Hemicelluloses and summative analysis of timothy hay.
Abstract The four hemicellulose fractions of timothy hay showed an increase in the ratio of pentose molecules per uronic acid molecule with the increase in alkalinity of the solvent required to extract them. A summative analysis of the constituents of timothy hay was made.
Objective To study the best extracting technology of Compound Taizishen Granule prescription.Methods The total polysaccharides and total saponins were determined by UV spectrophotometer.With the content of total polysaccharides and total saponins as comprehensive indexes,orthogonal test was applied to investigation of the water addition,extraction time,and extraction times for optimizing the best extracting technology.Results The best extracting technology was using 10 times the amount of water,extracting 3 times and 1.5 h per time.Conclusion The extraction technology is safe and effective,which can be used as extraction for Compound Taizishen Granule prescription.
