A New Cyclohexanone Derivative from the Leaves of Bridelia stipularis

A new cyclohexanone derivative (stipularone) was isolated from the leaves of Bridelia stipularis (L.) Blume and characterized using 1D and 2D NMR spectroscopy (PMR, 13 C NMR, HSQC, DEPT-135, COSY, and HMBC) and HR-ESI-MS. Four known compounds were also identified, 3-(4′-hydroxyphenyl)-2-propenoic ac...

Zusammenfassung:A new cyclohexanone derivative (stipularone) was isolated from the leaves of Bridelia stipularis (L.) Blume and characterized using 1D and 2D NMR spectroscopy (PMR, 13 C NMR, HSQC, DEPT-135, COSY, and HMBC) and HR-ESI-MS. Four known compounds were also identified, 3-(4′-hydroxyphenyl)-2-propenoic acid (4′′-carboxyl)-phenyl ester, β -amyrin, scopoletin, and 4-hydroxybenzoic acid, by comparing their 1 H NMR spectra with published results. The chemotaxonomic significance was discussed based on the structure of the isolated compounds.
