Preparation of TTO/UF resin microcapsule via in-situ polymerization and modeling of its slow release
For slow release of tea tree oil (TTO), TTO were encapsulated by urea-formaldehyde (UF) resin via in-situ polymerization. The effects of curing time and drying condition on particle size, a...
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.
