Objective To investigate the chemical constituents from the underground parts of Salvia roborowskii. Methods The chemical constituents were isolated by the combination of silica gel, RP-18, Sephadex LH-20 and high performance liquid chromatography. Their structures were elucidated on the basis of spectroscopic analysis (MS, NMR, etc.). Results Eleven compounds, including 15-epi-danshenol-A(1), danshenol A(2), 15,16-dihydrotanshinone I(3), cryptotanshinone (4), tanshinone IIA (5), danshenxinkun B (6), sugoil (7), ferruginol (8), grandifolia C (9), normiltioane (10), and przewalskin(11), were isolated and identified. Conclusion Eleven compounds were all isolated from Salvia roborowskii for the first time.
