investigation of the ethanol extract of the branch and leaves of Illicium majus resulted in the isolation of four new phenylpropanoid glycosides (1–4) and one new phenolic glycoside (9), along with 13 known ones. Spectroscopic techniques were used to elucidate the structures of the new isolates such as 3‐[(2R,3S)‐7‐hydroxy‐2‐(4‐hydroxy‐3‐methoxyphenyl)‐3‐(hydroxymethyl)‐2,3‐dihydro‐1‐benzofuran‐5‐yl]propyl
