Cyperus scariosus Extract INCI Name Cyperus Rotundus Extract CAS 85085-54-7 EINECS ELINCS No 285-381-3 Cyperus root extract Cyperus scariosus ethanol extract Cyperus scariosus aqueous-methanolic extract photo picture image In 1982, Ai-Fang Wang, and others process compare studies as for subject of isolated rat uterus to the tension and pain threshold in mice indicator,for the observation of the different Cyperus rotundus and their processed products.

 1.Isolated rat uterus spasmolysis role: Wistar female rats in vitro dissolution uterine placed in McNamara worse, with Tai's solution maintenance, and the result of ankylosing uterine cramps caused by Posterior Pituitrin,and add various processed products and hygiene decoction 3.7 * 10 (-2) g / ml, observe and compare Cyperus rotundus products in rats in vitro inhibition of uterine tension. The results show that Shanghai Method(by 1973 edition of "Shanghai concocted norms") and improved Shanghai Method(by 1973 edition of "Shanghai concocted norms", supplies to rice vinegar, not liquor.) prepared cyperus root superior tha raw crudeCyperus rotundus ( P less than 0.05), while Pharmacopoeia (1977 edition) for the two no obvious difference.

 2.Analgesic effect: female mice intraperitoneal injection of Cyperus root extraction and liquid dose of 30 g / kg, with hot plate test to determine mice pain threshold, compare analgesic effect between various cyperus root preparations. The results show that Cyperus rotundus raw root and preprared Cyperus rotundus root both raised the pain threshold in mice have increased the role, with the best come from the improved Shanghai Method, Shanghai Method, improved Pharmacopoeia Method(according to the "Chinese Pharmacopoeia" 1977 edition, but after every 100 kg slices Cyperus rotundus to vinegar 30 kg,mixed equilibrium,and drying after 2 hours.) ,followed Pharmacopoeia method prepared and raw root poor hygiene.

 In 1983, Ai-Fang Wang and others make further improve the preparation method of Cyperus rotundus concocted by the use of vinegar, and steaming, slow fire boiling time the three factors and the three level, set tension in isolated rat uterus, mice pain threshold changes observed as indicator,with orthogonal Design and test various factors and the level of effectiveness and the impact of Cyperus rotundus. The experimental results show that using vinegar and its quantity impact Cyperus rotundus quality of the main factors,strong order comes accordingly with the vinegar ratio 20%> 15%> 10%. Steaming time second, slow fire boiling time the third. Vinegar 10 kg / 50 kg ratio brings the best Cyperus rotundus prepared root, the steaming time 8 hours for the best,slow fire boiling no big impact on quality.
