Chemical components from Sambucus adnata wall

Sambucus adnata Wall. belongs to Caprifoliaceae family. Phytochemical investigation on the aerial parts of S. adnata led to the isolation and identification of 17 known compounds (1–17) including triterpenoids and sterols. Compounds 1 and 8 are isolated from Sambucus adnata for the first time, and it is the first report that compounds 2, 5–6, 9–10, 12–15, and 17 are isolated from the plants of genus Sambucus. Importantly, three types of abundant components: (3β)-urs-12-en-3-yl stearate (0.33 g/kg, ursane type), (3β)-olean-12-en-3-yl stearate (0.17 g/kg, oleanane type), and lupenyl palmitate (0.52 g/kg, lupinane type) could be used as potential chemotaxonomic markers to distinguish among species of Sambucus.
