Research ArticleOpen accessIn the abstractPreparation of Low-Sugar Herbal Buccal Tablet and its Antioxidant ActivityYuqing Wang, Mingjie Sun, Rui Xu et al.In this study, in order to prepare a low-sugar Herbal Buccal Tablet (HBT), Response Surface Methodology (RSM) was used to optimize the formula of HBT. HBT was prepared by wet granulation and tableting process on the basis of formula optimization. The in vitro antioxidant activity, glycemic index and particle microstructure of HBT were evaluated. The results showed that the optimal … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 1 · 8 Mar 2022 · 6,357 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntifungal Activity of Jatropha Curcas Linn on Candida Albicans and Candida Tropicalis Associated with Neonatal and Infantile Infections in Yola, NigeriaJames Hamuel Doughari, Martha AbrahamOne hundred and eighty (180) stool samples collected of neonates and infants from three selected health facilities in Yola, Adamawa State Nigeria. The samples were subjected to both microscopic, biochemical test and cultural identification. Bromocresol green agar and Germ tube test was used to identify Candida species. Culture of the stool samples on SDA yielded 32 yeast cells with Candida … …American Journal of Agricultural and Biological Sciences, Vol. 16, Issue 1 · 7 Sep 2021 · 7,533 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Crude Polyphenol Oxidase Activity in Buckwheat SproutsYuedong Song, Yangfang Zhang, Yilin Wang et al.Buckwheat sprouts can not only effectively reduce the trypsin inhibitor in buckwheat grain, but also improve the content of bioactive ingredients such as flavonoids and other effective components. However, Polyphenol Oxidase (PPO) in buckwheat sprouts causes browning of food, which limits the application of buckwheat sprouts in food. In addressing this problem, studying the characteristics of PPO in buckwheat sprouts … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 2 · 25 Jun 2021 · 6,486 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Oak Chip Treatments on Quality of Dry White Wines During AgingRongbin Li, Xiaofang Liang, Chunhua Song et al.The objective of the research was to evaluate the effect of different oak chip treatments on quality of Longyan dry white wine during aging. Phenolic substances, antioxidant activity and Cu2+ reduction force were measured. The results showed that wines treated with French oak chips (6 g/L) had significantly higher contents of total phenols (0.083 mg/mL) and flavonoids (0.063 mg/mL), also … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 1 · 26 Feb 2020 · 7,235 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of 1-Deoxynojirimycin Content and Phytochemical Profiles from Young and Mature Mulberry Leaves of Morus Spp.Yasinta Ratna Esti Wulandari, Vivitri Dewi Prasasty, Adrianus Rio, Cindy GeniolaMulberry leaves have been known to be rich in 1-Deoxynojirimycin (DNJ) which inhibits postprandial hyperglycemia by inhibiting α-glucosidase in the small intestine and thereby reducing the breakdown of starch and other complex sugar into glucose. Mulberry leaf extract also contains many other bioactive compounds and phytochemicals. They are very effective in supporting blood sugar levels and balancing cholesterol and triglycerides. … …OnLine Journal of Biological Sciences, Vol. 19, Issue 2 · 3 Jun 2019 · 11,074 accessesView PDFCite
