Abstract

Background: The current regulations regarding the storage of medicinal herbs do not define the storage temperature; instead, but the only requirement is that the plastic bags used for storing the medicinal herbs should be tightly sealed during storage. The practice of storing medicinal herbs at room temperature (28℃), causes many problems, including growth of insect pests on the stored medicinal herbs. Thus, it is necessary to understand the effect of insect pests on the quality of medicinal herbs stored at room temperature (28℃) for the improving the relevant regulations.
Methods and Results: Cnidium rhizome and Angelica radix were infested with Lasioderma serricorne F. adults and incubated at 28℃ for 2.5 and 5 months. The population of L. serricorne was established rapidly, and left many holes, cadavers, and feces on the stored medicinal herbs, thereby greatly damaging the product appearance and hygiene. In addition, active ingredients of the medicinal herbs were significantly decreased, probably reducing their medicinal quality as well.
Conclusions: These results indicate that the current regulations are not sufficient to prevent the establishment of storage insect pests and guarantee the quality and hygiene of stored medicinal herbs. Therefore, it is necessary to devise proper storage protocols and upgrade the current relevant regulations to maintain the quality of medicinal herbs during storage.
