Abstract
: A new monoterpene rhamnoside, (+)-( R )- α -terpineol α -L-rhamnoside ( 1 ), along with ten known compounds ( 2 – 11 ) were obtained after purification of the ethanol extract of Cercis glabra legumes. Their structures were elucidated by spectroscopic evidence including NMR, optical rotatory dispersion (ORD), HR-ESI-MS and chemical hydrolysis. In the acetylcholinesterase inhibitory assay, compounds 3 and 8 showed high percentages of inhibition which were comparable to the activity of donepezil (a commercial drug, the positive control), and exhibited IC 50 values of 0.488, 0.391 mg/mL. These bioactive components could be promising acetylcholinesterase inhibitors.
期刊介绍:
Records of Natural Products is a journal of natural product chemistry. Reviews, book reviews, research papers and short reports are considered on the substances of plants, microbes and animals.
Discussions on the structure elucidation, synthesis of naturally occurring compounds and biological activity of natural compounds and plant extracts, biosynthesis of natural products and essential oils of aromatic plants as well as chemotaxonomy in the field of plants are welcomed in the journal.
All published research articles in Records of Natural Products have undergone rigorous peer review, based on initial editor screening and anonymized refereeing by expert referees.
