Research ArticleOpen accessIn the abstractEssential Oils from The Dropped Flowers of Camellia japonica: Extraction Optimization, Chemical Profile and Antibacterial PropertyYunqi Kong, Gaochao Wang, Xinyu Wang et al.Camellia japonica is one of the most economically valuable species that can be taxonomically placed in the Theaceae family. Many horticultural varieties of C. japonica have been cultivated as ornamental trees worldwide, owing to their charming flowers. However, young C. japonica flowers usually drop in a “decapitated” form during the peak flowering stage, causing a resource waste. In this study, … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 1 · 27 Jan 2021 · 6,991 accessesView PDFCite
Research ArticleOpen accessIn the abstractAcetylation Process and Antioxidant Activity of a Polysaccharide from Loquat (Eriobotrya japonica) LeavesYiting Xue, Xiao Ding, Ze Zhang et al.Chemical modifications of polysaccharides can provide an opportunity to obtain new agents with possible therapeutic uses. In this study, a water-soluble polysaccharide extracted from Loquat Leaves (coded LLPs) was purified by the column chromatography, which was used to investigate its acetylation process by the acetic anhydride method. The Degree of Substitution (DS) was used as the index, the effect of … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 1 Jan 2021 · 7,059 accessesView PDFCite
