Preparation of bergenin from Ardisia crenata sims and Rodgersia sambucifolia hemsl based on microwave-assisted extraction/high-speed counter-current chromatography [PDF]

Separation and Purification Technology, 2010
Abstract In this paper, a simple method for the rapid extraction, separation and purification of bergenin from Ardisia crenata sims and Rodgersia sambucifolia hemsl by microwave-assisted extraction (MAE) coupled with high-speed counter-current chromatography (HSCCC) was developed. The MAE conditions were optimized and 2.0 g sample was extracted using

Novel method for improving ardicrenin content in hairy roots of Ardisia crenata Sims plants

Journal of Biotechnology, 2020
To develop an alternative medicine related with taxol/camptothecin, a hairy roots induction system for measuring triterpenoid saponin ardicrenin was established. In the current study, mature and healthy seeds of Ardisia crenata plants were selected for obtaining aseptic seedlings.

Structural studies of FR900359, a novel cyclic depsipeptide from Ardisia crenata sims(Myrsinaceae)

Journal of the Chemical Society, Perkin Transactions 1, 1989
The molecular structure and absolute configuration of FR900359, a novel cyclic depsipeptide from Ardisia crenata sims, has been determined by a combination of X-ray crystallographic analysis and g.c./m.s. study of the diastereomeric derivatives of its constituents.

Anti‐inflammatory activity of a new lactone isolated from the leaves of Ardisia crenata Sims

Chemistry & Biodiversity
AbstractOne new lactone (1) named Ardisicreolide C, together with three saponin compounds, Ardisiacrispin B (2), Ardisicrenoside A (3), Ardisiacrispin A (4) were isolated and identified from the leaves of Ardisia crenata Sims. The structures of 1–4 were elucidated by 1D, 2D‐NMR and HR‐MS spectra and together with the published data.

A new bergenin derivative isolated from the root of Ardisia crenata was determined to be 11-o-syringylbergenin by spectral methods. Other compounds were identified as spinasterol, series fatty acids, beta-sitosterol-beta-D-glucoside, norbergenin and sucrose respectively. The last three were obtained for the first time from the genus of Ardisia.

Mass spectral fragmentation analysis of triterpene saponins from Ardisia crenata Sims by electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry

Journal of Asian Natural Products Research, 2010
We used the electrospray ionization (ESI) Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS) technique to study the characteristic mass fragmentation patterns of eight triterpene saponins from Ardisia crenata Sims. Eight triterpene saponins were analyzed using parent mass list-triggered data-dependent multiple-stage accurate mass ...
