METHODS

Column chromatography with silica gel and polyamide was employed for the isolation and purification of ingredients. The structures were elucidated by spectral method.

RESULT

Three iridoid glycosides were obtained and elucidated as mussaenoside, shanzhiside methyl ester and lamalbid.

CONCLUSION

All the three compounds were separated from P. dicora for the first time.
