Jiyuan Dong Ling Cao, also known as Jiyuan Icing Grass, is produced in Jiyuan City, Henan Province. Containing erythromycin A, B, C and D, it also contains volatile oil alkaloids, bitter components, lactones and flavonoids, etc. Among them, erythorone and B are effective anti-tumor components for various Cancer has a certain effect. Jiyuan Donglingcao has the reputation of “Wangwu Xiancao†and because of its strong killing effect on upper respiratory tract strains such as Staphylococcus aureus and Streptococcus A, it is also known as “penicillin in traditional Chinese medicineâ€. In April 2006, the General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) approved the protection of geography-marked products of Dongling grass in Jiyuan.
Jiyuan Dongling grass is mainly distributed in the mountainous area of ​​800 to 1200 meters in the northern part of Jiyuan City. It has a mild climate, abundant rainfall, and good lighting conditions. It is extremely conducive to the growth of ice-cream grass and has a reserve of more than 1,200 tons.
Medicinal value
Jiyuan Donglingcao was first discovered in Jiyuan City of Henan Medical Science Research Institute. Prior to this, there was no record in the “Compendium of Materia Medicaâ€. Afterwards, the Institute of Botany, Chinese Academy of Sciences, Henan Medical University, Henan Institute of Medical Sciences, Henan Biosciences Co., Ltd. The research conducted by the Institute fully affirmed its anti-tumor, phytostatic, anti-cancer treatment and taste improvement functions, and was incorporated into the Pharmacopoeia of the People's Republic of China in 1977. Since Jiyuan Icegrass is a genus of genus Cinnamomum, a new variety of crushed Mia, the effective anti-cancer composition contained in saponins, namely lysine and B, is significantly higher than other producing areas. The “Land of Chinese Specialties†also lists it as Jiyuan. specialty. [3]
The main inclusions of Jiyuan rubescens are quercetin A, B, C, and D, as well as alkaloids, bitter components, lactones, and flavonoids. Among them, erythorone A and B are effective anti-tumor components and have obvious bactericidal effects. They have certain curative effects on various cancer diseases, especially on early esophageal cancer. In addition, it also has a strong killing effect on upper respiratory tract strains such as Staphylococcus aureus and Streptococcus A, and has been widely used in the clinical treatment of pharyngitis, tonsillitis and stomatitis, and is known as "penicillin in traditional Chinese medicine".
Variety characteristics
Studies have shown that: Jiyuan Dongling grass population is unique, authentic quality, its A content is 50% higher than other similar products in other places.
Jiyuan rubescens is rich in various active ingredients. Many years of research by the Institute of Botany, Kunming Institute of Botany, Henan University of Traditional Chinese Medicine and other scientific research institutions have proved that the HPLC fingerprint of Rabdosia rubra produced in Jiyuan City is completely different from that of other locally produced Rabdosia rubra, with rich active ingredients. , high content, unique population, authentic quality.
Jiyuan Donglingcao Oridonin content ≥ 0.5%, rosemary acid ≥ 0.8%, water soluble extract ≥ 30.0%. In particular, the content of oridonin is the highest, which is 50% higher than that of oridonin produced elsewhere.
protected range
The scope of protection of geography signage products of Jiyuan Donglingcao is based on the scope of the letter “Determining the scope of protection of geographical indication products of Dongling grass in Jiyuan†issued by the People's Government of Jiyuan City, Henan Province, which is the base of Jiyuan, Henan Province. Kejing Town, Chengliu Town, Wulongkou Town, Shaoyuan Town, Xieye Township, Sili Township, Wangwu Township and other seven townships now have administrative jurisdiction.
