AIM:To investigate the chemical components of Boswellia carterii.
METHODS:Chromatographic technologies were used for separation and purification, while spectral analysis was used for structure elucidation.
RESULTS:Six compounds were isolated and their structures were identified as acetyl-alpha-boswellic acid (1), acetyl-beta-boswellic acid (2), lup-20(29)-ene-3 alpha-acetoxy-24-oic acid (3), alpha-boswellic acid (4), beta-boswellic acid (5) and acetyl-11-keto-beta-boswellic acid (6).
CONCLUSION:Compound 3 is a new constituent.
