Abstract:
The recycling of traditional Chinese medicine （TCM） wastes is an important research topic to be solved urgently in the industrialization of TCM resources. Rhei Radix et Rhizoma is a bulk Chinese herb mainly derived from Rheum palmatum，R. tanguticum，and R. officinale. At present，these three medicinal plants have been cultivated on a large scale and widely used in the fields of medicine，health care，food，cosmetics，and veterinary medicine，with an annual demand of more than 5 500 tons（1 ton=1 000 kg）. However，a large number of wastes such as non-medicinal parts and residues produced in the production and deep processing are discarded because there is no effective way of utilization，resulting in serious waste of resources and environmental pollution. The non-medicinal parts contain not only the chemical components and pharmacological effects similar to those of roots and rhizomes but also a variety of amino acids，mineral elements，and conventional nutrients. They have a long history of use，and the content of some resource components is higher than that in roots and rhizomes. In particular，their stems and leaves exhibit great potential to be consumed as food and medicine due to high safety. Besides，the content of anthraquinones in Rhei Radix et Rhizoma residue is high and it possesses good antibacterial activity. It can be seen that the waste from the industrialization of Rhei Radix et Rhizoma has high utilization value. Hence，based on the relevant literature and investigation on the application of producing areas in China and abroad，the paper summarized the utilization status of their medicinal and non-medicinal parts，the waste production in the industrialization，as well as the active substances and utilization ways and put forward the multi-level and multi-path utilization strategy of Rhei Radix et Rhizoma wastes，in order to provide reference for the rational development and application of Rhei Radix et Rhizoma resources and promote the effective utilization and green development of the corresponding wastes.
