Chemical constituents from Hibiscus tiliaceus

Objective To study the chemical constituents from the twigs and leaves of Hibiscus tiliaceus(Li medicine).Methods Compounds were isolated by repeated chromatography on silica gel and alumina gel column.Their structures were elucidated by chemical and spectroscopic methods.Results Fourteen compounds were isolated and identified as friedelin(1),β-sitosterol(2),vanillin(3),syriacusin A(4),hibiscolactone(5),scopoletin(6),cleomiscosin C(7),fumaric acid(8),kaempferol(9),quercetin(10),daucosterol(11),azelaic acid(12),succinic acid(13),and rutin(14).Conclusion This is the first report on the isolation of compounds 7,9,and 10 from the plants of Hibiscus Linn.,and compounds 3—5,8,and 12—14 from this plant.
