Two new C-glycosylflavones from the leaves of Iris lactea var.chinensis
摘要:
Two new acylated C-glycosylflavones were isolated from the leaves of Iris lactea vat.chinensis,and their structures were elucidated on the basis of extensive NMR experiments and mass spectrometry methods and were assigned as 5-hydroxy-4´-methoxyflavone-7-O-(β-D-2""4""-diacetylrhamnopyranosyl)-6-C-[O-(α-L-6´´´-acetyl-glucopyranosyl)-1→2-β-D-glucopyranoside] (irislactin A) and 5-hydroxy-4´,7-dimethoxyflavone-6-C-[O-(α-L-2´´´,3´´´-diacetylrhamno-pyranosyl)-1→2-β-D-glucopyranoside] (irislactin B).
