Object To study the chemical constituents of Frullania muscicola Steph. (Frullaniaceae). Methods Seven compounds were obtained from the petroleum ether extract of F.muscicola by repeated chromatography over silicagel and Sephadex LH-20. Their structures were identified by analysis of their spectral data and chemical reactions.Results Three steroids and four flavonoids had been isolated and their structures were identified as:stigmasterol arachidate(Ⅰ), sitosterol(Ⅱ), apigenin-7, 4′-dimethyl ethers(Ⅲ), scutellarin-6, 4′-dimethyl ethers(Ⅳ), 6-hydroxyluteolin-6, 3′-dimethyl ethers(Ⅴ), scutel-larin-6-methyl ether(Ⅵ), and daucosterol(Ⅶ). Conclusion Compound I was new and the other six were obtained from this plant for the first time.
