LC/MS Chromatograms of Multiple Extractions of PHY906. Extraction efficiency of PHY906 spray-dried extract. PHY906-6 powder was extracted with 80°C water (100 mg/ml) for 30 minutes. The remaining solid after a high speed spin of 10,000 rpm was extracted a second time with 80°C water for 30 minutes. LC/MS(+) spectra of each liquid extract indicate very similar peak patterns The efficiency for each extraction was approximately 80% as determined by dilution factors to maintain the TIC at 1.7e4 (1:50 for the first extraction and 1:5 for the second extraction) and by recovered masses.
