Optimization of Extraction Technology for Compound Hongjingtian Grain

Objective: To optimize extraction technology of compound Hongjingtian grain. Method: Water extraction technology for main component of compound Hongjingtian grain was optimized by contrast test method and orthogonal test method.Took yield of extract and extraction yield of salidroside as indexes to optimize extraction times,soaking time,water volume,extraction time and other factors. Result: Optimum extraction technology was soaked 0.5 h,extracted 2 times,first time extracted 2 hours with 10 times the amount of water,second time extracted 1 h with 8 times the amount of water. Conclusion: This experiment provided basis for water extraction technology of compound Hongjingtian grain, and this technology was reasonable and simple.
