  • How to obtain maximum oil yield from peony seeds?
  • Optimized ultrasound-assisted extraction conditions (solid-to-liquid ratio of 1:7, ultrasonication time of 66 min, ultrasonication temperature of 55 °C and ultrasonication power of 395 W) were obtained by using response surface methodology to obtain the maximum oil yield from peony ( Paeonia suffruticosa Andr.) seeds.
  • Can we optimize the process of oil extraction from peony seeds?
  • The consistency between the model predicted value and the experimental value of oil yield indicated that the model was extensively applicable and that optimized conditions could be repeated to obtain the expected content value. Therefore, the model was considered to be available for optimizing the process of oil extraction from peony seeds.
  • How are peony seeds extracted?
  • The peony seeds were ground into powder by a mechanical grinder (Philips Co. Ltd. China) after the shells were manually removed, and the powder was sieved through 0.45 mm mesh and stored at 4 °C for extraction of oil and subsequent analyses of the proximate chemical composition. All reagents were analytical or guaranteed grade in this experiment.
  • Is ethanol a good extractant for oil from peony seeds?
  • It was concluded that optimization of UAE of oil from peony seeds was successfully performed. Ethanol was evaluated as the optimum extractant with healthy and eco-friendly characteristics as well as high oil yield.
  • Are tree peony seed yields higher under open-field cultivation than under forest intercropping?
  • Additionally, yield and oil contents of tree peony seed under different cultivation conditions (open-field cultivation and canopy density), and the seed yield of open-field cultivation was higher than that under forest intercropping.
  • Why do oil bodies obstruct in peony seeds?
  • According to the report of Zhao et al. [ 38 ], oil bodies stored in peony seeds examined by transmission electron microscopy were composed of related proteins and monolayer phospholipid membranes. To some extent, this structure caused a decrease in oil effusion to obstruct in oil body related proteins [ 27 ].
