Two new isoflavone glycosides, tectorigenin 7-O-beta-D-glucopyranoside-4'-O-[beta-D-glucopyranosyl-(1''''-->6''')-beta-D-glucopyranoside] (1) and iristectorigenin B 4'-O-[beta-D-glucopyranosyl-(1'' --> 6'')-beta-D-glucopyranoside] (2), together with 11 known compounds, including six isoflavones,
Oxidative stress has been identified as an underlying factor in the development of insulin resistance, β-cell dysfunction, impaired glucose tolerance and type 2 diabetes mellitus and it also play major role in kidney stone formation. The present study is aimed to elucidate the in vitro
Fractionation of a methanol extract obtained from rhizomes of I. spuria (Zeal) resulted in the isolation of seven iridalglycosides 5a,b, 6a-c, 7, 8. The structures of the aglycons and the position of the glycosidic bonds were elucidated by spectroscopic analyses. The nature of the sugar moieties was
A new 12a-dehydrorotenoid 1, 11-dihydroxy-9, 10-methylenedioxy-12a-dehydrorotenoid (1), together with a new isoflavonoid glycoside tectorigenin-7-O-beta-glucosyl-4'-O-beta-glucoside (3), were isolated and identified from the rhizomes of I. spuria (Zeal). In addition, 4 known compounds, tectorigenin
