Preparation method and application of inula japonica extract and combination thereof

The invention belongs to a method for preparing inula japonica plant extract and applications of the inula japonica extract. The plant material (root, stem, leaves, inflorescence and whole grass) of the inula japonica (including Inula japonica and Inula britannica) is crushed and extracted by a solvent which comprises 95% of alcohol; and the extract solution is concentrated to have the same weight with the inula japonica crushed matters, thus obtaining inula japonica extract. The inula japonica extract has obvious inhibition effects to cucumber botrytis cinerea, alternaria solani, cladosporium fulvum, colletotrichum lagenarium, sphaerotheca fuliginea, pseudoperonospora cubensis, potato phytophthora infestans, tomato phytophthora infestans and rhizoctonia cerialis; wherein the inflorescence extract has strong antibacterial activity. The inula japonica extract extracted by alcohol can be matched with suitable solvent and pesticide adjuvant to prepare britannica lactone emulsifiable solution and britannica lactione micro-emulsion of botanical fungicide. The inula japonica extract has obvious effects for preventing cucumber downy mildew, sphaerotheca fuliginea, tomato gray mold and tomato leaf mould, is especially suitable for prevention and control on the fungi diseases to economical crops such as vegetables and the like, and is a botanical fungicide with nuisanceless.

Extraction and separation method and application of homogeneous morinda citrifolia polysaccharides

The invention discloses an extraction and separation method and application of homogeneous morinda citrifolia polysaccharides, belonging to the field of extraction, separation and application of polysaccharides. The invention aims to solve the technical problems that components are easy to damage, consumed time is long, an extraction rate is low and the pharmacological action of the morinda citrifolia polysaccharides is not clear in conventional morinda citrifolia polysaccharide extraction methods. The method comprises the following steps: preparing coarse morinda citrifolia powder; carrying out flash extraction, concentration, alcohol precipitation, concentration and drying to obtain crude morinda citrifolia polysaccharides; carrying out deproteinization treatment and decoloration; and carrying out elution by adopting a DEAE-52 fiber column, and carrying out Sephadex G-75 gel column chromatography so as to obtain five kinds of homogeneous morinda citrifolia polysaccharides. Accordingto the invention, a morinda citrifolia polysaccharide extraction method is improved and optimized, effective components in morinda citrifolia can be reserved to the maximum extent by utilizing a flashextraction method, extraction time is remarkably shortened, and extraction efficiency is greatly improved. It is verified that the homogeneous morinda citrifolia polysaccharides have an inhibiting effect on human hepatoma carcinoma cells (HepG2). The homogeneous morinda citrifolia polysaccharides extracted by the method are applied as bioactive components for inhibiting human hepatoma carcinoma cells to preparation of antitumor drugs.

Externally-applied medicament for radical treatment of all types of cancers and difficult and complicated diseases

The invention discloses an externally-applied medicament for radical treatment of all types of cancers and difficult and complicated diseases. The treatment on the difficult and complicated diseases such as cancer and the like by using the externally-applied medicament overturns the traditional treatment modes such as oral administration, operation, chemotherapy and the like, and the externally-applied medicament is externally applied to skin acupuncture points to ensure that the components of the medicament osmoses into a body to eliminate tumors and radically treat the cancer. The medicament mainly comprises the following components: Chinese eaglewood, musk, short-pedicel aconite root, broken immortality peach, clematis root, garden balsam seed, common camptotheca fruit, rubixanthin, borax, centipede, pig bile, common selfheal fruit-spike, glaucescent fissistigma root, dragon bone, olive nut, abrus cantoniensis, decumbent bugle herb and the like. Practices prove that the externally-applied medicament has no side effect in the process of treating cancer and tumor, and the cancers and tumor cannot relapse and transfer; and compared with the traditional therapeutic method, an operation is not needed, oral administration is not needed, injection is not needed, chemotherapy is also needed, and correspondingly, the mental pressure of a patient is alleviated.
