Colchicinoid glucosides from seedless pods of Thai origin Gloriosa superba. (June 2016) - Sahakitpichan, Poolsak
Graphical abstract: Dongduengosides A (2 ), B (3 ), and C (4 ) were isolated from seedless pods of Gloriosa superba . Highlights: Three new colchicinoid glucosides were isolated from seedless pods of Gloriosa superba . It is the first time to report the constituents from seedless pods of Gloriosa superba . This study provided the data of the colchicinoids from Thai origin Gloriosa superba . Abstract: Three new colchicinoid glucosides, dongduengosides A-C were isolated from seedless pods of Thai origin Gloriosa superba together with colchicoside, colchicine, 2-demethylcolchicine and luteolin 7- O -β-d -glucopyranoside. In addition, colchicine, 2-demethylcolchicine, 3-methylcolchicine, colchicoside, epi -catechin and quercetin 3- O -β-d -glucopyranoside were identified from seeds. The structure determinations were based on physical data and spectroscopic evidence including 1D- and 2D-experiments. This study showed that the different part of seedless pods and seeds provided the major difference in compounds.
