Carotenoids in goji (Lycium barbarum L.) have excellent health benefits, but the underlying mechanism of carotenoid synthesis and color formation fruit ripening is still unclear. The present study uses transcriptomics metabolomics to investigate biosynthesis differences N1 (red fruit) N1Y (yellow at three stages ripening. Twenty-seven carotenoids were identified fruits during M1, M2, M3 periods...

The protective effect of Lycium ruthenicum Murr. against radiation injury was examined in mice. Kunming mice were randomly divided into a control group, model group, positive drug group and L. ruthenicum high dose (8 g/kg), L. ruthenicum middle dose (4 g/kg), L. ruthenicum low dose (2 g/kg) treatment groups, for which doses were administered the third day, seventh day and 14th day after irradia...

A novel flavonoid glucoside, ruthenicunoid A (1), together with eight known substances, were isolated from the fruits of Lycium ruthenicun Murr. Their structures were elucidated by extensive spectroscopic data and chemical methods. Especially, the absolute configuration of glucose residue in 1 was assigned by acid hydrolysis followed by derivatization and GC analysis. Biological evaluation towa...

Purpose: Arabinogalactan is the main active ingredient of Lycium barbarum polysaccharides, possessing various bioactivities. However, physicochemical properties arabinogalactans differ between fruit varieties, provenance, and harvest seasons. The study aimed at distinguishing these differences (arabinogalactans) Methods: We obtained 27 batches L. using hot water extraction, fractional precipita...

Hyperstable cysteine-rich peptides (CRPs) represent an underexplored superfamily of bioactives in functional foods. An example is wolfberry the Lycium barbarum family. Previously, we discovered a CRP, designated α-lybatide, from L. bark. Herein, report discovery β-lybatide, novel carboxypeptidase inhibitor belonging to different CRP family plant. Proteomic and transcriptomic analyses showed tha...
