There is no study on the constituents of Cirsium Macckii Maximowicz var. koraiense Nakai (Carduaceae) except linarin from the herb.
By the extraction and fractionation (Chart Ⅰ) of the coarsely cutted roots of this plant, two crystals were obtained, white needle crystal m.p. 278∼280°(Ⅰ), and a crystalline substance m.p. 138∼140°(Ⅱ), (Ⅱ) was identified as β-sitosterol by infrared spectra, thin layer chromatography, gas chromatography, and color reaction etc.
From the flowers of this plant, a white crystalline substance m.p. 230∼230° was obtained. It is supposed to be a triterpen by the color reaction and infrared spectrum.
