The invention discloses a fatty acid-trimethyl chitosan polymer modified by a lactobionic acid, a preparation method and an application. The fatty acid-trimethyl chitosan polymer modified by the lactobionic acid is an active targeting nano micelle carrier material. A trimethyl chitosan with a good water-solubility is used as a carrier material, the hydrophobic modification is performed by a fatty acid, and then the surface modification is performed by the lactobionic acid to obtain a polymer micelle with the lactobionic acid which mediates tumor tissue target. Harmine is used as a model drug to prepare a drug-loaded nano-micelle in a rubbing and self-assembly mode. A test confirms that the drug loading capacity and encapsulated ratio of the drug-loaded nano-micelle are high, the slow-release property is achieved, cells are effectively taken in through a lactobionic acid receptor pathway, and distribution of drugs on the tumor tissue is increased, so that the curative effect is improved, the toxic and side effect is reduced, and targeted therapy is achieved. The fatty acid-trimethyl chitosan polymer modified by the lactobionic acid, the preparation method and the application provide an ideal novel drug carrier and a preparation form for antitumor drugs with slightly solubility.

The invention discloses a method for extracting peganum harmala alkaloid under microwave assistance. The method comprises the following steps: drying a peganum harmala plant to a constant weight, using ethanol with volume concentration of 60-95% as a solvent, extracting for 8-12 minutes under microwave heating assistance at a solid-liquid ratio of 10-50 ml/g and an extracting temperature of 60-100 DEG C, filtering to obtain an extracting solution, concentrating the extracting solution until no alcohol smell exists, coating the extracting solution on a preparative high performance liquid chromatography C18 reverse phase silica gel column, using 0.1 mol/L of ammonium acetate buffer salt solution and acetonitrile with a volume ratio of 70:30 to 96:4 as an elution phase, separating and preparing at a flow speed of 1.0 mL/min and within a temperature range of 20-40 DEG C, online monitoring via ultraviolet 280 nm, collecting eluant with a specific absorption peak, and volatilizing to obtain the following three alkaloids: vasicine, banisterine and harmine. The method is simple, convenient, feasible and controllable, and the yield of the alkaloid of the method is higher than that of the existing extraction methods.

The invention relates to the technical field of application of a harmine derivative, and particularly discloses the application of a harmine derivative to preparation of drugs for treating cystic echinococcosis for the first time. In-vitro pharmacodynamic experiment data prove that the harmine derivative can reduce the survival rate of echinococcosis granulosis cyst remarkably; In-vivo pharmacodynamic experiment data prove that the efficacy of the harmine derivative and the efficacy of albendazole are similar in treating cystic echinococcosis; in-vitro-and-vivo safety evaluation experiment data prove that the toxicity of the harmine derivative is lower than that of a harmine monomer with cystic echinococcosis resisting activity. Therefore, a new approach is provided for treating cystic echinococcosis.
