Objective: To study the chemical constituents of the rhizome of [Beesiacalthifolia (Maxim.)Ulhr.], an endemic plant in China, and to provide basis for clarifying its effective components. Methods : Separation by silica gel column chromatography, and its structure was identified according to the spectral data of the compound (IR, MS, 1H NMR, 13 C NMR) and chemical methods. RESULTS: Five compounds were isolated from the chloroform extract of their rhizomes and identified as: ferulic acid (I), 25 dehydrated proteol 3 O β-D-xylopyranoside (II ), and limonol 3 O Beta D-xylopyranoside (III), Tetrasaponin I (IV), and Daucoside (V). Conclusion : Compounds I, II, III and V were isolated from this plant for the first time. Among them, II-IV was a ring-shaped pineomelous triterpenoid saponin.
