[Study on chemical constituents of Callicarpa peii]
1Institute of Clinical Pharmacology, Guangzhou University of Chinese Medicine, Guangzhou 510405, China.
Objective:
To study the chemical constituents of Callicarpa peii.
Methods:
The chemical constituents were isolated and purified by chromatographic methods and elucidated by spectral analysis, including UV, IR, MS, 1H-NMR and 13C-NMR.
Results:
Ten compounds were obtained and identified as oleanolic acid (1), 2beta, 3beta,19alpha-trihydroxy-12-en-28-ursolic acid (2), luteolin -7,4'-dimethylether (3), luteolin -3', 4', 7, -trimethylether (4), luteolin -4'-methylether (5), hydnocarpin (6), luteolin (7), lyoniresinol 3alpha-O-beta-D-glucopyranoside (8), kelampayoside A (9), kaempferol -3-O-glucuronide (10).
Conclusion:
All these compounds are isolated from Callicarpa peii for the first time and compounds 3, 4, 6, 8 and 10 are isolated from this genus for the first time.
