Abstract:
Objective: To study the constituents in the roots of Picrorhiza scrophulariiflora. Methods: The constituents of P. scrophulariiflora were separated and purified with chromatographic methods. The structures were elucidated by spectroscopic methods and chemical analyses. Results: Ten compounds were isolated from the roots of P. scrophulariiflora and identified as β-sitosterol (1), palmitic acid (2), octacosyl trans-ferulate (3), 3β-hydroxystigmast-5-en-7-one (4), 6β-hydroxystigmast-4-en-3-one (5), caffeic acid methyl ester (6), protocatechuic acid methyl ester (7), vanillic acid (8), caffeic acid (9), and piceoside (10). Conclusion: Compounds 2-7 and 9 are obtained from the plants of Picrorhiza Royle for the first time.
