Isolation and structural identification of chemical constituents from Selaginella tamariscina (Beauv.) Spring / 药学学报

ABSTRACT

<p><b>AIM</b>To study the chemical constituents of the water-extracts of Selaginella tamariscina (Beauv.) Spring.</p><p><b>METHODS</b>Various chromatographic techniques were used to separate and purify the constituents. Their physico-chemical properties and spectral data were used to elucidate the structures.</p><p><b>RESULTS</b>Nine compounds were isolated and identified as (2R,3S)-dihydro-2- (3',5'-dimethoxy-4'-hydroxyphenyl)-7-methoxy-5-acetyl-benzofuran (1), 3-hydroxy-phenpropionic acid-(2'-methoxy-4'-carboxy-phenol) ester (tamariscina ester A, 2), sygringaresinol (3), 1-(4'-hydroxyl-3'-methoxyphenyl)glycerol (4), ferulic acid (5), caffeic acid (6), vanillic acid (7), syringic acid (8), and umbelliferone (9).</p><p><b>CONCLUSION</b>Compound 1 and 2 are new compounds, and the others were isolated from Selaginella for the first time.</p>
