A New C13-Norisoprenoid from the Fruits of Chaenomeles sinensis
Chemistry of Natural Compounds, 2020A new C13-norisoprenoid, chaenomelesterpenoid C (1), was isolated from the fruits of Chaenomeles sinensis (Dum.Cours.) Koehne together with a known compound, linarionoside C (2). The structure of compound 1 was determined by NMR and MS analysis. Meanwhile, the protective effects of the compounds were tested against corticosterone-induced damage in PC ...

Chinese quince (Chaenomeles sinensis) seed gum: Structural characterization
Food Hydrocolloids, 2018Abstract Chinese quince seed gum (CQSG) is a novel potential viscosifier or stabilizer with good storage stability. In this work, CQSG was extracted from the surface of Chaenomeles sinensis (Chinese quince) seeds, and purified by DEAE-Sepharose Fast-Flow and Sephacryl S-400 HR chromatography; three fractions were obtained (CQSG-1, -2, -3).

Isolation of bioactive biphenyl compounds from the twigs of Chaenomeles sinensis
Bioorganic & Medicinal Chemistry Letters, 2016Investigation of the MeOH extract of Chaenomeles sinensis twigs resulted in the isolation of seven biphenyl compounds (1-7) including a new compound, chaenomin (1). The chemical structures of the isolated compounds were elucidated by extensive NMR data ((1)H and (13)C NMR, (1)H-(1)H COSY, HSQC and HMBC), specific optical rotation, and chemical reaction.

Chinese quince (Chaenomeles sinensis) fruits are rich in lignin, and too sour, astringent and woody to be eaten raw. More than 50 % of lignin in plant cell walls is covalently associated with carbohydrates to form lignin-carbohydrate complexes (LCC). In this study, LCC preparations were extracted from fruits harvested on the 15th day of the month from ...

Lignan Glycosides from the Twigs of Chaenomeles sinensis and Their Biological Activities
Journal of Natural Products, 2015Phytochemical investigation of the twigs of Chaenomeles sinensis led to the isolation and identification of six new lignan glycosides, chaenomiside A-F (1-6), along with five known ones (7-11). Their chemical structures were determined by spectroscopic methods, including NMR, MS, ECD, and GC/MS analyses.

Purification and Characterization of a Lectin from Chinese Quince (Chaenomeles sinensis) Fruit
Journal of Plant Biochemistry and Biotechnology, 2010Chaenomeles sinensis lectin (CSL) was isolated from Chinese quince fruit by affinity chromatography. The molecular weight of native CSL was estimated to be 16 kD by gel filtration chromatography. This lectin was found to contain approximately 57% carbohydrates.
