ABSTRACT
Objective To systematically study the chemical constituents in the roots of Gentiana macrophylla from Shaanxi Province. Methods Various column chromatographic techniques were used for isolation and purification of the principles. The structures were elucidated on the basis of spectral data (UV, IR, MS, (~1H-NMR), (~(13)C-NMR), (~1H-~1H COSY) and (~1H-~(13)C COSY), HMBC, and HMQC) and identified by comparing with the authentic substance. Results Five compounds were got from fat-soluble fraction. They are identified as N-pentacosyl-2-carboxy-benzoyl amide (Ⅰ), 5-carboxyl-3, 4-dihydrogen-1H-2-benzopyran-1-one (Ⅱ), erythrocentaurin (Ⅲ), roburic acid (Ⅳ), oleanolic acid (Ⅴ). Conclusion Compounds Ⅰ and Ⅱ are two novel ones. They are named as qinjiaoamide and erythrocentauric acid, respectively. Compound Ⅲ is isolated from the plants of Gentiana L. for the first time.
