OBJECTIVE
To study the chemical constituents from the aerial parts of Polygomun aviculane.
METHODS
The chemical constituents were isolated by silica gel column chromatography and preparative silica thin layer chromatography, and their structures were elucidated on the basis of physico-chemical evidences and spectroscopic analysis (IR, MS, 1H and 13C-NMR).
RESULTS
Seven phenolic compounds were identified as rosmarinic acid (1), gallic acid (2), gentisic acid 5-O-(6'-O-galloyl)-beta-D-glucopyranoside (3), caffeic acid (4), p-coumaric acid (5), ethyl caffeate (6) and acteoside (7), respectively.
CONCLUSIONS
Compounds 1, 3, 6 and 7 were isolated from this plant for the first time. These results provided theoretical evidences for the further bioactive investigation on this plant.
