Nettle Part Of The Pharmacological Effects And Active Ingredients, And Dry Ginger Genetic Diversity Study

1, Urtica fissa E. Pritz. is a popular used folk medicine and ethnic drug, it widely used in the Han nationality and other minority. It was contained in the "益疗方物略记"[1.2], it used in the treatment of rheumatism , reduce the pain and inflammation of bruises and sprains,skin pruritus and urticaria and so on[18]. In addition, many clinical evidence indicates that Urtica urens and Urtica dioica can treat of hyperplasia of prostate effectively, but there was no accurate account of the chemical constituents and pharmacological effects.Study on the research about withdraws the thing of U. fissa E. Pritz to the big mouse adjuvant arthritis (AA) inhibitory action. Experimental results showed that the thick polysaccharide of Urtica fissa E. Pritz differently is taken bad to the big mouse adjuvant arthritis the stage to have the certain inhibitory action, But its toxicity is smaller than the masculine comparison medicine.In addition, we firstly study on the preliminary study about withdraws the thing of U. fissa E. Pritz to the big mouse Benign prostate hyperplasia (BPH) the inhibitory action. Experimental results showed that Thenettle ethyl acetate withdraws the thing, The nettle ethyl alcohol withdraws the thing, Nettle Shui Tiwu has the certain inhibitory action to the big mouse Benign prostate hyperplasia, But the same masculine comparison medicine comparison and does nothave the significance difference. Among them, The nettle ethyl alcohol withdraws the thing and Shui Tiwu prostate gland wet weight and the index relative is small, Is strong to the big mouse Benign prostate hyperplasia inhibitory action.We study on chemical constituents of Urtica fissa E. Pritz.. Herbs of Urtica fissaE. Pritz. was investigated about its chemical component. Palmitic acid, potassium nitrate, β —daucosterol were isolated. There components could be assigned by their UV, MS, ¹HNMR, ¹³NMR. Palmitic acid and β-daucosterol were firstly separated from Urtica fissa E. Pritz.2, As a common Chinese herb, dry ginger is the dried rhizome of Zingiber officinale Roscoe (Farm. Zingiberaceae) . It's used for removing cold and stomach pain, diarrhea due to cold deficiency, cough, rheumatism and several other uses. It has the ability to lower blood cholesterol and aid in preventing internal blood clots. It is often taken to help combat colds, coughs, and the flu.Zingiber officinale was cultivated in the country's southern region cultivation since the beginning of the Ming Dynasty. the soil, The light, temperature, humidity, precipitation, and many other factors, made the different among different places. We studied on genetic diversity of Zingiber officinale Rosc. as revealed by ISSRs. But the genetic diversity had no relation with region which they growed.
