China is one of the most important centers of diversity for Eriobotrya japonica Lindl. in the world. 3-p-coumaroylquinincacid (3-p-CoQA) was identified and quantified in the peel and pulp of the cultivars tested, this compound possessed relatively higher antioxidant activity, and may be excellent sources of phytochemicals and natural antioxidants.
(1R,3S)-1-methyl-1,2,3,4-tetrahydro-β-carboline-3-carboxylic acid (MTCA) is a β-carboline indole alkaloid naturally occurring in plants, foods, insects, and endogenously in mammals and humans. It exerts antioxidant and antithrombotic properties. MTCA is thought to be a possible causative substance of eosinophilia-myalgia syndrome associated with ingestion of L-tryptophan.
