    • PURPOSE: A compound isolated from Artemisia sylvatica, a method for isolating the same and the use thereof are provided. The compound inhibits the activity of farnesyl transferase required for activation of carcinogenic gene Ras or growth of cancer cells. CONSTITUTION: An artemisolide compound represented by the formula(1) is isolated from Artemisia sylvatica. A method for isolating artemisolide compound of the formula(1) from Artemisia sylvatica comprises the steps of: (1) extracting leaves and stems of Artemisia sylvatica with alcohol to separate an organic solvent layer; (2) subjecting the organic solvent layer to column chromatography using silica or C18 to separate an active fraction; (3) adsorbing the active fraction to the column chromatography using C18, silica gel or LH-20 and eluting it to obtain a partially purified active material; and (4) subjecting the partially purified active material to thin layer chromatography to separate an active fraction and subjecting the active fraction to HPLC.
    • 目的:提供从艾蒿分离的化合物,其分离方法及其用途。 该化合物抑制活化致癌基因Ras或癌细胞生长所需的法呢基转移酶的活性。 构成:由式(1)表示的青蒿酸酯化合物从艾蒿中分离出来。 从蒿蒿中分离出式(1)的青蒿酸酯化合物的方法包括以下步骤:(1)用醇萃取蒿蒿的叶和茎以分离有机溶剂层; (2)使用二氧化硅或C18对有机溶剂层进行柱色谱分离活性部分; (3)使用C18,硅胶或LH-20将活性级分吸附到柱色谱中,并洗脱得到部分纯化的活性物质; 和(4)将部分纯化的活性物质进行薄层色谱以分离活性级分并将活性级分进行HPLC。

    • PURPOSE: A method of preparing curcumin and a derivative thereof by extracting Curcuma longa L. is provided. The curcumin and a derivative thereof inhibit the activity of farnesyl transferase and have angiogenesis inhibiting activity and thus can be effectively use as anticancer agents, oncogene expression inhibitors, cancer metastasis suppressing agents, prophylactic agents for blindness by unwanted angiogenesis caused during diabetic retinopathy and corneal transplantation. CONSTITUTION: A pharmaceutical composition contains curcumin and a derivative thereof of the formula 1. In formula, R1 and R2 are independent each other and selected from the group consisting of OCH3 and H. Curcuma longa L. is extracted with alcohol, an organic solvent layer containing farnesyl transferase inhibiting material is separated. Thereafter, the active material dissolved in the organic solvent is subjected to chromatography to separate an active fraction, the separated active mixture is absorbed into a column and then dissolved to obtain partially purified active material. A fraction having good activity is separated using thin-layer chromatography and then purified with a column to obtain the curcumin and derivative thereof.
    • 目的:提取姜黄提取姜黄及其衍生物的方法。 姜黄素及其衍生物抑制法呢基转移酶的活性并具有血管生成抑制活性,因此可以有效地用作抗癌剂,癌基因表达抑制剂,癌转移抑制剂,糖尿病性视网膜病变和角膜移植引起的意外血管生成失明的预防剂 。 组成:药物组合物含有姜黄素及其衍生物。式中,R 1和R 2彼此独立,选自OCH 3和H.姜黄提取醇,有机溶剂层 含有法呢基转移酶抑制物质被分离。 然后,将溶解在有机溶剂中的活性物质进行色谱法分离出活性部分,将分离的活性物质吸收到柱中,然后溶解,得到部分纯化的活性物质。 使用薄层色谱分离具有良好活性的级分,然后用柱纯化,得到姜黄素及其衍生物。
