我们进行有关中药中环核苷的研究,曾有报道:大枣中含有高浓度的环磷腺甙与环磷鸟甙,吴茱萸中含有高浓度的环磷鸟甙。现正在进一步进行有关常用中药的水提取液中ATP活性物质的筛选。测定ATP活性系按firefly assay法进行的。现通过大量筛选,发现了药用人参,独活,百合,天麻4种生药含有较高的ATP活性物质。然而,却不认为大枣里含有多量的环磷腺甙活性物质。根据在室温下贮藏的干燥药用人参中ATP活性物逐年减少这一事实,能够推断出市售人参收获后的贮藏年限。因而认为,测定ATP活性,将有助于评
We conducted studies on the Chinese traditional medicines of the Central Cyclic Nucleoside. It has been reported that jujube contains a high concentration of cyclophosphazone and cyclophosphorus guanidine. Wujing contains a high concentration of cyclophosphorylguanidine. Screening of ATP-active substances in aqueous extracts of commonly used traditional Chinese medicines is now underway. The ATP activity was measured by the firefly assay. Through a large number of screenings, it has been found that four kinds of crude drugs including medicinal ginseng, unicorn, lily and gastrodiae contain higher ATP active substances. However, it is not considered that jujube contains a large amount of cyclophosphamide active substance. Based on the fact that ATP actives are reduced year by year in dry medicinal ginseng stored at room temperature, the shelf life of the commercially available ginseng can be inferred. Therefore, it is believed that measuring ATP activity will help
