Although litchi has both nutrient and edible value, the extremely short preservation time limited its further market promotion. To explore processed litchi products with longer preservation time, litchi extract was selected as an alternative feedstock for production of bacterial cellulose (BC). After 2 weeks of static fermentation, 2.53 g/L of the BC membrane was obtained. The trace elements including magnesium (Mg) and sodium (Na) in the litchi extract were partly absorbed in the BC membrane, but no potassium (K) element was detected in it, curiously. Scanning electron microscope (SEM) photographs exhibited an ultrafine network nanostructure for the BC produced in the litchi extract. Analysis of the fourier-transform infrared spectroscopy (FTIR) confirmed the pellicles to be a cellulosic material. Interestingly, X-ray diffraction (XRD) results showed the BC membrane obtained from litchi extract had higher crystallinity of 94.0% than that from HS medium. Overall, the work showed the potential of producing high value-added polymer from litchi resources.

Article Synopsis
- The study explores the effects of litchi peel ethyl acetate extract on diabetes-related issues in a rat model, focusing on its flavonoid profile and potential glycemic control.
- The extract showed significant improvement in glucose tolerance and pancreatic health compared to untreated diabetic rats, comparable to the effects of metformin.
- Key flavonoids identified in the extract may contribute to enhancing glycogen storage and insulin signaling, suggesting its potential as a natural remedy for diabetes management and oxidative stress reduction.

Background: Lychee seeds were fermented by three kinds of bacteria (Lactobacillus plantarum, Saccharomyces cerevillus and ganoderma lucidum mycelium), and two effective strains were selected by two indexes of activity content and antioxidant, so as to further verify whether lychee seeds have waste multiplication effect and can protect cells damaged by oxidation from anti-inflammatory, anti-aging and safety.
Results: The contents of polyphenols, flavonoids and proteins in the solution fermented by Ganoderma lucidum mycelium did not increase, thus affecting the antioxidant capacity of the solution was far less than that of the water extract. The active content of the other two fermentation solutions was higher than that of the water extract, and the ability of scavenging free radicals of the two solutions increased with the increase of the volume fraction.

Bioactive flavonoid epicatechin has been reported in the peel of litchi fruit but isolated from its hydroalcoholic extracts. This study isolated epicatechin with cellular glucose uptake modulatory and ROS production inhibitory properties from the ethyl acetate (EtOAc) extract using a bioassay-guided approach. The fruit peel was defatted with hexane and sequentially extracted using dichloromethane (DCM), EtOAc, methanol (MeOH) and water.

Introduction: This review article gives an overview of the biogenic synthesis of metal nanoparticles (mNPs) while using extract as a reducing and stabilizing agent. The subtropical fruit tree i.e lychee contains phytochemicals such as flavonoids, terpenoids, and polyphenolic compounds which act as reducing agents and convert the metal ions into metal atoms that coagulate to form mNPs.

Ulcerative colitis (UC) is a common chronic, relapsing inflammatory bowel condition. Procyanidins (PC) are known for their antiangiogenic, anti-inflammatory, antioxidant, and antimetastatic properties. However, there is comparatively limited information on how PC interacts with UC.
