Abstract: To" 5 leaf honey of EnShi"of Gynostemma which contains the sweetness of material, using ultrasound, ZTC1+1 botained agent, SephadexG-10 gel chromatography extraction and separation technologies, high pure sweet substances, then on quality mass spectrometer to detect molecular weight and molecular elements contained in the type and quantity estimation and molecular formula. Preliminary study of the substance is not sucrose, glucose, but the molecular weight of 251.1393, the greatest possible C13H19N2O3 formula of the material.

Key words: Gynostemma pentaphyllum Makino, sweet taste matter
