Abstract:
Objective: To rapidly identify Cyathula officinalis and its adulterant C. capitata and C. officinalis*C. capitata and doped adulterant. Method: Properties combined with foam test method were used for identifying C.officinalis, its adulterant and doped adulterant. In the aspect of properties,6 aspects including shape,size,texture,color,smell and taste,were observed, smelled and tasted. In the aspect of foam test,the volume of foam produced was used as the determination index to investigate the sample amount,water amount, shaking time,particle size,water temperature,repeatability,adulteration ratio and its stability. Result: In the aspect of properties,C. officinalis and its adulterant showed obvious difference in the shape,size,color,texture,smell and taste,especially the red color and bitter taste of its adulterant. In the aspect of foam test,the optimum parameters were as follows:sample particle (screened with 3 sieves) 0.3 g,a test tube with plug and scale,water 10 mL and airtight,forced shaking up and down for 1 min,settling for 5 min. Such method can be used to identify C. officinalis, its adulterant and doped adulterant. The volume of foams produced by C. officinalis and its adulterant and different ratio of doped adulterant showed no change within 5-30 min,slightly decreases after 9 h; the higher adulteration ratio; the larger volume of foam and better stability. The 8 batches of C. officinalis and 8 batch of adulterants proved that the volume of the foams produced was all less than 2 mL in the C. officinalis,more than 13 mL in the adulterant is,and more than 5 mL in 5% doped adulterant, showing statistical difference. From the properties combined with foam test,5 specific identification elements were obtained for identifying C. officinalis, its adulterant and doped adulterant. Conclusion: Through the 5 specific identification elements,the properties combined with foam test can be used to distinguish the C. officinalis from its adulterant C. officinalis and C. officinalis*C. capitata and doped adulterant,characterized by accuracy,simpleness,short time,low cost and feasibility. It can provide a new method and reference for identifying C.officinalis from its adulterant and doped adulterant.
