Abstract

Seven flavanol derivatives, including three biflavanoids (1-3), two flavonoids (4 and 5), and two spirobiflavonoids (6 and 7), were isolated from the bark of Nothotsuga longibracteata. The structure of the undescribed compound 1 was elucidated based on HR-ESIMS, NMR spectroscopy, and electronic circular dichroism (ECD) calculations. All isolated flavanol derivatives were screened for their antioxidant capacity to scavenge DPPH and ABTS⁺.

期刊介绍： The Journal of Asian Natural Products Research (JANPR) publishes chemical and pharmaceutical studies in the English language in the field of natural product research on Asian ethnic medicine. The journal publishes work from scientists in Asian countries, e.g. China, Japan, Korea and India, including contributions from other countries concerning natural products of Asia. The journal is chemistry-orientated. Major fields covered are: isolation and structural elucidation of natural constituents (including those for non-medical uses), synthesis and transformation (including biosynthesis and biotransformation) of natural products, pharmacognosy, and allied topics. Biological evaluation of crude extracts are acceptable only as supporting data for pure isolates with well-characterized structures. All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymized refereeing by at least two expert referees.
