In our study, the mixture of cellulase and pectinase were used to exploit plant matrix. The combination of these enzymes increased the extraction efficiency compared to single enzyme treatment. The fresh tea leaves, byproduct of the green tea processing, were utilized as materials for extracting. And the enzyme-assisted extraction was investigated. Firstly, the materials were treated with the mixture of cellulase and pectinase.

Zoanthid is a potential natural resource with many biological activities, such as antioxidant, antiviral, antiinflammatory, and cytotoxic activity. Therefore, this study aimed to evaluate the antioxidant activity of 70% ethanol crude extract and dichloromethane fraction from Zoanthus vietnamensis. The total polyphenol content of ethanol and dichloromethane extracts were 19.36 ± 1.37 and 24.95 ± 0.63 mg GAE/g extract, respectively.

This study aimed to extract and evaluate some properties and the capability of phenolic components from shallot (Allium ascalonicum L.) peels for usage as fish preservative. It was found that shallot peels extracted twice with 70 % ethanol solvent, within 60 minutes, at 60 oC and the ratio of solid/liquid 1/20 (g/mL) gave highest polyphenol and flavonoid yields. Total polyphenol content and total flavonoid content of the extract were 224.34±5.66 mg GAE/g DW and 255.11±4.35 mg QE/g DW, respectively.

In this study, a total of 30 yeast isolates were recovered from local fruits in Thua Thien Hue province. Genetic characterization based on the ITS sequences identified isolates belonging to 3 species including Saccharomyces cerevisiae, Lachancea fermentati, and Clavispora fructus, with high sequence homology (over 99%) compared to published sequences in the GenBank.

To unravel how the integrity of nuclear and mitochondrial circulating cell-free DNA (cfDNA) contributes to its plasma quantity in colorectal cancer (CRC) patients. Methods CfDNA from plasma samples of 80 CRC patients stratified by tumour stage and 50 healthy individuals were extracted. Total cfDNA concentration was determined and equal template concentrations (ETC) were analyzed by quantitative real-time PCR (qPCR) resulting in small and long fragments of KRAS, Alu and MTCO3.
