The Composition, Antioxidant and Antibacterial Activity of Essential Oils from Five Species of the Magnoliaceae Family.

The leaves of Magnoliaceae family plants contain abundant essential oils (EOs), and these species can be used in many fields due to their high industrial, medicinal, and ornamental values. This study aims to identify the main compounds of the EOs from the leaves of five common Magnoliaceae species (, , , , ) using hydrodistillation, GC-MS analysis, and in vitro tests. Additionally, the antioxidant and antibacterial activities of the EOs were also evaluated.

Accumulation characteristics of plant flavonoids and effects of cultivation measures on their biosynthesis: A review.

Flavonoids, a kind of secondary metabolites with both edible, medicinal and antioxidant purposes, could be widely used in food, drug processing, forest products, chemical industry and many other fields. Flavonoid production in plant organs were influenced by numerous internal and external factors at various stages, leading to differential gene expression and transcription factors activity. This study reviews the characteristics of major flavonoids categories, their distribution and accumulation in different plant parts and analyzing their molecular mechanisms.

Effects of the nitrate and ammonium ratio on plant characteristics and Erythropalum scandens Bl. substrates.

Erythropalum scandens Bl. is a woody vegetable with high nitrogen demand that inhabits southern China. Ammonium and nitrate are the two main forms of inorganic nitrogen that plants directly absorb.

Expression of a novel dual-functional polypeptide and its pharmacological action research.

Aims: To develop a dual-functional medicine for hypoglycemic and anti-thrombus.

Main Methods: The long-acting glucagon like peptide-1 (5×GLP-1) and nattokinase (NK) were cloned by SOE PCR and gained the GLP-1 and NK fusion polypeptide after transformed into E. coli.
