Objective: To investigate the chemical constituents of anti-osteoporosis active extract of the processed Cibotium baronetz. Method: The components of C.baronetz were isolated on silica gel column chromatography and their structures were elucidated by chemical properties and spectroscopic evidence. Result: Eight constituents were isolated and identified as onitin (1)
pyromeconic acid (2)
maltol (3)
kojic acid (4)
5-hydroxymaltol (5)
protocatechuic aldehyde (6)
caffeic acid (7)
protocatechuic acid (8). Conclusion: Four α-hydroxy- 4H-pyran-4-one compounds were isolated from processed C.baronetz for the first time.
