ABSTRACT: Objective: To study the effects of different drying methods on the activity of enzyme and the content of related active ingredients in Flos Lonicerae, and to provide experimental basis for determining the best drying method and improving the quality of Flos Lonicerae.
METHODS: Samples of Lonicera japonica were dried by microwave drying equipment, constant temperature blast drying and shade drying.
