Support vector regression-guided unravelling: antioxidant capacity and quantitative structure-activity relationship predict reduction and promotion effects of flavonoids on acrylamide formation.

Scientific reports
We used the support vector regression (SVR) approach to predict and unravel reduction/promotion effect of characteristic flavonoids on the acrylamide formation under a low-moisture Maillard reaction system. Results demonstrated the reduction/promotio...

[Sodium Ferulate Attenuates Oxidative Stressvia Suppressing NALP3 Inflammasome and ERK Signal Pathway].

Sichuan da xue xue bao. Yi xue ban = Journal of Sichuan University. Medical science edition
OBJECTIVES: Study the gene and protein expression of NACHT-PYD-containing protein 3 (NALP3) inflammasome and extracellular regulated protein kinase (ERK), the intervention effects of sodium ferulate (SF) in human lung epithelial cells A549 under oxid...

The antioxidant and phenolic profiles of five green vegetables grown in Southern Nigeria.

Acta scientiarum polonorum. Technologia alimentaria
BACKGROUND: Regular consumption of vegetables has been associated with reduced risk of chronic diseases. The phenolic and free radical scavenging properties of five green vegetables grown in southern Nigeria were determined.

[Transformation of icariin by immobilized β-glucosidase and snailase].

Yao xue xue bao = Acta pharmaceutica Sinica
This study was performed to prepare immobilized β-glucosidase and snailase, then optimize and compare the process conditions for conversion of icariin. Immobilized β-glucosidase and snailase were prepared using crosslink-embedding method. The best co...

[Preparation of baicalein using thermophilic and sugar-tolerant beta-glucosidase].

Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica
The reaction conditions of baicalin hydrolyzed into baicalein by a kind of thermophilic and sugar-tolerant beta-glucosidase were studied in this paper. The beta-glucosidase could catalyze baicalin into baicalein well in the acetic acid-sodium acetate...

[Simultaneous determination of 16 flavonoids in the ginkgo dietary supplement tea by high performance liquid chromatography-tandem mass spectrometry].

Se pu = Chinese journal of chromatography
A method for the determination of 16 functional components of ginkgo dietary supplement tea such as catechin, vitexin, puerarin, isoflavoues aglycone, silymarin, quercetin, luteolin, apigenin, naringenin, hesperitin dihydrochalcone, kaempferol, hespe...

[Research on the Spectrophotometry for Determination of Flavonoids in Waste Residue of Stevia Rebaudiana].

Guang pu xue yu guang pu fen xi = Guang pu
A spectrophotometric method for the determination of flavonoids content in Waste Residue of Stevia Rebaudiana was established by comparing the UV-Vis spectra with three spectrophotometric methods: Direct, AlCl3 and NaNO2-Al (NO3)3-NaOH method. The ef...
