Feasibility Analysis of Cutting Process of Fresh Menthae Haplocalycis Herba
Objective: To probe into feasibility of cutting process of fresh Menthae Haplocalycis Herba
in order to look for the best processing method by cutting. Method: GC chromatography was employed to determine the content of menthol with temperature program(initial temperature at 100 ℃
keeping 7 min;raised to 120 ℃ with 3.5 ℃·min-1
keeping 1 min;raised to 122 ℃ with 0.5 ℃·min-1
then raised to 220 ℃ with 35 ℃·min-1)
flow rate of 1.3 mL·min-1
injection volume of 1 μL and split ratio of 5:1.Quantitative analysis of volatile oil from Menthae Haplocalycis Herba was made and influence of different cutting methods on quality of its pieces was evaluated. Result: The content of volatile oil produced by fresh cutting process increased by 14.95% compared with that produced by using traditional cutting process so that the content of menthol increased by 5.60%. Conclusion: This fresh cutting process for Menthae Haplocalycis Herba should be advocated so as to improve pieces quality and processing efficiency.
