Chemical constituents isolated from the roots of Sanguisorba officinalis L. and their chemotaxonomic significance

摘要

Phytochemical investigation of the roots of Sanguisorba officinalis L. led to the isolation of thirty-eight compounds, including seventeen triterpenoids (1-17), six monoterpenoid glycosides (18-23), six flavonoids (24-29), six phenols (30-35), two glycosides (36-37), and one lignan (38). The chemical structures of these compounds were elucidated on the basis of spectral data and by comparisons of spectroscopic data with reported values in the literature. Compounds 18, 29, and 36-37 were the first to be reported in the family Rosaceae, compounds 10, 12, 15, 27-28, and 38 were firstly identified from the genus Sanguisorba, and compound 11 was obtained from S. officinalis for the first time. The chemotaxonomic significance of these isolated compounds has also been discussed.
