Analysis of Chemical Composition and Antioxidant Activity of Idesia polycarpa Pulp Oil from Five Regions in China.

ABSTRACT: Idesia polycarpa pulp oil (IPPO) has the potential to become the new high-quality vegetable oil. The chemical parameters, fatty acid composition, bioactive ingredients, and antioxidant capacity of five Chinese regions of IPPO were studied comparatively, with significant differences among the regions. The oils were all abundant in unsaturated fatty acids, including linoleic acid (63.07 ± 0.03%-70.69 ± 0.02%), oleic acid (5.20 ± 0.01%-7.49 ± 0.03%), palmitoleic acid (4.31 ± 0.01%-8.19 ± 0.01%) and linolenic acid (0.84 ± 0.03%-1.34 ± 0.01%). IPPO is also rich in active substances such as tocopherols (595.05 ± 11.81-1490.20 ± 20.84 mg/kg), which are made up of α, β, γ and δ isomers, β-sitosterol (1539.83 ± 52.41-2498.17 ± 26.05 mg/kg) and polyphenols (106.77 ± 0.86-266.50 ± 2.04 mg GAE/
