Eleutheroside B (EB) is the main active constituent derived from the Chinese herb Acanthopanax senticosus (AS) that has been reported to possess cardioprotective effects. In this study we investigated the effects of EB on cardiac electrophysiology and its suppression on atrial fibrillation (AF).
OBJECTIVE
To investigate the chemical constituents of the rhizome of Anemone raddeana Regel, so as to find new active compounds.
METHODS
The ethanol extracts of the rhizome of Anemone raddeana were obtained by silica column, HPLC. The structures of the compounds were elucidated by means of
The effect of six compounds isolated from rhizome of Anemone raddeana on the superoxide generation in human neutrophils was investigated. The six compounds examined were 3-acetyloleanolic acid (AOA), oleanolic acid (OA), eleutheroside K (EK), oleanolic acid-3-O-alpha-L-rhamnopyranosyl-(1 -->
OBJECTIVE
To study the chemical constituents from Anemone flaccida.
METHODS
Chemical constituents were isolated by repeated column chromatography (silica gel, Toyopearl HW-40C and preparative HPLC). The structures were elucidated on the basis of spectral data analysis.
RESULTS
Twelve triterpenes
The rhizome of Anemone raddeana Regel, a Traditional Chinese Medicine (TCM) which has a robust history treating rheumatism and neuralgia. The total secondary saponin (TSS) from it has demonstrated antitumor activity. In this study, a rapid and validated LC-MS/MS method was developed to
As the dry rhizome of Anemone raddeana Regel, Rhizoma Anemones Raddeanae (RAR), which belongs to Ranunculaceae, is usually used to treat wind and cold symptoms, hand-foot disease and spasms, joint pain and ulcer pain in China. It is well known that the efficacy of RAR can be distinctly
