Seven lignans and eight phenylpropanoids, including one new lignan, 7S,8R,8'R-5,5′-dimethoxyariciresinol-4-O-β-D-glucopyranoside (1), were isolated from the liquid juice of Phyllostachys edulis. Their structures were established by extensive spectroscopic analyses. The absolute configuration of the new compound was determined by comparing its experimental electronic circular dichroism (ECD) spectra with calculated ECD spectra. All compounds were evaluated for their anti-inflammatory activity and xanthine oxidase inhibitor activity, and the results showed that compound 9 exhibited a moderate activity in these two bioassays. In addition, all the compounds can be detected in health panda faeces by LC-MS.
