Barkley led to the isolation of twenty-five compounds, including sixteen flavonoids (1–15), one flavonolignan (16), one chromone (17), four benzoic acid derivatives (18–21), two triterpenes (22–23) and two sterols (24–25). The structures of these compounds were elucidated on the basis of spectroscopic analysis and comparison with previous literature data. Among them, 8 and 21were isolated from the genus Toxicodendron and 5, 9, 13, 17–20, 22 from the family Anacardiaceae for the first time. Furthermore, 21 had been identified only by LC/MS before. 20 was a synthetic product used as anthelmintics, newly identified as a natural product. Furthermore, the chemotaxonomic value of these isolates was also discussed in detail.Graphical abstract
