Rutin research presents vibrant prospects

Dec 06, 2019

         Rutin, also known as rutin and purple quercetin, is a wide range of flavonoids. It is mainly present in the flower buds (locust rice), fruits (solar locust) of the leguminous plant SophorajaponicaL., The whole grass of the Rutaaceae RutaraveolenslensL. In the seedlings of the Polygonaceae buckwheat (Fagopyrum esculentum Moench). Flavonoids play a pivotal role in the treatment of cardiovascular and cerebrovascular diseases, and rutin is a typical representative of them.

        As a medicinal plant active ingredient with broad development prospects, domestic scholars have studied it more in recent years. Rutin is a kind of flavonoids with various biological activities. It widely exists in the plant kingdom and has abundant reserves in China. With the development of modern medicinal chemistry and modern preparation technology, the research of rutin presents a vibrant prospect, the discovery of some new pharmacological effects (such as anti-prostate cancer, colon cancer, liver cancer, etc.) and new extraction and purification processes (such as The application of critical carbon dioxide extraction technology makes the extraction and purification of rutin more green and environmentally friendly.


        In recent years, the discovery of new sources of rutin has also made major breakthroughs. Eucalyptus urmanni introduced from Australia has been successfully planted in Sichuan. China is a big country in the production and consumption of rutin. Most of the rutin exports are exported to the European market. Due to the low added value of rutin and the low technical threshold, the export price has been controlled by some traditional export companies. Research on its derivatives should be increased. It is a future direction.

       Rutin is widely present in nature, and it is contained in almost all Rutaceae and Photinaceae plants, especially Rutae in Rutae, sophora in leguminous plants, buckwheat in Polygonaceae, and red lotus in Hypericum. , Rhamnaceae plant Guangzhi Goucha, and thistle plant wild sycamore leaves are rich in content, which can be used as raw materials for extracting rutin.

       At present, the production of rutin in China is mainly extracted from locust rice. There are many reports on the use of medicinal and food plant buckwheat as the raw material of rutin. The two types of buckwheat, sweet buckwheat and tartary buckwheat, contain rutin in different degrees in each tissue. The content of rutin in each part of tartary buckwheat is higher than that in corresponding parts of sweet buckwheat. The content of tartary buckwheat in skin, flower, leaf, stem and root parts are (%): 20.30, 17.89, 6.85 , 0.62 and 1.27, the contents of sweet buckwheat are (%): 18.20, 15.60, 5.93, 0.55 and 0.94.
