Dragon's blood is a famous traditional Chinese medicine produced from source plants under bio‐ or abio‐stress. Dracaena cochinchinensis (Lour.) S.C. Chen xylem (DX) is one of the most important sources of the medicine. In this work, a GC‐MS method was developed for analysis of the n ‐hexane extracts of DX with resin (DXR) and without resin (DXW). The repeatability of the method was also investigated for a metabolite comparative study of the different xylems. About 80 components were detected, 26 of which were identified in both DXR and DXN. Three sesquiterpenes ( τ ‐cadinol, τ ‐muurolon and α ‐cadinol) were first discovered in Dracaena cochinchinensis (Lour.) S.C. Chen. The chromatographs of the two plant materials were compared and differences of compounds were found. It showed that phytosterols showed a dramatic rise in content, and sesquiterpenes were found to be synthesized in DXR. Copyright © 2015 John Wiley & Sons, Ltd.
