Molecular characteristics and antitumor capacity of Glycan extracted from Cynomorium songaricum

Glycan were isolated from Cynomorium songaricum and flavone was extracted from Ginkgo leaf. This glycan was well fractionated into three fractions (CSG-F1, CSG-F1, and CSG-F3). The spectra were recorded at the absorbance mode from 4000 to 400 cm(-1) (mid infrared region) at the resolution of 8 cm(-1). The fourier transform infrared (IR) spectrum displayed a broad peak at 3438 cm(-1) and 2928 cm(-1) that corresponded to the stretching vibration of -OH group. The Ginkgo leaf flavone markedly inhibited the growth of human liver carcinoma cell line HepG2. However, C. songaricum glycan did not displayed strong antitumor activity. (C) 2011 Elsevier B.V.
