摘要：

A new compound, 1,3-O-diferuloylsucrose (1), and a synthetically known compound, 5,7-dihydroxy-6-methoxychromone (2), along with several known natural products, irilone (3), 4',5,7-trihydroxy-6-methoxyflavanone (4), tectorigenin (5), kaempferol (6), 4',5,7-trihydroxy-3',8-dimethoxyflavanone (7), 8-methoxyeriodictyol (8), hispidulin (9), and mangiferin (10) were isolated from the rhizomes of Iris unguicularis. Compounds 1, 6, 8 and 10 showed a considerable DPPH radicals scavenging activity. Their structures have been deduced through different spectroscopic techniques. The structure of compound 2 was also confirmed by single-crystal X-ray diffraction techniques as well.
