Objective To investigate the chemical constituents of pericarps of Huajiao (Zanthoxylum bungeanum). Method The n-butanol fraction of pericarps of Z. bungeanum was isolated and purified by macroporous resin column chromatography, silica gel column chromatography, Sephadex LH-20 gel column chromatography and semi-preparative HPLC. And their structures were elucidated by various spectroscopic methods, such as HR-ESI-MS, NMR, IR, CD, et al. Result A total of 25 compounds were isolated from the n-butanol fraction of pericarps of Z. bungeanum. They were identified as 2α,3β-dihydroxy-3α-vanilloylmethyl-γ-lactone (1), phellolactone (2), vanillic acid (3), isovanillic acid (4), 4-hydroxycryptone (5), ZP-amide A (6), ZP-amide B (7), ZP-amide D (8), oleracein E (9), bergapten (10), (±)-dorsteniol (11), orcinol glucoside (12), phloroacetophenone 4-O-β-D-glucopyranoside (13), (1R,2R,4S)-trans-2-hydroxy-1,8-cineole-2-O-β-D-glucopyranoside (14), (3S,6S)-6-ethenyltetrahydro-2,2,6-trimethyl-2H-pyran-3-yl-6-O-β-D-glucopyranoside (15), trans-linalool-3,6-oxide-7-O-β-D-glucopyranoside (16), betulabuside A (17), daidzin (18), puerarin (19), hyperin (20), quercetin 3-O-β-D-glucopyranoside (21), quercetin 3-O-β-D-rhamnoside (22), avicularin (23), hesperidine (24) and tamarixetin 7-rutinoside (25). Conclusion Compound 1 is obtained as a new γ-lactone named as isophellolactone. Compounds 1—2, 9, 11, 13—14, 17—19 and 22—23 are isolated from Zanthoxylum for the first time. Compounds 5, 10, 15 and 24 are isolated from Z. bungeanum for the first time.
