Description

technical field

[0001] The invention relates to the application of plant polysaccharides in the field of pharmacy, in particular to the application of yew polysaccharides in pharmacy. Background technique

[0002] The present inventor has disclosed yew polysaccharide extract and preparation method thereof in CN0129421.9, and its structural formula is:

[0003]

[0004] Hydrogen atom Chemical shift (peak intensity) Number of hydrogen atoms

[0005] H1 4.73725(0.9411) 1

[0006] H2 3.03529(1.000) 1

[0007] H5 3.51608(1.2129) 1

[0008] H3, 4, 6, 6 3.66585-3.76325(3.7320) 4
