OBJECTIVE
To study the chemical constituents of Indocalamus latifolius leaves.
METHODS
The chemical constituents were isolated and purified with silica column chromatography and gel chromatography. Their structures were identified by physicochemical properties and various spectroscopic methods including NMR spectrum, MS, UV, etc.
RESULTS
Fourteen compounds were isolated from the ethyl acetate part as isovitexin (1), vitexin (2), orientin (3), homoorientin (4), vanillic acid (5), chlorogenic acid (6), caffeic acid (7), ferulic acid (8), friedelin (9), tricin (10), tricin-7-O-beta-D-glucopyranoside (11), fernenol (12), luteolin-6-C-glucopyranoside (13) and quercetin-3-O-glucopyranoside (14).
CONCLUSIONS
All compounds are isolated from this plant for the first time.
