TL;DR: Eight new matrine-type alkaloids, flavesines G-J (1-4), alopecurine B (5), 7,11- dehydro-oxymatrine (6), 10-oxy-5,6-dehydrom atrine (7), and 10-oxysophoridine (8), along with nine known analogues (9-17) were isolated from the roots of Sophora flavescens.

TL;DR: Six unusual matrine-type alkaloid dimers, flavesines A-F (1-6, respectively), together with three proposed biosynthetic intermediates (7-9) were isolated from the roots of Sophora flavescens and represented an unprecedented dimerization pattern constructed by matrine and (-)-cytisine.

TL;DR: Four novel matrine-based alkaloids (1-4) were isolated from the seeds of Sophora alopecuroides and their structures were elucidated by means of spectroscopic methods and single-crystal X-ray diffraction.

TL;DR: Seven new phloroglucinol derivatives were isolated from the fruit tree Syzygium jambos together with four known triterpenoids and two known flavones and exhibited weak antioxidant activities under ferric-reducing antioxidant power and 2,2-diphenyl-1-picryhydrazyl radical-scavenging assays.

TL;DR: It was demonstrated that penduliflaworosin could inhibit vessel formation on Tg(fli1a:EGFP)y1-type zebrafish embryos and the structure and stereochemistry of crassifolin J was confirmed by single-crystal X-ray diffraction analysis, and the absolute configurations of crASSifolin K-M were determined by CD spectra.
