Lyophilisation of Traditional Chinese Medicine decoctions
Traditional Chinese Medicines (TCM) are usually prepared by mashing and boiling in water. This process is called decoction. Thereby, health beneficial compounds are extracted from herbal and plant material. If not directly administered, these extracts can be preserved for a longer shelf life using lyophilisation. In this Short Note we highlight the lyophilisation procedure of Tianma Gouteng Yin (TGY), as a TCM model decoction. TGY is a widely used medicine applied to treat Parkinson’s disease (PD) like symptoms. Recently, it has been reported that this TCM decoction exerts neuroprotective effects in animal and cell models of PD.
Total fat determination in milk powder by Soxhlet Extraction
A simple and reliable procedure for the fat determination in milk powder is introduced. The sample is hydrolyzed with the HydrolEx H-506 and extracted with the FatExtractor E-500. This application follows official methods (EN 98/64/EG, ISO 14156:2001, AOAC 945.16). The determined fat contents correspond well to the expected values, with low relative standard deviations (rsd)
