Research ArticleOpen accessIn the abstractAnalysis of Constituents and Bacteriostatic Activity of Essential Oil Extracted from Sea Buckthorn Seeds by Different MethodsHepeng Zhao, Fuyin Zhao, Qian Xiao et al.Sea buckthorn is a homologous plant listed in Chinese pharmacopoeia. The Essential Oils (EOs) of Sea Buckthorn Seeds (SBTS) are widely used in medicine and health products in China, Russia and other countries. The extraction methods of SBTS with advantages of low cost, high yield and high activity have attracted considerable attention. In this study, the extraction rate, chemical compositions … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 2 · 4 Jun 2021 · 7,480 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Soybean Oil on Lipid Metabolism in Mucor circinelloides WJ11 by Metabolomic AnalysisCaili Sun, Aabid Manzoor Shah, Junhuan Yang et al.Oleaginous fungus Mucor circinelloides utilizes different carbon sources associated with sustainable production of lipids, using soybean oil as carbon source, the fungus accumulated more intracellular lipids. Nonetheless, the metabolic changes in M. circinelloides upon vegetable oil as main carbon source have not been yet reported. Therefore, this study was conducted to investigate the metabolomics of M. circinelloides WJ11 cultivated in … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 2 · 9 Apr 2021 · 7,199 accessesView PDFCite
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 · 6,985 accessesView PDFCite
Research NotesOpen accessIn the abstractThe Phytol-rich Essential Oil from Fresh Medicago hispida Exerts Significant Inhibitory Activity against Escherichia coliLixue Zheng, Leijie Ben, Zhumei Cui et al.Medicago hispida is one of the most widely distributed and commonly cultivated plants of the genus Medicago in China. It is mainly consumed as a vegetable. In this paper, the extraction, chemical composition and antimicrobial potential of the essential oil from fresh M. hispida (EOFMH) were conducted and evaluated for the first time.
