| Abstract: | Objective:To obtain and compare the ITS sequence from Chinese materia medica with the molecular biological technique, and provide the dependable criterion for the identification of ultramicro capsule from Chinese materia medica. Methods: From the experimental dry materials and ultramicro capsule from Flos Lonicae and Evodia Rutaecarpa, the total DNA was distilled, cloned to detect the internal transcribed spacer(ITS) ultramicro capsule of ribosomal DNA. Results:The sequences of ITS1,ITS2 and 5. 8S. of the two herbals were obtained. Their similitude was more than 99%. Conclusion:The analysis of ITS sequence can provide an effective criterion to identify the ultramicro capsule from Chinese materia medica. |
