From the seeds of the Celastrus angulatus, three new sesquiterpenoids were isolated. Their structures were established, on the basis of UV, IR, mass and 2D NMR spectrometry, as 1b-acetoxy-8a-benzoyloxy-9a,13-di(b-nicotinoyloxy)-b-dihydroagarofura n, 1b,2b-dihydroxy-6a-acetoxy-8b,9b-dibenzoyloxy-b-dihydroagarofuran and 1b,2b,8b,9b-tetrabenzoyloxy-6a-acetoxy-b-dihydroagarofuran.

Key words: ULTRAVIOLET SPECTROPHOTOMETRY, PYRIDINE P, SESQUITERPENE, INFRARED SPECTROPHOTOMETRY, MASS SPECTROGRAPHY, FURAN P, CELASTRUS ORBICULATUS
