A water-soluble polysaccharide named as CSP-2 was isolated and purified from Chaenomeles speciosa by DEAE-Sepharose and Sephadex G-100 column chromatography. CSP-2 was composed of galactose (Gal), rhamnose (Rha), glucose (Glc) and xylose (Xyl) with a relative molar ratio of 3.8:1.6:1.2:0.4. The

To evaluate the health benefits of Chinese quince and quince phenolics, their antioxidant properties and antiulcerative activity were investigated in comparison with apple phenolics as a reference. The strength of antioxidant activity and DPPH radical scavenging activity of these fruit phenolics

To evaluate the phenolic extracts of Chinese quince, quince, and apple fruits, their phenolic profiles, antioxidant properties, and anti-influenza viral activities were investigated. Chinese quince had the largest amount of phenolics consisting mainly of high polymeric procyanidins. Quince had

To investigate the effects of processing Chinese quince fruit on the denaturation of phenolics and their food functions, fruit phenolic extracts were heated together with organic acid for up to 12 h. Chinese quince phenolic (mostly procyanidins) solution subjected to heat treatment changed from

The study aimed at assessing effects of freeze-dried Japanese quince fruit (FJQF; 0-9%) added to cookies to improve their antioxidant attributes during storage, sensory and volatile characteristics and acceptability by consumers. Cookies containing FJQF had 2-3.5-fold higher radical scavenging

The service tree (Sorbus domestica) is a wild fruit tree with immense medicinal and industrial value. This study aimed at determining the four major groups of antioxidants (flavonoids, phenolic acids and aldehydes, catechin and procyanidin) in rootstocks of Crataegus laevigata

Chemical composition and antioxidant activity of fresh and boiled Chaenomeles speciosa (CS) slices dried by different drying methods were determined. Data were analyzed by principle component analysis and cluster analysis. All dried boiled CS from dried fresh CS slices form main cluster. The results

A protocol for C. japonica micropropagation with a confirmation of genome size stability of the in vitro-propagated plantlets was developed. The highest number of shoots multiplied in vitro was obtained on Murashige & Skoog medium (MS) with 1.0 mg L^-1 N6-benzyladenine plus

Chaenomeles speciosa (Sweet) Nakai is a medicinal plant. Until date, there are no studies focusing on comparing the chemical profiles, antioxidant activity and α-glucosidase inhibitory activity of the dried fruits of C. speciosa from different production regions. In the study, we investigated the

Chinese quince fruits (Chaenomeles sinensis) have an abundance of lignins with antioxidant activities. To facilitate the utilization of Chinese quince fruits, lignin was isolated from it by auto-catalyzed ethanol organosolv pretreatment. The effects of three processing conditions (temperature, time,

Phenolic compounds are very important in the prevention and treatment of many civilization diseases, including colorectal cancer (CRC). In the present study we investigated and compared the phytochemical composition, antioxidant and cytotoxic activity of Japanese quince (Chaenomeles japonica L.)

Mugua, fruit of the genus Chaenomeles, is a valuable source of health food and Chinese medicine. To elucidate the bioactive compounds of five wild Chaenomeles species, extracts from fresh fruits were investigated by HPLC-DAD/ESI-MS/MS. Among the 24 polyphenol compounds obtained, 20 were flavan-3-ols

This study aimed to identify and quantify the chemical composition and polyphenolic profile of 19 cultivars of Chaenomeles × superba, Chaenomeles japonica, and Chaenomeles speciosa by liquid chromatography coupled with photodiode array detector and quadrupole time-of-flight
