Complete 1H and 13C assignments of 40-epi-(N1-tetrazolyl)-rapamycin (ABT-578) in DMSO-d6 were made using 1H, 13C, DQCOSY, ROESY, TOCSY, HSQC and HMBC spectra. Comparing the assignments with those of rapamycin showed that in the published 13C assignments of rapamycin in DMSO-d6 the shifts for C-12 an
## Abstract Four new oligosaccharides (1–4), one new pregnane glycoside (5), and one new cardiac glycoside (6) were isolated from the roots of __Periploca forrestii__ Schltr. (Asclepiadaceae), a traditional Chinese medicine used for the treatment of rheumatoid arthritis and wounds. Their structures
