- Abstract
The article presents a study on the use of liquid chromatography/time-of-flight mass spectrometry (LC/TOF-MS) and LC/UV as a method for the quantification of extracted saponins from green tea leaves. It notes that saponin, a steroid or triterpene glycoside found in plants, is difficult to estimate its total number due to its population inconsistency in a plant. It concludes that tea-leaf saponins are the active components in Fr2-3 and that it exhibited antihypercholesterolemic activity.
