Chemical constituents from Polygonatum odoratum

• We studied the chemical constituents of Polygonatum odoratum and obtained twenty-two compounds.
• The structures of compounds were elucidated by spectroscopic methods.
• Compounds 3, 5–7, 9–11, 15, 16 and 19 were firstly obtained from genus Polygonatum.
• The obtained constituents showed the relationships among the plants of Liliaceae family.

Twenty-two compounds, including five homoisoflavanones (1–3, 7 and 8), three isoflavones (9–11), flavone glycoside (19), one triterpenoid aglycon (5), two steroidal sapogenins (4, 6), five steroidal saponins (12, 13, 20–22), three lignanoids (14, 17 and 18) and two fatty acids (15 and 16) were isolated from the rhizomes of Polygonatum odoratum. The structures were elucidated by spectroscopic methods and by comparison of the reported spectral data. Additionally, the relationships between this plant and other species from Liliaceae family have also been discussed on the basis of the given compounds.
