ABSTRACT

To establish quality standard of Zhuang medicine Lonicera dasystyla, and provide scientific basis for the quality control of L. dasystyla. Characteristics of materia medica, microscopic features, TLC indentification, inspection, extractum and determination of chlorogenic acid, macranthoidin B, dipsacoside B were carried out through the experience, microscopic, physical and chemical methods, respectively. The standard of quality control was formulated thereafter. The characteristics of materia medica, microscopic features, TLC indentification were specified, the average contents of water, total ash, acid-insoluble ash, alcohol-soluble extracts, chlorogenic acid were 11.6%, 6.6%, 0.2% , 24.4%, 1.16%, respectively, the total amount of macranthoidin B and dipsacoside B was 3.13%. Quality standard of L. dasystyla was proposed according to experimental results. The quality of L. dasystyla can be controlled effectively with the quality standard.
