Glandular trichomes of medicinal plants: types, separation and purification, biological activities

Glandular trichomes (GTs) are one of the epidermal tissues medicinal plants which function in synthesis, storage, and secretion secondary metabolites. The active ingredients Chinese materials mostly metabolites plants. Accordingly, it is great research value to explore quality using GTs as starting point. However, most current studies on still at simple morphological identification stage, there few compounds secreted by metabolic processes. Here, we reviewed literature, summarized types plant GTs, separation purification technology, analysis biological activities metabolites, established a approach GTs. We hope provide reference for future GT inclusions metabolism.
