| Abstract: | A sesquiterpene was isolated from the seed oil of Celastrus orbiculatus and identified as 1α,6β-diacetoxy-9β-benzoyloxy-β-dihydroagarofuran by 1H NMR, 13C NMR and X-ray diffraction. The crystal belongs to orthorhombic system, P212121 space group, a=0.9192(2)nm, b=1.1239(3)nm, c=2.4421(5)nm, V=2.5229(10)nm3, Z=4, d=1.207 g/cm3, F(000)=984, C26H34O7, Mr=458.53, R1=0.0383, w R 2 =0.0775. |
