ABSTRACT
Objective To study the chemical constituents in fruits of Catalpa ovata. Methods Isolation and purification were carried out by silica gel, Sephadex LH-20, and active carbon column chromatography etc. Constituents were identified and structurally elucidated by physicochemical properties and spectral analysis. Results Eight compounds were obtained, six of them were determined as catalpol (Ⅰ), catalposide (Ⅱ), ursolic acid (Ⅲ), ?-daucosterol (Ⅳ), nonacosane (Ⅴ), ?-sitosterol (Ⅵ). (Conclusion)(All (~1H-NMR) and (~(13)C-NMR) chemical shifts of the compound) Ⅱ are assigned by UV, IR, ESI-MS, HREI-MS, (~1H-NMR), (~(13)C-NMR), HMQC, and HMBC techniques. Compounds Ⅲ and Ⅴ are isolated from the plant for the first time.
