[Study on the chemical constituents of Selaginella tamariscina (Beauv.) Spring].
OBJECTIVE
To study the chemical constituents of Selaginella tamariscina (Beauv.) Spring.


METHODS
Various chromatographic techniques were used to separate and purify the chemical constituents. Their physico-chemical properties and spectral data were used to elucidate the structures.


RESULTS
Four compounds were isolated from the n-BuOH fraction of the water-extracts. Their structures were identified as 1-hydroxy-2-[2-hydroxy-3-methoxy-5-(1-hydroxyethyl)-phenyl]-3-(4-hydroxy-3,5-dimethoxy)-propane-1-O-beta-D-glucopyranoside (tamariscinoside B, I), adenosine (II), guanosine (III), arbutin (IV).


CONCLUSIONS
Tamariscinoside B (I) is a new compound, while the others were isolated from Selaginella for the first time.
