    Abstract:
    OBJECTIVE: To study the chemical constituents of Eucommia ulmoides in Guizhou Province. METHODS: Silica gel, Sephadex LH-20, RP-18, MCI and semi-preparative HPLC were used to study the chemical constituents of Eucommia ulmoides, and the chemical structures were elucidated by application of spectral data. RESULTS: 16 compounds were isolated from the bark of Eucommia ulmoides. Their structures were identified as β-sitosterol (1), cycloeucalenol (2), betulinic acid (3), 24-methylenecycloartenone (4), cycloeucalenone (5), salicifoliol (6), pinoresinol (7), genipin (8) , alternariol (9), balanophonin (10), eucommidiol (11), pinoresinol-4'-O-β-D-glucopyranoside (12), eucommiol (13), deoxyeucommiol (14), 8-hydroxypinoresinol (15), and dehydrodiconiferyl alcohol -γ'-O-β-D-glucopyranoside (16). CONCLUSION: Seven compounds, including compounds 2,4 - 6,9, 10 and 15 are isolated from Eucommia ulmoides for the first time, and compound 14 is isolated from the bark of Eucommia ulmoides for the first time.
