Emodinol, ß-Glucuronidase Inhibiting Triterpene from Paeonia Emodi
Emodinol, a new oleane type triterpene, has been isolated from the chloroform soluble fraction of Paeonia emodi. The structure 1β, 3β, 23-trihydroxyolean-12-en-28-oic acid 1 has been assigned on the
Studies on the chemical constituents of Phyllanthus emblica
TLDR
Two new flavonoids are isolated from Phyllanthus emblica on the basis of extensive spectroscopic studies including 2D-NMR experiments.
Presence of antispasmodic, antidiarrheal, antisecretory, calcium antagonist and acetylcholinesterase inhibitory steroidal alkaloids in Sarcococca saligna.
TLDR
This study provides a sound mechanistic base for some of the traditional uses of the plant in hyperactive gut states, in addition to providing the first evidence for verapamil to possess additional AChE inhibitory activity.
Isolation and immunomodulatory properties of a flavonoid, casticin from Vitex agnus‐castus
TLDR
A flavonoid isolated from the aerial parts of Vitex agnus‐castus was found to be a potent immunomodulatory and cytotoxic compound and showed a potent suppressive effect on PHA stimulated T‐cell.
New Cholinesterase‐Inhibiting Triterpenoid Alkaloids from Buxus hyrcana
TLDR
The structure–activity relationship studies suggested that the presence of dimethylamino moieties at C(3) and C(20) is the most important factor influencing the activity of these compounds against the cholinesterase enzymes.
