Quantitative analysis of saponins in a tea-leaf extract

Abstract. A novel simple method using liquid chromatography/time-of-flight mass spectrometry (LC/TOF-MS) and LC/UV was established for the quantification of saponins in an extract from green tea leaves. The amount of saponins in a fraction with high in vitro antihypercholesterolemic activity, Fr2-3, was determined to be 72%.Cited by: 21Tea Saponin Powder chemical used in Chromatography is lab Tea Saponin Powder chemical used in Chromatography is lab, US $ 1 - 1 / Kilogram, Tea Extract, Powder, Seed.Source from Changsha Xian Shan Yuan Agriculture & Techniques for extraction and isolation of natural Apr 17, 2018 The chromatography behaviors of PDS and PTS were close to reversed-phase chromatography when comparing the chromatographic profiles of macroporous resin column chromatography to the HPLC chromatogram on a Zorbax SB-C 18 column .
