[Abstract]
Objective To investigate the chemical constituents from the whole plant of Carpesium faberi. Methods Compounds were isolated by various chromatographic techniques, including silica gel, ODS, sephadex LH-20, and semi-preparative HPLC, and their structures were identified by comparison of their experimental spectroscopic data with their reported data. Results The phytochemistry investigation led to the isolation of 12 compounds, and their structures were elucidated as ent-kaurane-3β,16β,17-triol (1), 3-(hydroxy-acetyl)-1H-indole (2), 8,9,10-trihydroxythymol (3), 8-hydroxy-9,10-diisobutyryloxy-thymol (4), neryl-β-D-glucopyranoside (5), (3S)-linalyl-β-D-glucopyranoside (6), (1R,2S,4S,5R)-2,5-dihydroxy-p-menthane (7), luteolin (8), apigenin-7-O-β-D-glucopyranoside (9), medioresinol (10), pinoresinol (11), and a mixture of silybin and isosilybin (12). Conclusion All compounds except compound 7 are not only isolated from this plant for the first time, but also from this genus for the first time.
