ABSTACT: OBJECTIVE Systematically study the chemical constituents of Hibiscus tiliaceus METHODS The isolation and purification pounds were depended on silical gel, Sephadex LH – 20 and HPLC methods, and their structures were identified by their physical and spectral data. RESULTS pounds, friedelin (Ⅰ), pachysandiol(Ⅱ), glutinol (Ⅲ), lupeol (Ⅳ), germanicol (Ⅴ), stigmast-4-en-3-one (Ⅵ), stigmasta-4, 22-dien-3-one (Ⅶ), ergosta- 4, 6, 8(14), 22-tetraen-3-one (Ⅷ) , β-sitosterol (Ⅸ), stigmasterol(Ⅹ), were isolated and elucidated. pounds Ⅲ、Ⅳ、Ⅴ and Ⅷ were firstly isolated from this species.
