[Studies on identification of Sedum emarginatum]

To establish methods for identification of the whole plant of Sedum emarginatum Migo.

Macroscopic and microscopic observation and FTIR technique were used to authenticate this crude drug, and the identification characteristics were studied.

The stem cross section and the whole plant powder had some notable micro-characters. The infrared spectras of the samples collected in the different habitats and seasons were very consistent with each other.

The results can be used as the evidence for identification of this ethnomedicine.
