Objective To study the chemical constituents of ethyl acetate extract from domestic Pfaffia glomerata. Methods The compounds were isolated and purified by silica gel, reversed-phase, Sephadex LH-20 column chromatography, and their structures were elucidated by spectroscopic analysis as well as chemical methods. Results Twenty compounds were identified as 1-undecanol (1), oleic acid (2), β-sitosterol (3), 2-hydroxy-4,6-dimethoxyacetophenone (4), oleanolic acid (5), pfaffianol A (6), benzene-1,4-diol (7), vanillic acid (8), iresinone (9), ethylcaffeate (10), oleanoicaeid-28-O-β-D-glucopyranosyl ester (11), allantoin (12), ajugasterone-C (13), β-ecdysterone (14), iresinoside (15), adenine (16), oleanolic acid 3-O-β-D-glucuronopyranoside (17), ficusoside B (18), pfaffiaglycoside B (19), and β-D-Glucopyranosyl-3-(O-β-D-glucopyranosyloxy)-oleanolate (20). Conclusion Compounds 7-10, 15, 17, 18, and 20 are isolated from this plant for the first time.
