Abstract
Litsea costalis is a well-known medicinal plant in tropical and subtropical areas. Four significant flavonoids were extracted and characterized from the plant leaf extract. One component was discovered for the first time in flavonoid chemistry, flavan-4-ol, (3′, 4′-methylenedioxy-5,7-dimethoxy chroman-4-ol). Three flavonoids were discovered for the first time in this plant. The detected products are (+)-pinostrobin, (+)-onysilin, and (+)-pinocembrin. The fourth component was characterized for the first time in this plant and introduced in flavonoid chemistry. The extracted component antioxidant activity against DPPH indicated an IC50 value of around 30 µg/mL.
期刊介绍：
The purpose of Polycyclic Aromatic Compounds is to provide an international and interdisciplinary forum for all aspects of research related to polycyclic aromatic compounds (PAC). Topics range from fundamental research in chemistry (including synthetic and theoretical chemistry) and physics (including astrophysics), as well as thermodynamics, spectroscopy, analytical methods, and biology to applied studies in environmental science, biochemistry, toxicology, and industry. Polycyclic Aromatic Compounds has an outstanding Editorial Board and offers a rapid and efficient peer review process, as well as a flexible open access policy.
