Objective:
To study the optimum paper-roast conditions of Radix Vladimiriae.
Methods:
The contents of naphtha and costunolide and dehydrcostuslactone were used as estimated indexes. The paper-roast process of Radix Vladimiriae was studied by orthogonal design.
Results:
The optimum condition was adding moderate water and marinates firstly, after getting rid of the water and experimenting 6 hours' closed lay, cutting Radix Vladimiriae into slices with 10 centimeters and drying under natural condition. One layer paper by one layer Radix Vladimiriae slice roasted 2 hours at 120 degrees C.
Conclusion:
The paper-roast process is stable, controllable and can provide referenced foundation for the production of paper-roast Radix Vladimiriae.
