Zusammenfassung:	The invention discloses a method for improving the preservation efficiency of rosmarinic acid in a rosemary material, which comprises the following steps: S1, picking: harvesting fresh rosemary leaves, and removing stems; s2, sample cleaning: cleaning the collected leaves, and spin-drying the leaves by using a spin-drying machine; s3, pre-freezing the sample: carrying out pre-freezing treatment on the cleaned and spin-dried sample in an ultralow-temperature refrigerator or liquid nitrogen; and S4, freeze vacuum drying: putting the sample subjected to pre-freezing treatment in the previous step into a freeze dryer for drying treatment, and then carrying out freeze-drying treatment. By adopting the detection and preservation method designed by the invention, after the fresh rosemary leaves are treated by a vacuum freeze drying technology, the preservation effect of the effective component rosmarinic acid in the rosemary is extremely remarkable by vacuum freeze drying, and after the rosemary is treated by vacuum
