Object To study the chemical constituents of Dracaena cochinchinensis (Lour.) S. C. Chen. Methods The constituents were isolated on silica gel chromatography, preparative TLC, and spectral data. Results Six compounds were isolated and identified from the resin of D. cochinchinensis as: 1, 2, 4, 5-tetrachloro-3, 6-dimethoxybenzene (Ⅰ), cholest-4α-methyl-7-en-3β-ol (Ⅱ), cholest-4α-methyl-7-en-3-one (Ⅲ), hexacosane (Ⅳ), cholest-7-en-3β-ol (Ⅴ), cholest-7-en-3-one (Ⅵ). Conclusion Compounds Ⅳ-Ⅵ were isolated from D. cochinchinensis for the first time.
