography with silica gel, and identified by IR, MS, NMR and 2D-NMR.
RESULTS
Six flavonoids were identified as apigenin (I), apigenin 7-O-beta-glucoside
A preparative two dimensional hydrophilic interaction liquid chromatography/reversed-phase liquid chromatography (Pre-2D-HILIC/RPLC) method was established to separate and purify the components in Trachelospermum jasminoides. The pigments and strongly polar components were removed from the crude
High-resolution-mass-spectrometry (HR-MS) methods rapidly provide extensive structural information for the isolation of metabolites in natural products. However, they may occasionally provide more information than required and interfere with the targeted analysis of natural products. In this study,
This paper is intended to review advances in the botanical, phytochemical, traditional uses and pharmacological studies of the genus Trachelospermum. Until now, 138 chemical constituents have been isolated and characterized from these plants, particularly from T. asiaticum and T. jasminoides. Among
