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.
从锁阳中分离出糖，并从银杏叶中提取黄酮。该糖被很好地分离成三个部分（CSG-F1、CSG-F2 和 CSG-F3）。在 4000 到 400 厘米（中红外区）之间以 8 厘米（1）的分辨率记录光谱。傅里叶变换红外（IR）光谱在 3438 厘米（1）和 2928 厘米（1）处显示出对应于-OH 基团的伸缩振动的宽峰。银杏叶黄酮明显抑制人肝癌细胞系 HepG2 的生长。然而，锁阳聚糖没有表现出很强的抗肿瘤活性。
