Phytotoxicity of Antofine from Invasive Swallow-Worts

Phytotoxicity of Phenolic Acids From Cereals

Phytotoxicity of secondary metabolites from Aptenia cordifolia.

From the fresh leaves or twigs of Aptenia cordifolia, a total of 29 compounds were isolated, including the new tetranoroxyneolignan 18, the new dilignan 19, and the beta-ionone derivative 27, previously only known as a synthetic compound, together with 26 known compounds. The structures of the new products were determined by (1)H-, (13)C-, and 2D-NMR, as well as HR-MS analyses. The phytotoxic e...

Phytotoxicity of methylene blue to rice seedlings

Methylene blue is widely used in various industrial branches. Due to insufficient treatment, its occurrence in wastewater is frequently detected, which may result in serious environment problems to aquatic organisms. Hydroponic experiments were conducted with rice seedlings (Oryza sativa L. cv. XZX 45) exposed to methylene blue to determine the effective concentration using relative gr...
