摘要
A new flavolignan, isohydnocarpin A (1), together with three known flavolignans, isohydnocarpin (2), hydnocarpin B (3), and hydnocarpin D (4), was isolated from the leaves of Nelumbo nicifera. The structure of the new compound was determined based on spectroscopic methods including 1D and 2D NMR and MS spectrometry. The stereochemistry was determined by NOESY experiments.
