Kapche, Gilbert D. W. F. published the artcilePrenylated arylbenzofuran derivatives from Morus mesozygia with antioxidant activity, HPLC of Formula: 56317-21-6, the publication is Phytochemistry (Elsevier) (2009), 70(2), 216-221, database is CAplus and MEDLINE.
Five prenylated arylbenzofurans, moracins Q-U, were isolated from Morus mesozygia (Moraceae). Their structures were elucidated on the basis of spectroscopic evidence. Along with these compounds, 3β-acetoxyurs-12-en-11-one, marsformoxide, moracin C, moracin M, moracin K, artocarpesin, cycloartocarpesin, morachalcone A were also isolated. Four of the five compounds (moracins R-U) displayed potent antioxidant activity.
Phytochemistry (Elsevier) published new progress about 56317-21-6. 56317-21-6 belongs to benzofurans, auxiliary class Metabolic Enzyme,PDE,Natural product, name is 5-(6-Hydroxybenzofuran-2-yl)benzene-1,3-diol, and the molecular formula is C14H10O4, HPLC of Formula: 56317-21-6.
