Objective:
To study on the chemical constituents of Callicarpa kochiana.
Methods:
The chemical constituents were isolated by chromatographic methods and structurally elucidated by spectral analysis.
Results:
Twelve compounds were obtained and identified as alpha-amyrin(I), 2beta, 3beta, 19alpha-trihydroxy-12-en-28-ursolic acid (II), oleanolic aicd (III), alpha-amyrin-3-0-beta-D-glucopyranoside (IV), ursolic acid (V), betulinic acid (VI), 2alpha, 3beta,23-trihydroxy-12-en-28-oic-0-beta-D-glucopyranoside (VII), 0-hydroxybenzoic acid (VI), pomolic acid (IX), myrianthic acid (X), beta-sitosterol (XI), dauricine (XII).
Conclusion:
All of these compounds are isolated from Callicarpa kochiana for the first time and compounds II, IV, VII, VIII, IX and X are reported for the first time from Callicarpa genus.
