Article Synopsis
  • Beta-cryptoxanthin (β-CRX), a powerful antioxidant found in Satsuma mandarins, was studied for its potential anti-stress effects in women.
  • In a double-blind study with 23 female participants, those consuming β-CRX-rich orange juice showed lower levels of stress indicators compared to those on a placebo.
  • The findings suggest β-CRX may effectively reduce stress, supported by prior results from a mouse study indicating dose-dependent stress relief.

A lipid extract of Perna canaliculus (New Zealand green-lipped mussel) has reportedly displayed anti-inflammatory effects in animal models and in human controlled studies. However, the anti-inflammatory lipid components have not been investigated in detail due to the instability of the lipid extract, which has made the identification of the distinct active components a formidable task. Considering the instability of the active component, we carefully fractionated a lipid extract of Perna canaliculus (Lyprinol) and detected furan fatty acids (F-acids).

Curcuminoid synthase (CUS) from Oryza sativa is a plant-specific type III polyketide synthase (PKS) that catalyzes the remarkable one-pot formation of the C(6)-C(7)-C(6) diarylheptanoid scaffold of bisdemethoxycurcumin, by the condensation of two molecules of 4-coumaroyl-CoA and one molecule of malonyl-CoA. The crystal structure of O. sativa CUS was solved at 2.
