ABSTRACT

The 1H and 13C NMR spectra of camelliagenin A and A1-barrigenol from the seeds of Barringtonia asiatica were completely assigned for the first time by one- and two-dimensional homo- and heteronuclear studies (1H, 13C, DQCOSY, TOCSY, HMQC, HMBC) at 600 and 150.89 MHz. The article reports standard data that may be important for potential authors needing such information.
