    • Process to obtain and use extracts, fractions and isolated compounds from the Copaifer species for the treatment of urinary lithiasis in human beings and animals, which comprises the following steps: a) drying of aerial parts, leaves and branches from Copaifer species in a circulating hot air stove at 40 °C; b) milling of the dry material in a knife mill until a fine powder is obtained; c) extraction by cold or hot maceration in water or hydro-alcohol solution 7:3 in ethanol; d) filtration of extracts through filtration canvas to separate the plant cake; e) lyophilization of the water extract; f) concentration of hydro-alcohol extract in concentrators under reduced pressure; g) fractioning of crude extracts, obtained from the aerial parts of Copaifera species or from crude copaiba oil, by filtration processes in packing columns with stationary phases based on silica gel; or; h) obtainment of fractions rich in the active principles by liquid-liquid partition processes from the hydro-alcohol extract from the branches of the Copaifera species, using hexane, chloroform and n-butanol in sequence; i) fractioning of the fraction in hexane by using a liquid column containing silica gel and elution with hexane and hexane-ethyl acetate mixtures in increasing polarity order to isolate sesquiterpenes; i) fractioning of the fraction in chloroform by using a liquid column containing silica gel and elution with hexane, dichloromethane and methanol in increasing polarity order to isolate diterpenes of the types chlerodane, labdane and low polarity derivatives from cinnamic acid; k) fractioning of the butanol extract by using a liquid column containing silica gel and modified with the addition of acetic acid and elution with mixtures of dichloromethane and methanol to isolate acid diterpenes and polar derivatives from cinnamic acid.
    • 获得并使用来自Copaifer物种的提取物,级分和分离的化合物用于治疗人类和动物中的尿结石的方法,其包括以下步骤:a)在循环热中从Copaifer物种干燥地上部分,叶和分枝 空气炉为40°C; b)在刀磨机中研磨干材料直到获得细粉末; c)通过冷或热浸渍在水或醇溶液中7:3在乙醇中提取; d)通过过滤帆布过滤提取物以分离植物蛋糕; e)冻干水提取物; f)减压浓缩液中的醇醇提取物的浓度; g)通过基于硅胶的固定相填充柱中的过滤方法从Copaifera物种的地上部分或粗Copaiba油获得的粗提取物的分馏; 要么; h)依次使用己烷,氯仿和正丁醇从Copaifera物种的分支中提取液 - 液分离液液分离方法获得富含活性成分的馏分; i)通过使用含有硅胶的液体柱在己烷中分馏馏分,并用己烷和己烷 - 乙酸乙酯混合物以增加的极性洗脱以分离倍半萜; i)通过使用含有硅胶的液柱并用己烷,二氯甲烷和甲醇以极性极性逐步洗脱来分馏氯仿中的级分,从而从肉桂酸中分离出己烷,二氯甲烷和甲醇。 k)使用含有硅胶的液柱分馏丁醇提取物,并加入乙酸进行改性,用二氯甲烷和甲醇的混合物洗脱,从肉桂酸中分离出酸二萜烯和极性衍生物。
