Objective:
To study the chemical constituents of the roots of Phlomis medicinalis.
Method:
The compounds were isolated and repeatedly purified by macroporous resin, silica gel column chromatography, TLC and PREP-HPLC. Their structures were elucidated by physical and chemical properties and NMR spectra.
Result:
Two iridoid glucosides were obtained and elucidated as 7-epilamalbide (1), chlorotuberoside (2).
Conclusion:
Compound 1 was a new compound, compound 2 was isolated from the plant for the first time.
