Published: March 2013

Five new phenolic glycosides, hedyotosides A-E (1-5), including a new cyanogenic glycoside (1), along with 10 known compounds (6-15) were isolated from the whole plants of Hedyotis scandens. The structures of compounds 1-5 were established by extensive spectroscopic analyses and acid hydrolysis. All the isolated compounds were evaluated for their in vitro antiviral activity against respiratory syncytial virus (RSV) with cytopathic effect (CPE) reduction assay. Compounds 6 and 15 showed anti-RSV effects with IC(50) values of 20 and 25 μg/mL, respectively.

Effect of NaCl stress germination on microstructure and physicochemical properties of wheat starch.

College of Grain, Oil and Food Science, Henan University of Technology, No.100 Lianhua Street in Zhongyuan District, Zhengzhou, Henan 450001, China.

Germination can enhance the nutritional properties of wheat and improve its bioavailability, while simultaneously altering the microstructure of wheat starch, which further impacts its physicochemical characteristics. This work investigated the synergistic effects of germination and NaCl on the microstructure and physicochemical properties of wheat starch by applying a 60 mmol/L NaCl solution. The results indicated that germination significantly influenced both the chemical composition and microstructure of wheat starch, as evidenced by cracks and pores, variations in size, crystallinity, lamellar order, hydrogen bond disruption, branching degree, and molecular weight distribution.
